<A. Embodiment 1>
<A-1. Configuration>
The monitoring screen test support device according to the present embodiment reduces the burden of visually confirming the test results by appropriately collecting and displaying the screen test results of the screen (monitoring screen) for monitoring the control target such as the plant. To do.

  FIG. 1 is a block diagram illustrating a configuration of the monitoring screen test support apparatus according to the present embodiment. The monitoring screen test support device includes a monitoring screen information storage unit 1, a monitoring screen generation unit 2, a screen image storage unit 3, a screen image storage information storage unit 4, a test item information storage unit 5, a test result pattern information storage unit 6, a test Item automatic execution means 7, test result creation means 8, and display means 9 are provided. The test result creation means 8 includes a test result comparison means 8a, a test result aggregation means 8b, a test result pattern information addition means 8c, and a test result information storage means 8d.

  The monitoring screen information storage unit 1 stores a plurality of monitoring screen information for each monitoring screen. The monitoring screen information includes the display position coordinates of drawing parts such as buttons and icon images, information on the monitoring target assigned to the drawing parts, and the like, and each is identified by a unique monitoring screen ID.

  The monitoring screen generation unit 2 generates a monitoring screen based on the monitoring screen information read from the monitoring screen information storage unit 1. In addition, the monitoring screen is changed in response to input from the test item automatic execution means 7. Here, the input from the test item automatic execution means 7 includes, for example, transmission of test data related to the monitoring target assigned to the drawing component, operation of pressing a button on the drawing component such as a button on the monitoring screen, and text input. To do. The monitoring screen generation means 2 that has received these pieces of information changes, for example, the color or shape of the drawing component, the icon image, or the display character string.

  The test item information storage unit 5 stores test item information. As illustrated in FIG. 2, the test item information includes a monitoring screen ID to be tested, major classification information, middle classification information, minor classification information, and test procedure information, and each is identified by a unique test item ID. . In FIG. 2, one line in the table represents one piece of test item information. The test procedure information is information indicating specific test contents. For example, “test data 3.0 transmission” or drawing of buttons, text boxes, etc. on the monitoring screen for the monitoring target assigned to the drawing part. For example, “button A pressed”, “input“ hoge ”in text box B”, or a combination of these. The small classification information is information obtained by abstracting the test procedure information based on the purpose of the test, and corresponds to, for example, “upper limit test”, “administrator user test”, and the like. Medium classification information is a higher level concept of small classification information. For example, small classification information “normal value test”, “upper limit value test”, “upper limit value abnormal test”, “lower limit value test”, “lower limit value” The “abnormality test” is summarized in the middle classification information “upper and lower limit test”. Further, the small classification information “administrator user test” and “general user test” are collected into the medium classification information “user authentication test”. The large classification information is information that summarizes the medium classification information with respect to the test target, that is, information indicating the test target. For example, “test of the monitoring target pump A” or “test of the screen component user authentication component group” or the like is applicable. .

  The test item automatic execution means 7 takes out the test item information from the test item information storage means 5 and executes the contents of the test procedure information.

  The screen image storage unit 3 stores information on the monitoring screen generated by the monitoring screen generation unit 2. The monitoring screens before and after the test items are associated with the test item IDs and stored as screen image storage information.

  The screen image storage information storage unit 4 stores the screen image storage information stored by the screen image storage unit 3. The screen image storage information storage unit 4 stores a plurality of screen image storage information, and each screen image storage information is uniquely identified by the test item ID associated with the screen image storage unit 3.

  The test result comparison unit 8a determines, based on the screen image storage information stored in the screen image storage information storage unit 4, the test result of the test item in which both the screen images before the test item implementation and the screen images after the test item implementation are equal. Are determined to be the same test result.

  The test result aggregating unit 8b creates test result information in which a plurality of pieces of test item information determined to be the same test result by the test result comparing unit 8a are aggregated. 3A shows test result information before aggregation by the test result aggregating means 8b, and FIG. 3B shows test result information aggregated by the test result aggregating means 8b. As shown in FIG. 3A, in the test items ID1 to ID3, the screen images before the test items are implemented are the same as the screen images after the test items are implemented. Therefore, the test result aggregating unit 8b creates test result information in which these test items are integrated into one (FIG. 3B). The test result aggregating unit 8b aggregates the test result information for each medium classification information and stores it in the test result information storage unit 8d.

