Description

  The present invention relates to a regression test support program and a regression test support apparatus.

  Regression test is a test that checks whether a program change has an unexpected effect, that is, whether an unexpected change has occurred in the functions related to the program other than the program to be changed. Say. A regression test is also performed on a Web application that provides a service using a Web page as an interface. In the regression test of the Web application, it is checked whether the Web page transition order and the display content of each Web page match the data indicating the expected value after the Web application is changed.

JP 2007-11532 A JP 2001-13861 A

  As a method for generating data indicating an expected value, for example, it is conceivable that a user operates a Web page before changing the Web application, and the display information of the Web page displayed according to the operation is recorded as the expected value. . At this time, if an operation history is also recorded, an operation on the Web page can be automatically executed based on the operation history at the time of a regression test after changing the Web application. At the time of the automatic execution, information on the displayed Web page is recorded. By comparing the display information recorded at the time of automatic execution with the display information recorded as an expected value, it is possible to confirm the presence or absence of an unexpected effect. That is, there is a possibility that an unexpected influence is included in the difference detected by the comparison.

  However, if the display information recorded before the change of the Web application is used as an expected value as it is, even the planned influence is detected as a difference. Then, it is necessary to determine whether the detected difference is an unexpected effect or a planned effect.

  In order to make such a determination unnecessary, it is conceivable to edit display information as an expected value. For example, in the display information as the expected value, editing for excluding the portion related to the planned influence from the comparison target is performed.

  In view of the necessity of such editing work, when displaying display information as an expected value, display information of all browser screens displayed in association with the Web application is recorded every time a screen transition occurs. Is desirable. Specifically, if there is a parent browser screen (parent screen) displaying the main Web page and a child browser screen (child screen) displayed in response to an operation on the Web page, two It is desirable to record the display information of one browser screen. This is because there may be a case where a new operation is added to the operation history for the parent screen that is not the operation target while the child screen is being displayed, and the new operation is executed during the regression test.

  However, when recording display information of all displayed browser screens, it may be complicated to find a browser screen to be edited.

  As a specific example, the following screen transition is assumed. First, a web page showing company information in Japanese is displayed on the parent screen (step 1). A sub-screen is displayed in response to an input to the language selection menu on the Web page, and a Web page including Japanese, English, and French as options is displayed in the sub-screen (step 2). When “English”, which is one of the options, is selected on the sub-screen, the sub-screen is closed and a Web page showing company information in English is displayed on the main screen (step 3).

  In the case of the above example, in step 1, the display information of the parent screen is recorded as data a. In step 2, the display information of the child screen is recorded as data b, and the display information of the parent screen is recorded as data c. In step 3, the display information of the main screen is recorded as data d. Therefore, four pieces of data, data a to data d, are recorded. These four pieces of data are the data that is the basis of the expected value.

  Even in the simple specific example as described above, when four pieces of data are recorded, the actual screen transition is more complicated, and the number of data to be recorded becomes large. Therefore, in the editing work phase, it may be a troublesome work to find data that is expected to be affected from a list of data recorded as expected values.

  Therefore, an object of one aspect is to provide a regression test support program and a regression test support device that can easily find data to be edited from data used as expected values in a regression test.

  In one plan, the regression test support program detects an update of the display content of any one or more browser screens displayed on the display, and every time the update is detected, The data including the information indicating the display content of the browser screen and the identification information of the browser screen related to the update is recorded in the first storage unit, and the first storage unit according to the data editing instruction And causing the computer to execute a process of displaying a list of images indicating the display contents of the browser screen related to the identification information.

  According to one aspect, it is possible to easily find data to be edited from data used as an expected value in a regression test.

To do.

  The test support apparatus 10 is a computer that supports execution of a regression test related to a Web application in the Web server apparatus 20. The regression test is a test for checking whether or not an unexpected influence is caused by the change when the program is changed or modified (hereinafter referred to as “change”). Therefore, the test support apparatus 10 supports the confirmation work of whether there is an unexpected influence due to the change of the Web application.

  FIG. 2 is a diagram illustrating a hardware configuration example of the test support apparatus according to the embodiment of the present invention. 2 includes a drive device 100, an auxiliary storage device 102, a memory device 103, a CPU 104, an interface device 105, a display device 106, an input device 107, and the like, which are mutually connected by a bus B.

