Description

  The present invention relates to an automatic test apparatus and an automatic test method for a mobile terminal device for testing a display screen of a mobile terminal device such as a mobile phone.

  In the function evaluation at the time of designing the mobile phone and the product performance evaluation, a test is performed to check whether the display screen displayed on the display unit included in the mobile phone is as designed (for example, (See Patent Documents 1 and 2.) Since the display screen is created under the control of the microcomputer mounted on the mobile phone, testing the display screen is essentially a function of the display screen creation function (display screen creation software) in the microcomputer. It is also to test whether or not.

  In the mobile phone testing method described in Patent Document 1, data for forming a display screen of a mobile phone (display screen data) is output from the mobile phone to the outside. A test device is connected to the mobile phone. The test apparatus inputs the display screen data output from the mobile phone, and checks whether the display screen based on the display screen data is a display screen as designed.

  In the mobile phone test method described in Patent Document 2, two mobile phones are connected to a test apparatus, and display data output from one mobile phone is used as reference data. The software of the other mobile phone is evaluated by determining whether the data on the screen matches the reference data.

Japanese Patent No. 3721135 (paragraph 0032, FIGS. 3 and 4) Japanese Patent Laying-Open No. 2003-99287 (paragraphs 0010-0012)

  In the design of a mobile phone, the content of the display screen may be partially changed due to a change in the function of the mobile phone or software update. For example, the display color may be changed, the displayed character size may be changed, the displayed sentence may be partially changed, or the displayed item may be added.

  In that case, if the test device is configured to evaluate the software of the mobile phone by comparing the display screen data input from the mobile phone with the reference data, the screen of the display screen is changed based on the function change or software update. When the contents are partially changed, it is determined that the mobile phone that has output the data on the display screen is not as designed even though it is actually as designed.

  In order to avoid such inconvenience, it is necessary to change the reference data in the test apparatus in advance when the function is changed or the software is updated. However, it is troublesome for the tester to execute the process of replacing the reference data every time there is a function change or software update of the mobile phone, and the test time increases accordingly, so the test cost increases. .

  Therefore, the present invention can reduce the test cost by minimizing the reference data change work even if the content of the display screen of the mobile terminal device changes due to the function change or software update of the mobile terminal device. An object is to provide an automatic test apparatus and an automatic test method for a portable terminal device.

  An automatic test apparatus for a mobile terminal device according to the present invention includes a reference image storage unit storing reference image data to be compared with display screen data output from the mobile terminal device, and a display screen for the mobile terminal device. The automatic test control unit that requests data output, the display screen data output from the portable terminal device, and the reference image data stored in the reference image storage unit, and a predetermined allowable range The test result comparison unit that determines whether or not the test results match and the test result comparison unit that is determined to match within the allowable range (including the case where the test result comparison unit is determined to be a complete match) is determined to pass the test. And an analysis unit.

  When the test result comparison unit determines that the display screen data output from the mobile terminal device and the reference image data do not completely match but within the allowable range, the mobile terminal device An image correction unit may be provided that updates the reference image data stored in the reference image storage unit with the display screen data output from.

  It is preferable to include an allowable range data storage unit in which difference allowable range data indicating the allowable range is stored.

  An automatic testing method for a mobile terminal device according to the present invention includes a storage step of storing in advance reference image data to be compared with display screen data output from the mobile terminal device, and a display screen data for the mobile terminal device. The request step for requesting the output is compared with the display screen data output from the mobile terminal device and the reference image data stored in the reference image storage unit, and they match within a predetermined allowable range. And a determination step for determining whether or not the test result comparing unit matches within a permissible range, and a result analysis step for passing the test.

  If it is determined in the determination step that the display screen data output from the mobile terminal device and the reference image data do not completely match but within the allowable range, output from the mobile terminal device An update step of updating the reference image data stored in the reference image storage unit with the displayed display screen data may be included.

  Preferably, the method includes a step of preliminarily storing difference allowable range data indicating the allowable range.