  The test result pattern information storage means 6 stores a plurality of test result pattern information indicating combinations of test items with the same test result. The test result pattern information includes a combination of a test result pattern name and a plurality of pieces of small classification information with the same test result. Hereinafter, the middle classification information “upper / lower limit test” in FIG. 2 will be described as an example. The middle classification information “upper / lower limit test” includes five sub-classification information “normal value test”, “upper limit value test”, “upper limit value abnormal test”, “lower limit value test”, and “lower limit value abnormal test”. . At this time, as a test result pattern, for example, as shown in FIG. 4A, the normal value test, the upper limit value test, and the lower limit value test are the same test result, and the upper limit value abnormality test and the lower limit value abnormality test are the same test result. The test result pattern name “normal value / abnormal value 2-color-coded pattern” can be considered. Further, as shown in FIG. 4B, the test result pattern name “normal value” in which the normal value test, the upper limit value test, and the lower limit value test are the same test results, and the upper limit value abnormality test and the lower limit value abnormality test are different. “Upper limit abnormal value / Lower limit abnormal value 3-color pattern” is considered. Such test result pattern information is stored in the test result pattern information storage means 6. Here, only the combination of small classification information that gives the same test result is considered, and the content of the screen image itself is not considered.

  The test result pattern information adding unit 8c searches the test result pattern information storage unit 6 for test result pattern information that matches each of the middle classification information with respect to the test result information stored in the test result information storage unit 8d. The test result pattern name of the matching test result pattern information is added to the test result. If it does not match any of the test result pattern information, no information is added or a message indicating that the information does not match is added. The test result information subjected to the above processing is stored again in the test result information storage unit 8d. At this stage, the test result information includes a test item ID, major classification information, middle classification information, minor classification information, a test procedure, test result pattern information, and screen image storage information. This test result information is output to the display means 9 in the form of a table as shown in FIG. 5, for example, and displayed.

  FIG. 16 is a hardware configuration diagram for realizing the monitoring screen test support device of the present embodiment. The monitoring screen test support device is realized by a personal computer 12, a keyboard 16, a mouse 17, and a display 18. The keyboard 16 and mouse 17 are connected to the personal computer 12 as input devices, and the display 18 is connected as a display device. The personal computer 12 includes a CPU 13 as an arithmetic processing device, a memory 14 as a storage device, and a hard disk drive 15.

  Among the components of the monitoring screen test support apparatus shown in FIG. 1, the monitoring screen information storage means 1, the screen image storage information storage means 4, the test item information storage means 5 and the test result pattern information storage means 6 are a memory 14 or a hard disk. It is mounted on the drive 15. The monitoring screen generation means 2, screen image storage means 3, test item automatic execution means 7 and test result creation means 8 are stored as programs in the memory 14 or the hard disk drive 15 and executed by the CPU 13. The display means 9 corresponds to the display 18, for example.

<A-2. Operation>
The operation of the monitoring screen test support apparatus according to the present embodiment will be described with reference to the flowchart shown in FIG. First, the test item automatic execution means 7 extracts the test item information from the test item information storage means 5 and executes the test item (step S1000). Next, the test result comparison unit 8a and the test result aggregation unit 8b aggregate the test results using the screen image storage information created as a result of the execution of the test items (step S2000). Then, the test result pattern information adding means 8c adds test result pattern information that matches from the test result pattern information storage means 6 to the aggregated test results (step S3000). Thereafter, the test result creating means 8 outputs the test result to which the test result pattern information is added, for example, to the display means 9 (step S4000).

  Hereinafter, specific operations in the test item automatic execution process in step S1000, the test result aggregation process in step S2000, and the test result pattern information addition process in step S3000 in FIG. 6 will be described.

  FIG. 7 is a flowchart showing details of the test item automatic execution process (step S1000 in FIG. 6). First, the test item automatic execution means 7 reads the test item information from the test item information storage means 5, gives the monitoring screen ID to be tested to the monitoring screen generation means 2, and gives the test item ID to the screen image storage means 3 (step). S1100). The monitoring screen generation means 2 takes out the monitoring screen information corresponding to the monitoring screen ID given from the test item automatic execution means 7 from the monitoring screen information storage means 1 and generates a monitoring screen (step S1200). Next, the screen image storage unit 3 stores the monitoring screen generated in step S1200 as a screen image before the test item is implemented, and is linked to the test item ID given from the test item automatic execution unit 7 to display the screen image. The stored information is stored in the storage information storage unit 4 (step S1300).

