Description

  The present invention relates to a test system, a test method, and a test program.

  In a next-generation DVD (Digital Versatile Disc) playback device, an image functioning as a button (hereinafter referred to as a “button image”) can be displayed on the screen being played back. Here, the button image is displayed based on the button layout on the remote controller (hereinafter referred to as “remote control”) or the front panel, and the function of each button such as “play”, “stop” or “fast forward” is displayed. There are images that guide the user, images that are not displayed based on a remote controller or a front panel button layout that shows each of the chapters to be selected, and the like.

The user can play back the DVD by pressing a button on the remote control or front panel corresponding to the button image indicating “play”. Further, a chapter can be selected by selecting an arbitrary button image from the button images indicating the respective chapters by pressing a selection button on the remote controller or the front panel, and further pressing a confirm button.

  In this way, when the user presses a button on the remote control or the front panel, the next-generation DVD playback device displays the color of the button image corresponding to the pressed button or the color of the selected button image. It is selected by changing the display to indicate that it has been pressed, or by selecting a button image that is different from the currently selected button image, and canceling the selection display of the currently selected button image. Control to change the button image.

When developing such a button image display function when developing software to be implemented on the next-generation DVD player, the tester manually operates the button and visually confirms the change in the button image display. The result is recorded manually. For this reason, when testing button operations of various patterns, a large number of man-hours are required, which causes an increase in cost.
Therefore, there is a need for a system that can easily perform such a button image display function test without human intervention.

It consists of a plunger unit, a computer that controls the operation of the plunger unit, determines whether the display content of the LCD panel corresponding to this operation control is correct, and a monitor that serves as an image display means based on a signal from the computer. The

  Here, the processing of this inspection apparatus will be briefly described. First, according to a scenario created in advance, the key button of the cellular phone is pressed by the release. Next, the screen of the LCD panel after the key button is pressed is imaged by the camera. The captured screen is subjected to processing such as correction and conversion in a computer, and is compared with an expected value image prepared in advance. Then, it is determined from the comparison result whether or not the mobile phone has performed as expected. The inspection apparatus executes the above processing for the number of commands included in the scenario.

  However, since the technique described in Patent Document 1 requires one expected value image for each button operation, if the amount of operation in the test increases, expected value data with a huge amount of data is required. End up.

Note that Patent Document 2 automatically refers to an output screen output by an application program in response to an arbitrary input event, and automatically compares the application data by comparing reference data including image data that is an expected value with reference results. A technology that enables highly reliable evaluation even when there is a blink cursor or a character moving on the screen by referring to the output screen according to the timing at which the data update of the output screen is confirmed in the simulation device to be evaluated. It is disclosed.
However, in the technique described in Patent Document 2, it is necessary to prepare reference data including image data that is an expected value so as to correspond to each input event. There is a problem that the amount increases.

Further, Patent Document 3 generates image data of a display image displayed by a test target device based on information stored in an expected value DB, according to a test signal generated based on a scenario including a series of test data. A technique for verifying whether or not a test target apparatus is operating normally by comparing it with image data of a reference image that has been performed is disclosed.
However, in the technique described in Patent Document 3, since it is necessary to prepare buttons and character strings included in the generated reference image in the expected value DB as image data, the expected value data amount required in the test is large. There is a problem of increasing.

Then, the control unit 22 of the disk reproducing device 2 outputs an image signal obtained by changing an image to the display device 5 in accordance with the acquired operation signal. The front panel 3 and the remote controller 4 function as an operation unit.

  The test host PC 1 includes a test table storage unit 11, a test execution program storage unit 12, a test result storage unit 13, a result determination unit 14, an image event acquisition unit 15, and a test target execution control unit 16. The test host PC 1 has information for testing, and executes a test for the disc playback apparatus 2.

The test table storage unit 11 stores a test table in which button operations to be executed in the test of the disc playback device 2 are determined in advance. The test table corresponds to test information.
The test execution program storage unit 12 stores a test execution program that is downloaded to the test execution unit 21 of the disc playback apparatus 2 and executed.
The test result storage unit 13 stores the test result created by the result determination unit 14. The test executor can confirm the pass / fail of the test by referring to the test result stored in the test result storage unit 13.