  A program for realizing processing in the test support apparatus 10 is provided by the recording medium 101. When the recording medium 101 on which the program is recorded is set in the drive device 100, the program is installed from the recording medium 101 to the auxiliary storage device 102 via the drive device 100. However, the program need not be installed from the recording medium 101 and may be downloaded from another computer via a network. The auxiliary storage device 102 stores the installed program and also stores necessary files and data.

  The memory device 103 reads the program from the auxiliary storage device 102 and stores it when there is an instruction to start the program. The CPU 104 realizes functions related to the test support apparatus 10 according to a program stored in the memory device 103. The interface device 105 is used as an interface for connecting to a network. The display device 106 displays a GUI (Graphical User Interface) or the like by a program. The input device 107 is a keyboard, a mouse, or the like, and is used for inputting various operation instructions.

  An example of the recording medium 101 is a portable recording medium such as a CD-ROM, a DVD disk, or a USB memory. An example of the auxiliary storage device 102 is an HDD (Hard Disk Drive) or a flash memory. Both the recording medium 101 and the auxiliary storage device 102 correspond to computer-readable recording media.

  FIG. 3 is a diagram illustrating a functional configuration example of the test support apparatus according to the embodiment of the present invention. In the figure, the test support apparatus 10 includes a browser screen display unit 11, a comparison data generation unit 12, an editing unit 13, an inspection data generation unit 14, a comparison unit 15, and the like. Each of these units is realized by processing executed by the CPU 104 by a program installed in the test support apparatus 10. The test support apparatus 10 also includes a comparison data storage unit 16, an inspection data storage unit 17, and the like. Each of these storage units can be realized by using, for example, a storage device connected to the auxiliary storage device 102 or the test support device 10 via a network.

  The browser screen display unit 11 is realized by a process that the so-called Web browser program causes the CPU 104 to execute. The browser screen display unit 11 displays one or more browser screens (web browser windows) on the display device 102 (display thereof). The browser screen display unit 11 downloads a Web page corresponding to a URL (Uniform Resource Locator) designated for each browser screen from the Web server device 20 and displays it on the browser screen. In the present embodiment, the Web page refers to a screen displayed based on, for example, various image data referred to from an HTML (HyperText Markup Language) source or an HTML source. The page information of the Web page refers to a set of various image data or the like referenced from the HTML source or the HTML source.

  The comparison data generation unit 12 generates data (hereinafter referred to as “comparison data”) to be compared with data obtained at the time of inspection after the change of the Web application as an expected value in the regression test. The generated comparison data is recorded in the comparison data storage unit 16. The comparison data is generated with respect to the Web page generated by the Web application before change.

  In the figure, the comparison data generation unit 12 includes an event detection unit 121, a proxy unit 122, a comparison data recording unit 123, and the like. The event detection unit 121 detects various events that occur on the browser screen. As an example of the event, for example, the start or end of reading a Web page, an operation on the Web page, and the like can be given. The proxy unit 122 monitors the communication content between each browser screen and the Web application. The proxy unit 122 acquires the page information of the Web page displayed on each browser screen by monitoring the communication content. The comparison data recording unit 123 records the event detected by the event detection unit 121 and the content of the Web page acquired by the proxy unit 122 in the comparison data storage unit 16.

  The editing unit 13 executes processing for editing the comparison data. That is, since the comparison data is generated with respect to the Web application before the change, the comparison data includes an inappropriate part as a comparison target with the Web page generated by the Web application after the change. When a partial change of the Web page is scheduled due to the change of the Web application, the editing unit 13 performs editing according to the partial change on the comparison data in accordance with an instruction from the user.

  The inspection data generation unit 14 acquires page information of a Web page generated by the Web application after the change, and records data including the page information (hereinafter referred to as “inspection data”) in the inspection data storage unit 17. To do. In the figure, the inspection data generation unit 14 includes an operation execution unit 141, an inspection data recording unit 142, and the like. The operation execution unit 141 executes the operation indicated by the operation history included in the comparison data recorded in the comparison data storage unit 16 on the browser screen displayed by the browser screen display unit 11. The inspection data recording unit 142 records, in the inspection data storage unit 17, events detected in response to operations performed by the operation execution unit 141 on browser images, page information of Web pages displayed on the browser screen, and the like. .