  Next, the test item automatic execution means 7 executes the contents of the test procedure of the test item information read in step S1100 (step S1400). The monitoring screen generation unit 2 changes the monitoring screen generated in step S1200 according to the content of the executed test procedure (step S1500). However, if the status of the monitoring screen is not affected by the content of the executed test procedure, the monitoring screen is not changed. Next, the screen image storage means 3 stores the monitoring screen for which the processing of step S1500 has been completed as a screen image after the test item is implemented, and is associated with the test item ID given from the test item automatic execution means 7 to store the screen image. The information is stored in the information storage unit 4 (step S1600). Next, it is determined whether or not unprocessed test item information exists in the test item information storage unit 5 (step S1700), and if there is, the processing from step S1100 to step S1700 is repeated. If it does not exist, the process ends.

  FIG. 8 is a flowchart showing details of the test result aggregation process (step S2000 in FIG. 6) in the test result creating means 8. The test result creating means 8 first reads test item information from the test item information storage means 5 in units of middle classification information (step S2100). Further, the screen image storage information corresponding to the test item ID of each read test item information is read from the screen image storage information storage unit 4 (step S2200).

  Next, in the test result comparison unit 8a, the read screen image storage information is compared (step S2300). Here, first, comparison is made between each piece of test item information with respect to the screen image before the test item is executed. And about the test item information with the same screen image before test item implementation, the screen image after test item implementation is further compared. As a result, test items having the same screen image before and after the test item are determined to be the same test result.

  Subsequently, the test result collecting unit 8b collects the test item information of the test items determined to be the same test result by the test result comparing unit 8a (step S2400). Further, the test result information is obtained by combining the aggregated result, the test item ID of the read test item information, the large classification information, the medium classification information, the small classification information, the test procedure, the test result pattern information, and the read screen image storage information. Is created and stored in the test result information storage means 8d (step S2500). The test result creation means 8 determines whether there is medium classification information that has not yet been read in the test item information storage means 5 (step S2600), and if it exists, repeats the processing from step S2100 to step S2600. If it does not exist, the process ends.

  FIG. 9 is a flowchart showing the test result pattern information adding process (step S3000 in FIG. 6) in the test result pattern information adding means 8c. First, the test result pattern information adding unit 8c reads the test result information from the test result information storage unit 8d in the middle classification information unit (step S3100). Next, the test result pattern information that matches the aggregated pattern of the read test result information is searched from the test result pattern information stored in the test result pattern information storage unit 6 (step S3200). If there is matching test result pattern information, the test result pattern name is added to the test result information (step S3300). If it does not exist, nothing is added to the test result information, or the fact that there is no matching test result pattern information is added (step S3400). Next, it is determined whether or not unprocessed middle classification information exists in the test result information storage unit 8d (step S3500). If there is, the processing from step S3100 to step S3500 is repeated. If it does not exist, the process ends.

  In the monitoring screen test support device according to the present embodiment, the test result pattern information adding unit 8c adds the test result pattern information stored in the test result pattern information storage unit 6 in advance to the test result information. However, the test result pattern information storage means 6 and the test result pattern information addition means 8c are not essential components. The monitoring screen test support apparatus according to the present embodiment has an effect of reducing the burden of visually confirming test results by aggregating the same test results. However, if the test result pattern information is added to the test result information, the test result can be confirmed more easily by focusing on the test result that does not match any pattern.

<A-3. Effect>
The monitoring screen test support apparatus according to the present embodiment includes a test item automatic execution means 7 that executes a test item that simulates an input to a monitoring target, and a monitoring screen that generates a monitoring image that is an image of the monitoring screen according to the test item. The generation means 2, the screen image storage means 3 for storing the monitoring images before and after the execution of the test items in association with the test items, and the test result creation for generating the test result information based on the monitoring images stored in the screen image storage means Means 8. The test result creating unit 8 compares the monitoring images before and after the execution of the test item among the plurality of test items, and determines that the test result is the same when both are the same, And a test result aggregating means 8b for aggregating test result information of test items having the same test result. By presenting the collected test result information to the user in this way, it is possible to reduce a burden when a person visually confirms the test result. For example, multiple test items with the same test result can be easily grasped, so it is easy to check the test items that should not have the same test result or the test items that should have the same test result if the operation is correct. .