  According to the present invention, even if the content of the display screen of the mobile terminal device changes due to the function change or software update of the mobile terminal device, the test cost is reduced by preventing the reference data from being changed. Can do.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an example of a configuration of a mobile phone that is an example of a mobile terminal device to which an automatic test method according to the present invention is applied. Here, a mobile phone is exemplified as the mobile terminal device, but the present invention is not limited to the mobile phone, but can be applied to other mobile terminal devices such as a PDA (Personal Digital Assistants) having a display unit. .

  As shown in FIG. 1, the mobile phone 2 includes an audio output speaker 21, a display unit 22, an audio input microphone 23, an operation unit 24, a control unit 25, a memory 26, and a radio unit 27. And an antenna 29 for transmitting and receiving radio waves.

  The operation unit 24 is provided with a key button for inputting a telephone number, for example. The operation unit 24 outputs an input signal corresponding to a user operation to the control unit 25. The display unit 22 is realized by, for example, a liquid crystal display device.

  The control unit 25 is realized by, for example, a microcomputer and a peripheral circuit. The control unit 25 controls each unit provided in the mobile phone 2. Specifically, the control unit 25 controls the wireless unit 27 and other blocks according to a program stored in the memory 26.

  The radio unit 27 that transmits and receives radio signals via the antenna 29 performs signal modulation / demodulation, frequency conversion, power amplification, and the like. That is, the radio unit 27 performs a process of receiving and demodulating a radio signal via the antenna 29. The radio unit 27 performs a modulation process based on the signal output from the control unit 25 and performs a process of transmitting a radio signal via the antenna 29.

  The mobile phone 2 is further provided with an external interface (external I / F) 28. The external I / F 28 outputs display screen data created by the control unit 25 to the outside of the mobile phone 2.

  FIG. 2 is a block diagram showing the automatic test apparatus 1 together with the mobile phone 2. In FIG. 2, only the display unit 22 and the external I / F 28 are shown in the mobile phone 2.

  The automatic test apparatus 1 stores a test script storage unit 100 that stores a test script in which data indicating each test item, a test procedure, and the like are described, a reference image storage unit 200 that stores reference image data in advance, and a test result. The log storage unit 300 is provided. In addition, the automatic test apparatus 1 is provided with an allowable range data storage unit 400 in which allowable difference data indicating an allowable range of display screen data output from the mobile phone 2 with respect to a reference screen is stored in advance. As the difference allowance data determined in advance, for example, data indicating the range of display color differences, data indicating the range of character size differences, data indicating the allowable range of sentence differences, and the tolerance of the number of displayed items There is data indicating the range. However, such difference allowance data is an example, and is actually determined based on the nature of the software installed in the cellular phone 2 designed and produced.

  Further, the automatic test apparatus 1 reads the test script from the test script storage unit 100 and issues a request to output data on the display screen to the mobile phone 2 according to the test script. The display output from the mobile phone 2 The test result comparison unit 12 that compares the screen data with the corresponding reference screen data stored in the reference image storage unit 200, the comparison result of the test result comparison unit 12 is stored in the log storage unit 300, and the mobile phone 2 The result analysis unit 13 outputs the display screen data output from the data as update target data, and the image for updating the corresponding reference screen data stored in the reference image storage unit 200 with the update target data output by the result analysis unit 13 A correction unit 14 is provided.

  The automatic test apparatus 1 may be a dedicated test apparatus, or may be realized by installing automatic test software in a general information processing apparatus such as a personal computer. In addition, the mobile phone 2 is equipped with software for outputting display screen data to the outside via the external I / F 28.

Next, the operation of the automatic test apparatus 1 will be described with reference to the flowchart of FIG.
First, the automatic test control unit 11 reads a test script from the test script storage unit 100 (step S1). Then, a command for designating a test item is output to the mobile phone 2 in accordance with the description of the test script (step S2). Test items include, for example, a standby screen, a menu screen, and an e-mail mail screen.

  In the mobile phone 2, the external I / F 28 inputs a command for designating a test item from the automatic test apparatus 1. The external I / F 28 outputs a command for designating the input test item to the control unit 25. The control unit 25 creates display screen data corresponding to the input command and outputs it to the external I / F 28.

  In this embodiment, the control unit 25 in the mobile phone 2 executes a process of creating display screen data according to the test script. However, the tester actually operates the mobile phone 2 according to the test script. The display screen may be displayed on the display unit 22. Even in such a case, the control unit 25 outputs the screen data based on the display screen data to the display unit 22 and executes the process of outputting the display screen data to the external I / F 28.