  The comparison unit 15 compares the comparison data recorded in the comparison data storage unit 16 with the inspection data recorded in the inspection data storage unit 17 and outputs a comparison result. By referring to the comparison result, the tester can check whether there is an unexpected influence due to the change of the Web application.

  Hereinafter, a processing procedure executed by the test support apparatus 10 will be described. FIG. 4 is a flowchart for explaining an example of an outline of a processing procedure executed by the test support apparatus.

  In step S101, the comparison data generation unit 12 performs a comparison data generation process. In the comparison data generation process, the comparison data generation unit 12 activates the browser screen display unit 11. The comparison data generation unit 12 stores the page information of the web page displayed on the browser screen displayed by the browser screen display unit 11 and the history of user operations on the web page in the comparison data storage unit 16 in time series, for example. Record. The page information of the Web page is generated by the Web application in response to an HTTP request transmitted from the browser screen display unit 11 to the Web server device 20 and is returned to the browser screen display unit 11.

  Subsequently, the editing unit 13 executes a comparison data editing process (S102). The editing unit 13 displays a comparison data editing screen on the display device 102, and receives an instruction to edit comparison data on the comparison data editing screen. The editing unit 13 reflects the contents of the editing instruction on the comparison data.

  Subsequently, for example, the Web application in the Web server device 20 is updated (replaced) by the tester with the changed one. That is, Steps S101 and S102 are executed for the Web application before the change, and Steps S103 and S104 described later are executed for the Web application after the change.

  In step S103, the inspection data generation unit 14 executes inspection data generation processing. In the inspection data generation process, the inspection data generation unit 14 performs each operation indicated by the operation history recorded in the comparison data storage unit 16 on the browser screen. The inspection data generation unit 14 records inspection data including page information of a web page displayed on the browser screen in accordance with execution of the operation in the inspection data storage unit 17.

  Note that the steps in FIG. 4 do not have to be executed synchronously. That is, each step may not be executed continuously as a series of processes.

  Next, details of step S101 will be described. FIG. 5 is a flowchart for explaining an example of the processing procedure of the comparison data generation processing.

  The comparison data generation unit 12 receives an input of a URL related to a Web application to be subjected to a regression test from the user in response to an instruction input for starting generation of comparison data (S201). The URL is input through, for example, a dialog that the comparison data generation unit 12 displays on the display device 102. However, the URL may be recorded in advance in a predetermined file.

  Subsequently, the comparison data generation unit 12 designates the URL and activates the browser screen display unit 11 (S202). The browser screen display unit 11 (Web browser) is activated in the process of the comparison data generation unit 12. As a result, the comparison data generation unit 12 displays each browser screen displayed by the browser screen display unit 11 via an API (Application Program Interface) (hereinafter referred to as “browser API”) provided by the browser screen display unit 11. Can be manipulated as an object. The event detection unit 121 of the comparison data generation unit 12 registers an event handler via the browser API. An event handler is a function for receiving notification of an event that has occurred on the browser screen.

  Subsequently, the comparison data recording unit 123 of the comparison data generating unit 12 displays the operation content related to activation of the browser screen display unit 11 (such as a web browser activation command and a URL specified in the activation command) as an operation history for the browser screen. Is recorded in the comparison data storage unit 16 (S203).

  On the other hand, the browser screen display unit 11 displays one browser screen (hereinafter referred to as “parent screen”) on the display device 102 in response to the activation, and reads (downloads) the page information related to the designated URL. Let the parent screen execute. When starting to read page information, the parent screen generates an event indicating this (hereinafter referred to as “reading start event”). The event detection unit 121 of the comparison data generation unit 12 detects the reading start event via the event handler and stores that the parent screen has started reading.

  When the reading of the page information by the parent screen is started (Yes in S204), the proxy unit 122 monitors the communication content between the parent screen and the Web server device 20 in the reading process (downloading process), and from the Web server device 20 Get page information to be replied. The comparison data recording unit 123 records the page information acquired by the proxy unit 122 in the comparison data storage unit 16 (S205).