The result determination unit 14 changes the button image corresponding to the button operation based on the test table used in the test of the disc player 2 and the image event information generated when the button operation is executed according to the used test table. It is determined whether or not has occurred. Then, the determination result is generated as a test result and stored in the test result storage unit 13.
The image event acquisition unit 15 acquires the image event information output from the image event output unit 221 and outputs the acquired image event information to the result determination unit 14.
The test target execution control unit 16 transmits the test table stored in the test table storage unit 11 and the test execution program stored in the test execution program storage unit 12 to the test execution unit 21 of the disc playback apparatus 2.
Note that the configuration of the apparatus that functions as the test host PC is not limited to the configuration in the present embodiment as long as the function corresponding to the above-described components is included. For example, the above-described components may be distributed and provided in each of a plurality of information processing devices such as a PC or a server, and the information processing device including the above-described components is not limited to a PC.

The disc playback apparatus 2 includes a control unit 22 having a test execution unit 21 and an image event output unit 221. The disc playback apparatus 2 is a test target apparatus that is tested by the test host PC 1. In addition to the original functions, the disc playback device 2 is provided with a test execution unit 21 and an image event output unit 221 that execute processing for a test.
In the present embodiment, a case where a disk playback device is applied as the test target device is illustrated, but an image playback device including a memory other than a disk or a storage unit such as an HDD (Hard Disk Drive) may also be used. Can be applied.

The test execution unit 21 executes a button operation based on the test table. The test execution unit 21 does not actually execute the button operation of the front panel 3 or the remote controller 4, but performs processing for the control unit 22 so that the control unit 22 executes image signal generation processing corresponding to the button operation. Execute. Note that the test execution unit 21 may be provided outside the disc playback device 2 and execute a button operation by actually pressing a button on the front panel 3 or the remote controller 4.
In addition, the test execution unit 21 acquires the image event information output from the image event output unit 221 and performs processing to output to the image event acquisition unit 15.
Note that the processing in the test execution unit 21 is performed by a test execution program downloaded from the test execution program storage unit 12 and executed.

The control unit 22 controls the disc playback device 2 according to button operations. For example, in response to a button operation, processing for outputting a playback image and displaying a button image is performed.
When the control unit 22 changes the button image, the image event output unit 221 specifies the time when the button image is changed and the operation number corresponding to the change of the button image, and the image event information including the specified time and the operation number Is generated. In addition, the image event output unit 221 outputs the generated image event information to the test execution unit 21.

Next, the processing of the test system will be described using the flowchart shown in FIG.
First, the test target execution control unit 16 acquires a test table from the test table storage unit 11 and acquires a test execution program from the test execution program storage unit 12. Then, the test target execution control unit 16 transmits the acquired test table and test execution program to the test execution unit 21 of the disk playback device 2 (S301). The test execution unit 21 executes the subsequent processing by executing the test execution program.
The test execution program may be stored in advance in the test execution unit 21 so that the test execution program storage unit 12 is not provided.

First, the test execution unit 21 reads information for one row from the test table (S302).
Here, FIG. 3 illustrates a test table. The test table includes an item number for one button operation, an operation time indicating a time for performing the button operation, and an operation number for specifying the button operation.

“Item number” indicates the order in which button operations are performed.
“Operation time” indicates the time when the button operation is performed with the test start time set to “0:00”.
The “operation number” indicates what button operation is performed. For example, a button operation such as pressing a button such as “Play”, “Stop”, or “Fast-forward”, a button that changes a selected chapter, or a button that confirms the current selection is uniquely identified. Information that can be.

Next, the test execution unit 21 executes the button operation corresponding to the acquired operation number at the operation time acquired in step S301 (S303). In the processing in step S <b> 303, the test execution unit 21 artificially generates an operation signal corresponding to the operation number, and outputs the generated operation signal to the control unit 22. And the control part 22 acquires the operation signal output from the test execution part 21, and performs the process corresponding to the acquired operation signal. By this processing, the control unit 22 generates an image signal that is information for displaying an image changed according to the operation signal, and outputs the generated image signal to the display device 5.
Note that the test execution unit 21 may be included in the test host PC 1 and the operation signal may be transmitted from the test host PC 1 to the control unit 22 of the disc reproducing apparatus 2.
Alternatively, the test execution unit 21 may be included in the control unit 22 to directly start the process corresponding to the operation number.