  Further, the monitoring screen test support apparatus of the present embodiment includes a test result pattern information storage unit 6 that stores a test result pattern indicating a combination of test items having the same test result, and the test result creation unit 8 includes: When there are a plurality of test items in which the difference in the test results corresponds to the test result pattern, the test result pattern information adding means 8c for adding the test result pattern information to the test result information is provided. Confirmation of test results can be made easier by focusing on the test results that do not match the above.

<B. Second Embodiment>
<B-1. Configuration>
The monitoring screen test support device according to the first embodiment determines that the test results of the test items having the same screen images before the test item execution and the same screen images after the test item execution are the same. However, by comparing the screen images in an ambiguous manner, more test results can be collected.

  FIG. 10 shows a screen image before performing the test items A to E and a screen image after performing the test items. The monitoring screen displays a text box, and its color and the character string in it change depending on the test. As shown to Fig.10 (a), all the screen images before implementation of test item AE are the same. In the monitoring screens after the test items A, B, and D are performed, the text box color is changed to the same color. However, since the character strings in them are different from each other, according to the test result comparison means 8a of the first embodiment, these test results are determined to be non-identical.

  However, in one comparison method described later in the second embodiment, the test results of the test items A, B, and D are determined to be the same when the color of the text box is changed to the same color.

  FIG. 11 is a block diagram showing a configuration of the monitoring screen test support apparatus according to the second embodiment. In this figure, the same components as those of the monitoring screen test support apparatus of the first embodiment shown in FIG. The monitoring screen test support apparatus according to the second embodiment includes a test result ambiguity comparison unit 8e instead of the test result comparison unit 8a according to the first embodiment, and further includes an input unit 10. Other configurations are the same as those of the monitoring screen test support apparatus of the first embodiment.

  The test result ambiguity comparison unit 8e includes a comparison level setting unit 8f that sets the comparison level in the test result ambiguity comparison unit 8e based on the data input from the input unit 10. The test result ambiguous comparison unit 8e switches the test result comparison method in accordance with the comparison level set by the comparison level setting unit 8f. Below, the comparison levels 1-3 are demonstrated.

<B-2. Operation>
FIG. 12 is a flowchart showing the test result creation processing of the test result creation means 11 at the comparison level 1. The test result creation means 11 reads the screen image storage information corresponding to the test item IDs from the screen image storage information storage means 4 for the two test items to be compared (step S4100). Next, the test result ambiguity comparing means 8e determines whether or not the screen image before the test item execution is equal between the two test item information from the screen image storage information read in step S4100 (step S4200). It is determined that the test results are not identical, and the process is terminated.

  If equal in step S4200, the monitoring image before execution and the monitoring image after execution are compared for each test item, and the coordinates of the changed area are extracted (step S4300). Then, the test result ambiguity comparison unit 8e determines whether or not the coordinates of the change area are equal between the two test items (step S4400). If the coordinates of the change areas are not equal, the test result is determined to be non-identical and the process is terminated. If they are equal, it is determined that the test results are the same, and the test result aggregating means 8b collects the test results of the two test items.

  Here, the identity of the test results is determined taking into account only the difference in the coordinates of the change areas. Therefore, if the change areas are the same, even if the contents of the change are different, it is determined that the test results are the same. Therefore, the test result aggregating unit 8b creates a screen image in which the coordinates of the change area are all changed to a specific color such as red, and stores the screen image in the test result information storage unit 8d as a screen image after performing the test items after aggregation. (Step S4500).

  Next, an example of aggregation of test results according to comparison level 1 will be described with reference to FIG. FIG. 13A shows a screen image before the test items A to C are implemented and a screen image after the implementation. Here, in test items A and B, the color of the text box at the lower right of the screen changes. Test item C also differs from test items A and B in that the color of the text box at the lower right of the screen changes, but the color of the text box at the upper left also changes.

  The test result ambiguous comparison means 8e determines that the test results of the test items A and B having the same change area are the same, and collects the test results as shown in FIG. In test items A and B, the color of the text box after the test item is implemented is different, and thus the screen image obtained by changing the text box to a specific color is used as the screen image after the test item is implemented.

  Next, the comparison level 2 for determining the identity more strictly than the comparison level 1 will be described. FIG. 14 is a flowchart showing the test result creation processing of the test result creation means 11 at the comparison level 2. The test result creation means 11 reads the screen image storage information corresponding to the test item IDs from the screen image storage information storage means 4 for the two test items to be compared (step S5100). Next, from the read screen image storage information, the test result ambiguity comparing means 8e determines whether or not the test results are determined to be the same at the comparison level 1 (step S5200). When it is determined that the test results are not identical at the comparison level 1, it is similarly determined that the test results are not identical even at the comparison level 2, and the processing is terminated. When it is determined that the test results are the same at comparison level 1, for each test item, the change content between the screen image before the test item is executed and the screen image after the test item is executed, and the coordinates relating to the change content Is checked (step S5300).