  Step S205 will be described in more detail. FIG. 6 is a diagram for explaining an example of a method for acquiring and recording page information.

  As shown in the figure, the proxy unit 122 monitors the communication content by relaying (mediating) communication between the browser screen and the Web server device 20 (S205a, S205b). The relay of communication by the proxy unit 122 is performed by the same mechanism as that of a general proxy server. Therefore, the IP address and port number of the proxy unit 122 may be set as the IP address and port number of the proxy server for the browser screen display unit 11. The proxy unit 122 notifies the comparison data recording unit 123 of the page information acquired by monitoring the communication content (S205c). The comparison data recording unit 123 records the notified page information in the comparison data storage unit 16 (S205d).

  In FIG. 6, a rectangle indicating the browser screen indicates an object corresponding to the browser screen when viewed from the comparison data generation unit 12. The object is generated for each browser screen.

  When the main screen finishes reading the page information, the main screen displays the web page in the main screen based on the page information. Also, the parent screen generates an event indicating the end of reading (hereinafter referred to as “reading end event”) in response to the end of reading page information. The event detection unit 121 detects a read end event via an event handler. When a reading end event is detected for all browser screens in which a reading start event is detected, the event detection unit 121 determines that the page information reading process has been completed (Yes in S206). Therefore, the event detection unit 121 notifies the comparison data recording unit 123 of the identifier of the browser screen (hereinafter referred to as “representative screen”) from which the reading event was last detected, along with the completion of the reading process.

  That is, the event detection unit 121 waits for notification of completion of the reading process to the comparison data recording unit 123 until a reading end event is detected for all browser screens in which a reading start event is detected according to the same operation. . Such behavior by the event detection unit 121 considers a case where page information is read in parallel on a plurality of browser screens. For example, when a link on a Web page displayed on the parent screen is clicked, a new browser screen (child screen) is displayed, and page information is read on the child screen, and a new page is also displayed on the parent screen. This is a case where information is read.

  In the description so far, only one browser screen (parent screen) is displayed, so the parent screen is the representative screen. Therefore, the event detection unit 121 notifies the comparison data recording unit 123 of the identifier of the parent screen together with the completion of reading in response to the detection of the reading end event from the parent screen.

  In response to the notification, the comparison data recording unit 123 acquires a screen shot (image data) of the representative screen (here, the main screen) related to the notified identifier, and compares the screen shot in association with the identifier of the parent screen. The data is recorded in the data storage unit 16 (S207).

  Step S207 will be described in more detail. FIG. 7 is a diagram for explaining an example of a method for acquiring a screen shot of the browser screen.

  The comparison data recording unit 123 acquires a screen shot via the browser API from the browser screen corresponding to the identifier notified from the event detection unit 121 (S207a). The comparison data recording unit 123 records the acquired screen shot in the comparison data storage unit 16 in association with the identifier of the browser screen (S207b).

  Subsequently, the comparison data recording unit 123 records the division of the comparison data in the comparison data storage unit 16 (S208). The comparison data delimiter is information indicating a delimiter of a period during which the page information of the browser screen being displayed remains unchanged. In other words, the comparison data break is recorded when the page information of any browser screen being displayed changes.

  In the present embodiment, the unit of the comparison data is defined by the delimiter. That is, the recorded content between the breaks is counted as one comparison data. For the sake of convenience, the interval between the start of recording the comparison data and the first interval is also referred to as an interval.

  FIG. 8 is a diagram illustrating a configuration example of comparison data. In the figure, the first segment p1 is distinguished as comparison data 1, and the second segment p2 is distinguished as comparison data 2. Comparison data 1 is comparison data recorded for the parent screen. That is, it is comparison data in which information until the page information of the parent screen is read is recorded. The comparison data 2 is comparison data recorded by the process described in step S209 and subsequent steps.

  One comparison data (comparison data between breaks) includes an operation history, page information, a representative screen screenshot, and the like. The operation history is a history of operations performed on the Web page until the break is recorded. The operation history in the comparison data 1 includes a Web browser activation command, a URL specified in the activation command, and the like recorded in step S203.

  The page information is synonymous with the page information described above, and includes a set of data for displaying a Web page such as an HTML source and attached data. The attached data is data referred to from an HTML source such as image data. The page information of the comparison data 1 includes page information for the parent screen.