Next, the image event output unit 221 generates image event information when a change occurs in the button image (S304, S305).
Here, FIG. 4 illustrates image event information.
“Time when button image changed” indicates the time when the button image has changed when the test start time is set to “0:00”.
The “operation number corresponding to a change in button image” is an operation number corresponding to a button operation that causes a change in the generated button image.

Details of the processing in step S305 will be described with reference to FIG. FIG. 5 is a diagram showing details of the disc playback apparatus 2.
The data generation processing unit 222 generates image data that is a source of an image signal indicating what kind of image is displayed based on the operation signal. The image data includes, for example, information that can determine which button image is displayed as pressed, which button image is selected and displayed, and the like. The data generation processing unit 222 outputs the generated image data to the image output unit 223 and the image event output unit 221.
The image output unit 223 generates an image signal based on the image data acquired from the data generation processing unit 222 and outputs the generated image signal to the display device 5.
The image event output unit 221 generates image event information based on the image data acquired from the data generation processing unit 222. The image event output unit 221 detects the change of the button image by acquiring and referring to the image data, and specifies the operation number from the content of the change of the button image. Further, the time when the image data is acquired is specified. Then, the image event output unit 221 generates image event information including the identified operation number and operation time. The image event output unit 221 outputs the generated image event information to the test execution unit 21.

Next, the test execution unit 21 transmits the acquired image event information to the image event acquisition unit 15 of the test host PC1. Then, the image event acquisition unit 15 acquires the image event information transmitted from the test execution unit 21 (S306).
Next, the test execution unit 21 determines whether there is a continuation in the test table (S307).
If there is a continuation, the process of step S302 is executed to read the next line from the test table. Then, the subsequent processing is executed in the same manner.
When there is no continuation, the result determination unit 14 determines the test result (S308). By this processing, the result determination unit 14 acquires a test table from the test table storage unit 11 and acquires image event information from the image event acquisition unit 15. Then, a test result is generated based on the acquired test table and image event information.

Here, FIG. 6 illustrates test results generated based on the test table shown in FIG. 3 and the image event information shown in FIG.
Since “item number”, “operation time”, and “operation number” are the same as those in the test table, description thereof is omitted.
“Button image change” indicates whether or not a button image change has occurred.
“Result” indicates whether or not a button image change corresponding to the button operation has occurred.

  When the result is “OK”, it indicates that a change in the button image corresponding to the button operation has occurred. “OK” when there is image event information including “time when button image changed” and “operation number corresponding to change in button image” matching “operation time” and “operation number” included in the test table Become.

When the result is “NG”, it indicates that no change in the button image corresponding to the button operation has occurred. For example, if there is no image event information corresponding to the test table item, there is image event information corresponding to the test table item, but "operation time" and "time when button image changed" or "operation number" and " It is “NG” when the operation number “corresponding to the button image change” does not match.
As a result, the button image does not change according to the button operation, the button image changes according to the button operation, but the button image does not change corresponding to the button operation, the button image changes according to the button operation. However, it is possible to detect a failure such as an abnormal time taken until the button image is displayed.

It should be noted that it takes a long time from the time when the button operation is performed to the time when the image data is output by this button operation until the generation of the image event information, and a disc playback device in which a certain time elapses is tested. In this case, “NG” may be determined when a time difference exceeding the predetermined time occurs.
Also, the information corresponding to the “operation number corresponding to the button image change” in the image event information does not have to match the “operation number” in the test table, and the information of the button image corresponding to the executed button operation. Any information that can determine whether or not a change has occurred is not limited to that exemplified in the present embodiment.
The result determination unit 14 stores the test result generated in this way in the test result storage unit 13 (S309).

As described above, according to the present embodiment, a change in the button image is detected, and the test is performed based on the image event information indicating the change in the button image and the information included in the test table that is an expected value. Generate results. Therefore, the expected value data required for one button operation is only information on the operation time and operation number for one line of the test table, and it is not necessary to prepare an expected value image. Can be reduced.
Further, even if the number of button operations executed in the test increases, the expected value data amount does not increase significantly.