  Next, the test result ambiguity comparison means 8e determines whether or not the change content having the largest number of coordinates is the same between the two test items (step S5400). Exit. If they are equal, it is determined that the test results are the same, and the test result aggregating means 8b collects the test results.

  Here, even if the number of coordinates related to the same change content is not the same, it can be determined that the test results are the same. For example, the test results are the same even if the text box color is the same and the character strings inside are different. It is judged that there is. Therefore, the test result aggregating means 8b creates a screen image in which the changed coordinates are collectively changed to the color after the change of the change content having the largest number (step S5500). For example, when the number of coordinates changed from white to gray is the largest, a screen image in which the changed coordinates are collectively changed to gray is created. The screen image created in this way is stored in the test result information storage unit 8d as a screen image after execution of the test items after aggregation.

  The processing from step S5300 to step S5500 in FIG. 14 will be described more specifically with reference to FIG. In FIG. 15A, both the screen images before the test items A and B are set as the image 1, the screen image after the test item A is set as the image 2, and the screen image after the test item B is set as the image 3. And Hereinafter, a procedure for determining the difference between the test results of the test items A and B will be described.

  First, the change content (color change pattern) is examined for each coordinate changed between the image 1 and the image 2, and the number of each change content is examined. Here, it is assumed that the number of coordinates changed from white to gray is 1124, and the number of coordinates changed from white to black is 35. Similarly, the content and number of changes between the images 1 and 3 are examined. Here, it is assumed that 1130 coordinates are changed from white to gray, and 29 coordinates are changed from white to black. Since both the test items A and B have the largest number of coordinates changed from white to gray, it is determined that the test results of the test items A and B are the same. Here, the number of coordinates changed from white to gray is not the same in the test items A and B, but it is not considered.

  In addition to comparing changes with the largest number of coordinates, the second most frequent change, or even the third largest change, if necessary, can be compared to increase the strictness of the comparison. Can be improved.

  Then, the test result collecting means 8b collects the test results of the test items A and B. Here, as shown in FIG. 15 (b), an image in which the coordinates changed by the execution of the test item A (or test item B) are collectively changed to gray is created and the test items A and B are executed. Screen image.

  Next, the comparison level 3 will be described. In the comparison level 3, when the screen images before the test item execution and the screen images after the test item execution are both the same, the test result is determined to be the same. That is, the comparison is performed by the same method as the test result comparison unit 8a of the first embodiment.

  The test result ambiguous comparison means 8e compares the test results between the test items according to any of the comparison levels 1 to 3 described above, and determines the difference. The test result aggregating unit 8b creates test result information by aggregating a plurality of test item information determined to be the same test result by the test result ambiguity comparing unit 8e for each middle classification information of the test item information, and stores the test result information. Store in means 8d.

  The input means 10 corresponds to the keyboard 16 or the mouse 17 in FIG.

  Other components and operations are the same as those in the first embodiment.

<B-3. Effect>
The monitoring screen test support apparatus according to the present embodiment includes a test result ambiguity comparison unit 8e instead of the test result comparison unit, and the test result ambiguity comparison unit 8e includes a plurality of tests having the same monitoring image before execution of the test item. Differences in test results between items are determined according to determination conditions. The determination conditions include the first condition (comparison level 1) in which the change area of the monitoring image before and after execution of the test item is the same, and the monitoring image before and after execution of the test item. Including the second condition (comparison level 2) in which the change areas are the same and the display colors of the change areas are the same, and the third condition (comparison level 3) in which the monitoring images after execution of the test items are the same. . The comparison level 3 is a comparison method similar to that of the first embodiment. However, according to the comparison level 1 and the comparison level 2, it is possible to collect more test results. So, for example, when you want to check only the rough changes as test results, such as ignoring the text in the text box and focusing only on the color change of the entire text box, you can reduce the cost of checking the test results To.

  Further, the test result ambiguous comparison means selects one of comparison level 1, comparison level 2, and comparison level 3 having different strictness of comparison as a determination condition according to external input, and tests between test items according to the comparison level. Since the difference in results is judged, the test results can be aggregated according to the user's usage.