  The representative screen screenshot is a screen shot of the representative screen and an identifier of the representative screen. Basically, the screen shot of the representative screen is acquired and recorded immediately before the break is recorded. Therefore, one representative screen screenshot is included in one comparison data. The representative screen screenshot of the comparison data 1 is a screen shot of the parent screen.

  Note that the division of comparison data is not limited to predetermined information. For example, when one comparison data is recorded in one file, the comparison data delimiter corresponds to a file delimiter. When one comparison data is recorded in one record of the database, the comparison data delimiter corresponds to the record delimiter.

  Subsequently, when the event detection unit 121 detects any event for the Web page on any of the displayed browser screens (Yes in S209), the comparison data recording unit 123 displays the new comparison data after the separation. As the operation history, information (operation information) indicating the operation content is recorded (S210). For example, after the separation is recorded for the comparison data 1, the new comparison data after the separation (hereinafter referred to as “current comparison data”) is the comparison data 2.

  Step S210 will be described in more detail. FIG. 9 is a diagram for explaining an example of an operation recording method.

  When a user performs an operation on a web page displayed on the browser screen (S209a), the browser screen events an event related to the operation via an event handler set via the web browser API. The detection unit 121 is notified (S209b). The event detection unit 121 notifies the comparison data recording unit 123 of the operation information included in the event (S209c). The comparison data recording unit 123 records the operation information in the operation history of the current comparison data in the comparison data storage unit 16 (S210).

  When the operation does not start reading new page information (No in S211), the event detection unit 121 waits for detection of an event (S209). If the operation is to start reading new page information (Yes in S211), steps S205 to S208 are executed for the page information. The reading of new page information is not only the reading of new page information on the browser screen displaying the Web page that is the operation target, but also the display of a new browser screen (child screen) and the child screen. Also referred to as loading new page information.

  For example, the comparison data 2 in FIG. 8 shows a case where a small screen is displayed. Therefore, the comparison data 2 includes page information of the parent screen and page information of the child screen. Note that the sub-screen page information in the comparison data 2 is acquired by the proxy unit 122 as described in FIG. On the other hand, when the page information is not read on the parent screen, the page information of the parent screen in the comparison data 2 is copied from the comparison data 1. However, instead of copying, reference information indicating that the page information of the parent screen is the same as the page information in the comparison data 1 may be recorded. By doing so, the amount of comparison data can be reduced.

  Thereafter, steps S209 to S208 are repeated until all browser screens are closed.

  Here, the recorded content of the comparison data will be described based on a specific example of transition of the Web page. FIG. 10 is a diagram illustrating a transition example of the browser screen for explaining the recorded content of the comparison data.

  In the figure, (1) shows a state in which the parent screen W1 is displayed and the page information of the top page is read into the parent screen W1. In this case, the page information is recorded in the comparison data 1. Further, in accordance with the end of reading of the page information on the parent screen W1, a screen shot of the parent screen W1 is recorded in the comparison data 1, and a break of the comparison data 1 is recorded. In addition, the horizontal line in the same figure shows the said division | segmentation.

  (2) shows a state in which the button B1 of the Web page displayed on the parent screen W1 is clicked and the child screen W2 is displayed according to the operation. In this case, the click of the button B1 is recorded in the operation history of the comparison data 2. Further, page information of the parent screen W1 and the child screen W2 is recorded in the comparison data 2. The page information of the parent screen W1 is copied from the comparison data 1. Further, in accordance with the end of reading the page information of the sub-screen W2, a screen shot of the sub-screen W2 is recorded in the comparison data 2, and a break of the comparison data 2 is recorded.

  (3) shows a state in which “Japan” is selected in the sub-screen list L1. In this case, the selection operation is recorded in the operation history of the comparison data 3. Note that page information is not read (updated) in any browser screen in accordance with the selection operation, and therefore, page information, representative screen screen shots, and separation are not recorded at this point.

  (4) shows a state in which the child screen W2 is closed and Japanese page information is read into the parent screen W1 in accordance with the selection of “Japan”. In this case, the page information of the parent screen W1 and the page information of the child screen W2 before the update (state (3)) and the new page information of the parent screen W1 are recorded in the comparison data 3. The page information of the parent screen W1 and the page information of the child screen W2 before the update are copied from the comparison data 2. Further, in accordance with the end of reading new page information, a screen shot of the parent screen W1 is recorded in the comparison data 3, and a break of the comparison data 3 is recorded.