  The display screen data output to the external I / F 28 may be bitmap data in a format output to a display (LCD or the like) in the display unit 22, but the display screen before the bitmap data is created. It may be data indicating the number of items, the arrangement and color of items, the text of items, and the like.

  In the mobile phone 2, the external I / F 28 outputs display screen data input from the control unit 25 to the automatic test apparatus 1. In the automatic test apparatus 1, the test result comparison unit 12 inputs display screen data. The test result comparison unit 12 compares the input display screen data with the reference image data stored in the reference image storage unit 200 and corresponding to the test item (step S4). If they match, data indicating coincidence (“OK”) is output to the result analysis unit 13 as a comparison result. If they do not match, data indicating mismatch (“NG”) is output to the result analysis unit 13 as a comparison result.

  Note that the test result comparison unit 12 immediately determines “NG” when it is detected in the process of step S4 that the display screen data output from the mobile phone 2 and the reference image data do not completely match. Don't do it. The allowable difference data stored in the allowable range data storage unit 400 is input, and if the mismatch range falls within the allowable range indicated by the allowable difference data, it is regarded as “OK”. That is, the test result comparison unit 12 compares the display screen data output from the mobile phone 2 with the reference image data stored in the reference image storage unit 200, and within a predetermined allowable range. It is determined whether or not they match.

  The result analysis unit 13 stores data indicating the comparison result in the log storage unit 300 (steps S5 and S6). If the display screen data and the reference image data do not completely match but the comparison result is regarded as “OK”, the display screen output from the mobile phone 2 is displayed together with the data indicating the test item. Data is output to the image correction unit 14.

  When the display screen data is input from the result analysis unit 13, the image correction unit 14 updates the reference image data corresponding to the test item in the reference image storage unit 200 with the display screen data (step S7). . When the next test of the mobile phone 2 is executed, an inspection is performed using the updated reference image.

  If it is determined from the test script that there are more test items (step S8), the automatic control controller 11 returns to step S1. In addition, you may return to step S2. In any case, the processes in steps S2 to S7 are repeatedly executed until the tests for all the test items are completed.

  Here, for each item, when the display screen data does not match the reference image data, but the mismatch range is within the allowable range, the reference image data is updated with the display screen data. However, after executing the test for all the test items and storing the data indicating the comparison result in the log storage unit 300, the result analysis unit 13 reads the data stored in the log storage unit 300 and sets it to “OK”. The reference image data corresponding to the test item in the reference image storage unit 200 may be updated with the data of each display screen corresponding to the respective data. Even in this case, it is preferable to update the reference image data only for the data in which the display screen data and the reference image data do not completely match but the comparison result is regarded as “OK”.

  As described above, in this embodiment, when the test related to the display screen of the mobile phone 2 is executed using the automatic test apparatus 1, the display screen data and the reference image data input from the mobile phone 2 When the values do not match, if the degree of mismatch is within the allowable range indicated by the difference allowable data stored in advance in the allowable range data storage unit 400, the data on the display screen and the reference image data are considered to match. That is, the test is not rejected. Further, when it is determined that the display screen data and the reference image data match, the reference image data is updated with the display screen data input from the mobile phone 2.

  Thus, for example, when a large number of mobile phones 2 are sequentially tested using the automatic test apparatus 1, when the contents of the display screen are partially changed due to a change in the functions of the mobile phone or software update, etc. It is possible to prevent a situation in which a test failure occurs and a series of tests are interrupted. That is, a series of tests can be continued. Further, since the reference image data is updated with the display screen data input from the mobile phone 2, the reference data is automatically replaced with the latest data without changing the reference data in the test apparatus in advance.

  The present invention is suitably applied when testing a portable terminal device having a display screen. In particular, it is useful for testing a portable terminal device in which minor specification changes are likely to occur.

It is a block diagram which shows an example of a structure of the mobile telephone to which the automatic test method by this invention is applied. It is a block diagram which shows an automatic test apparatus with a mobile telephone. It is a flowchart which shows an automatic test method.