  Next, details of step S102 will be described. FIG. 11 is a flowchart for explaining an example of the processing procedure of the comparison data editing process.

  For example, when the comparison data editing instruction is input by the user, the editing unit 13 reads the representative screen screenshot and the representative screen identifier from each comparison data recorded in the comparison data storage unit 16 (S301). .

  Subsequently, the editing unit 13 causes the display device 102 to display a comparison data editing screen including a list of thumbnails of the representative screen screenshot (S302).

  FIG. 12 is a diagram illustrating an example of the comparison data editing screen. In the figure, the comparison data editing screen 500 includes an editing object selection area 510, a selection screen display area 520, an operation history display area 530, and the like.

  In the edit target selection area 510, a list of thumbnails of the representative screen screenshot read in step S301 is displayed in the recording order (that is, time series) of comparison data including the representative screen screenshot.

  In the selection screen display area 520, a Web page is displayed based on the page information of the representative screen related to the thumbnail selected in the editing target selection area 510. That is, the selection screen display area 520 can display the Web page by interpreting the page information, like the browser screen.

  In the operation history display area 530, an operation history of comparison data including the representative screen screenshot displayed in the selection screen display area 520 is displayed.

  Here, one of the points to be noted is that the list of thumbnails displayed in the edit target selection area 510 is limited to the representative screen. The representative screen is considered to be a browser screen that is likely to be noticed by the user among one or more browser screens displayed at the same time. For example, among the browser screens in the states of (1) to (4) in FIG. 10, the browser screen that the user pays attention to is changed as shown in FIG. 13.

  FIG. 13 is a diagram for explaining a transition example of a user's attention destination. The screen transition in FIG. 13 is the same as in FIG.

  In FIG. 13, the user first pays attention to the parent screen W1 in (1). Subsequently, in (2), when the child screen W2 is displayed, attention is paid to the child screen W2. When the child screen W2 is closed and the parent screen W1 is updated, the user pays attention to the updated parent screen W1 in (4).

  As described in FIG. 10, the parent screen W1 of (1), the child screen W2 of (2), and the parent screen W4 of (3) are representatives of the comparison data 1, the comparison data 2, or the comparison data 3, respectively. It is a screen. Therefore, the display target in the edit target selection area 510 is not limited to all the browser screens (1) to (4), but is limited to the representative screen. A list of editing candidates can be shown in a manner consistent with the transition. As a result, the user can easily find out the browser screen to be edited.

  Subsequently, when any thumbnail is selected in the edit target selection area 510, the editing unit 13 displays the content of comparison data (hereinafter referred to as “target comparison data”) including a representative screen screenshot related to the thumbnail. Is displayed on the comparison data editing screen 500 (S304). For example, a Web page based on the page information of the representative comparison target data is displayed in the selection screen display area 520. Further, the operation history included in the target comparison data is displayed in the operation history display area 530.

  Subsequently, the editing unit 13 edits the target comparison data in accordance with an editing instruction input by the user (S305). For example, when the tab t1 of the comparison data editing screen 500 is selected, the editing unit 13 displays a list screen of data (HTML source, attached data, etc.) constituting the page information of the target comparison data. Here, each comparison data includes page information of all Web pages displayed between the corresponding divisions of the comparison data. Therefore, the user can input an editing instruction regarding the page information of all the Web pages via the list screen displayed by selecting the tab 1.

  For example, the user selects arbitrary page information and inputs an instruction to exclude the page information from the comparison target with the inspection data. In response to the instruction, the editing unit 13 records information indicating that the page information is excluded from the comparison target in the comparison data storage unit 16. By doing so, it is possible to avoid that page information relating to a Web page that is no longer displayed due to a change in the Web application is compared with the inspection data.

  Further, the user displays the contents of the HTML source included in the arbitrary page information, and inputs an instruction to exclude a part thereof from the comparison target with the inspection data, for example, by specifying a range. In response to the instruction, the editing unit 13 records information indicating that the part is excluded from the comparison target in the comparison data storage unit 16. By doing so, when a part of a certain Web page is changed due to a change in the Web application, it can be avoided that the part is compared with the comparison data.

  Further, the operation history is edited in the operation history display area 530 as necessary. For example, when an arbitrary display component on the Web page displayed in the selection screen display area 520 is selected, the editing unit 13 highlights a line corresponding to the operation related to the display component in the operation history display area 530. Let The user changes, for example, an input value for the display component in the highlighted line. Alternatively, an operation for a display component that is no longer displayed due to a change in the Web application may be deleted from the operation history.

  In addition, another browser screen that is displayed (simultaneously) with the representative screen selected in the edit target selection area 510 can be displayed in the selection screen display area 520, and operations related to the browser screen can be edited. . Specifically, in the list box 521, the identification information of the Web page related to the page information that is currently displayed in the selection screen display area 520 is displayed. When the button of the list box 521 is clicked, the editing unit 13 displays a list of Web page identification information related to each page information included in the comparison data currently being displayed as options. When the user selects any option from the list, the editing unit 13 causes the selection screen display area 520 to display a Web page based on the page information corresponding to the selected option. The user can edit the operation related to the Web page as described above by operating the displayed Web page.

  The editing of operations related to browser screens other than the representative screen will be described in more detail using specific examples. Here, the following browser screen transition is taken as an example.

  FIG. 14 is a diagram for explaining a transition example of the browser screen for explaining the editing of the operation history. Note that the transition of the browser screen in the figure is irrelevant to the transition of the browser screen in FIG. Therefore, the comparison data 1, 2, and 3 relating to FIG. 14 are irrelevant to the comparison data 1, 2, and 3 in FIG.

  In the figure, (1) shows a state in which the main screen W3 is displayed. (2) shows a state in which a sub-screen W4 indicating an address corresponding to the postal code is displayed when the postal code is input to the main screen W3 and the button B2 is clicked. (3) shows a state in which the Web page on which the address on the child screen W4 is transcribed is displayed on the parent screen W3 in response to clicking on the OK button on the child screen W4.

  In the figure, the horizontal line indicates the division of comparison data. Therefore, comparison data 1 is recorded for the state (1), comparison data 2 is recorded for the state (2), and comparison data 3 is recorded for the state (3). The representative screen in the comparison data 1 is the parent screen W3 in the state (1), the representative screen in the comparison data 2 is the child screen W4 in the state (2), and the representative screen in the comparison data 3 is This is the child screen W3 in the state (3). Therefore, thumbnails of these three representative screens are displayed in the editing target selection area 510 of the comparison data editing screen 500.

  When the thumbnail of the representative screen of the comparison data 2 is selected from the thumbnails of these three representative screens, the editing unit 13 selects a Web page based on the page information corresponding to the representative screen in the comparison data 2 as a selection screen display area. 520 is displayed. Further, the editing unit 13 causes the operation history display area 530 to display the operation history included in the comparison data 2.

  In this state, when the user selects the button of the list box 521, the editing unit 13 displays the Web page identification information related to the page information of the child screen W4 in (2) and the page information of the parent screen W3 in (2). A list including the identification information of the Web page according to the selection is displayed. When the user selects an option corresponding to the parent screen W3, the editing unit 13 causes the selection screen display area 520 to display a Web page based on the page information of the parent screen W3. At this time, the display content of the selection screen display area 520 is the same as the parent screen W3 of (1) in FIG. In addition, since the input value etc. are not contained in page information, the display content based on page information becomes the same as the main screen W3 of (1) instead of (2) of FIG.

  In this state, when the user clicks a text box for inputting a zip code, the editing unit 13 highlights a line corresponding to a value input operation for the text box in the operation history display area 530. The user changes the input value for the text box from “105” to “211” in the row. As a result, operations related to the browser screen other than the representative screen are changed.

  As described above, since operations related to browser screens other than the representative screen may be subject to editing, in the present embodiment, not only the page information of the representative screen but also other (that is) displayed together with the representative screen. The page information on the browser screen is also recorded in the comparison data.

  Note that, by changing the input value of the zip code for the parent screen W3 in (2) of FIG. 14, the page information of the child screen W4 does not match between the comparison data and the inspection data. This is because the address corresponding to the postal code “211” is displayed on the sub-screen W4 when the inspection data is generated. Therefore, in such a case, for example, the page information of the child screen W4 of the comparison data 2 and the page information of the parent screen W3 of the comparison data 3 may be excluded from comparison targets.

  Steps S303 to S305 are repeated each time a thumbnail is selected in the edit target selection area 510.

  Next, details of step S104 in FIG. 4 will be described. FIG. 15 is a flowchart for explaining an example of the processing procedure of the inspection data generation processing.

  For example, when an inspection data generation instruction is input by the user, the operation execution unit 141 of the inspection data generation unit 14 reads the operation history of all comparison data stored in the comparison data storage unit 16 (S401). Subsequently, the operation execution unit 141 automatically executes the first operation in the read operation history (S402). Usually, the first operation is execution of a start command of a Web browser in which a URL is specified. Subsequently, the inspection data recording unit 142 of the inspection data generating unit 14 records the inspection data in the inspection data storage unit 17 (S403). The processing content of step S403 may be the same as that of steps S209 to S208 of FIG. Therefore, the inspection data is recorded so as to have the same configuration as the comparison data.

  Thereafter, steps S402 and S403 are repeated in order of operation (in time series) for all operations included in the operation history read from the comparison data (S404).

  Next, details of step S105 in FIG. 5 will be described. FIG. 16 is a flowchart for explaining an example of the processing procedure of the comparison process.

  For example, when a comparison instruction between the comparison data and the inspection data is input by the user, the comparison unit 15 reads one comparison data from the comparison data storage unit 16 (S501). Subsequently, the comparison unit 15 reads one inspection data from the inspection data storage unit 17 (S502). Note that the reading order of the comparison data and the inspection data is the order in which they are recorded (in chronological order).

  Subsequently, the comparison unit 15 acquires one page information from the read comparison data in the recording order (S503). Subsequently, the comparison unit 15 acquires one page information from the read inspection data in the recording order (S504). Subsequently, the comparison unit 15 compares the acquired two pieces of page information (S505). The comparison unit 15 records the comparison result in the memory device 103 or the auxiliary storage device 102, for example.

  Steps S503 to S505 are executed for all page information of the read comparison data (S506). However, the page information to be compared may be limited to the page information read in the comparison data. That is, the page information copied from the comparison data before the comparison data may not be the comparison target. This is because such page information is compared at the time of comparison with the inspection data regarding the previous comparison data. Note that the page information copied from the comparison data before the comparison data is, for example, the page information of the parent screen W1 in the comparison data 2 according to the example of FIG.

  When steps S501 to S506 are executed for all the comparison data recorded in the comparison data storage unit 16 (Yes in S507), the comparison unit 15 causes the display device 102 to display the recorded comparison results ( S508).

  As described above, according to the present embodiment, each time the update of the page information is completed according to one operation, the screen shot of the browser screen related to the update is acquired, To be recorded. Therefore, when the comparison data editing screen 500 is displayed, the editing candidate display area 510 can display the editing candidate browser screen (comparison data) only on the browser screen that the user has focused on. Therefore, it is possible to easily find the page information to be edited from all the page information included in the comparison data.

  When recording the comparison data, if the identifier of the representative screen is recorded, the screen shot of the representative screen may not necessarily be recorded. For example, when the comparison data editing screen 500 is displayed, a thumbnail of the representative screen may be generated based on the page information of the representative screen. However, in consideration of the performance when the comparison data editing screen 500 is displayed, it is preferable that a screen shot of the representative screen is recorded when the comparison data is recorded.

  In the comparison data editing screen 500, a browser screen other than the representative screen can be displayed, and operations related to the browser screen can be edited. Therefore, even if the display target as a thumbnail is limited to the representative screen, the editable range is not limited.

  In the present embodiment, the page information is an example of information indicating the display content of the browser screen. The identifier of the representative screen is an example of screen identification information related to the update. The comparison data storage unit 16 is an example of a first storage unit. The inspection data storage unit 17 is an example of a second storage unit. The event detection unit 121 is an example of a detection unit. The comparison data recording unit 123 is an example of a first recording unit. The editing unit 13 is an example of a display unit.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to such specific embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation・ Change is possible.
