The present invention will now be described in detail with reference to the accompanying drawings. Hereinafter, a repeated description, a known function that may obscure the gist of the present invention, and a detailed description of the configuration will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

Hereinafter, an electronic equipment input / output signal and SW performance testing apparatus according to an embodiment of the present invention will be described.

1 is a block diagram of an electronic equipment input / output signal and SW performance testing apparatus 100 according to an embodiment of the present invention. As described above, the electronic device input / output signal and SW performance testing apparatus 100 according to the embodiment of the present invention is not limited to a script method which is complicated to be created by the user, Is carried out. In addition, the electronic device input / output signal and SW performance testing apparatus 100 according to an embodiment of the present invention may be configured such that once a user manually performs a series of testing procedures through GUI, After the correction / supplement, the test can be performed automatically for the regression test of the same item.

The apparatus includes a real-time simulator 110, a screen generator 120, a scenario setting unit 130, and a controller (not shown) 140). Here, the above-described configurations divide the respective components into functions in order to facilitate understanding of the test apparatus 100 according to an embodiment of the present invention, and may actually be implemented through a single processing device.

The real-time simulation unit 110 functions to generate a plurality of interworking equipment models 112, 113, and 114 interlocked with the test target equipment 10. The real-time simulator 110 generates an output signal according to an operation scenario set in accordance with the control of the controller 140 as described below, and outputs it to the test target device 110 through the external communication module 111 The test of the test object apparatus 10 can be performed. The output signals generated by the plurality of interlocking equipment models 112, 113, and 114 are converted into output signals generated by the actual interlocking equipment and transmitted to the test target equipment 10.

The screen generating unit 120 generates a test item selection screen to receive a plurality of test items for the test target equipment 10 from a user. Here, an example of the test item selection screen generated through the screen generating unit 120 is shown in FIG. 2, a test item selection screen may be generated including test items for each of a plurality of interworking equipment models 112, 113, 114, such that a user may select one of the interworking equipment models 112, 113, 114 At least one of the items existing in the test item selection screen may be selected equally or differently.

For example, the user can control the first interlocking equipment model to output the C output signal and the E output signal through the test item selection screen generated through the screen generating unit 120. [ Similarly, the user can control to receive either the input signal or the bar input signal among the signals inputted through the first interlocking equipment model through the above-described test item selection screen. In this way, the user can input test items in the same manner for each interlocking equipment. That is, the user can conveniently perform a desired setting for each of the interlocking equipment models through the test item selection screen (that is, by the GUI method).

The scenario setting unit 130 sets an operation scenario for a plurality of interworking equipment models based on a plurality of test items input from a user. Of course, the scenario setting unit 130 may set the operation scenarios for a plurality of interworking equipment models according to the order of test items set by the user.

For example, when the user sequentially selects the first test item, the second test item and the third test item with respect to one interlocking equipment model, the scenario setting unit 130 sets the first test item, And the test for the third test item are sequentially performed. For example, in the example of FIG. 2, when the user selects the test item so as to output the C output signal and the E output signal in the first interlocking equipment model and receive the input signal and the bar input signal, The controller 130 may output the C output signal and the E output signal in the first interworking equipment model and generate an operation scenario to receive the input signal and the bar input signal among the signals output from the test target equipment.

The control unit 140 applies the output signals of the plurality of interlocking equipment models to the test target equipment in accordance with the operation scenario, collects some of the signals output from the test target equipment as input signals according to the operation scenario, Thereby performing a test on the device under test.

At this time, the user checks the output signals (i.e., the input signals input to the respective interlocking equipment models) output from the test target equipment, and determines whether the test target equipment outputs correct values, that is, have. If it is determined that the test is successful, the user can input test result information to the control unit 140 through a separate input process, and the controller 140 can determine whether the test is successful have. Of course, the determination of the success or failure of the test may be automatically performed by the control unit 140 as described below when the preset information about the normal range of the output signal is built in the storage unit in advance.

If it is determined that the test apparatus 10 has been successfully tested, the control unit 140 stores the operation scenario confirmed to be successful by the user in the storage unit 150 as a macro test item, An identifier may be assigned to the item. That is, the macro test item can be used when there is a possibility to perform the same process later on the test that has been successfully performed, and the identifier for the macro test item can be generated so that the user can be easily identified. Of course, such identifiers may be input from a user.

Accordingly, when generating the test item selection screen, the screen generator 120 determines whether a macro test item exists by searching the storage unit 150. If the macro test item exists, the screen generator 120 includes a macro test item The test item selection screen can be generated. In this case, the user can perform the same test procedure by selecting a macro test item, and by setting the number of repetitions of the macro test item through the input unit, the same test can be repeated so as to be repeated according to the set repetition number from the user.

Also, in the above description, when it is determined that the test is successful, the normal judgment value for the test may be stored in the storage unit 150. [ Accordingly, it is possible to determine whether or not the first test is successful by inputting the user. However, the test using the macro test item is performed by analyzing the input signal inputted to each equipment interworking model in the control unit 140, A method of determining the success or failure of the test may be adopted.

In addition, when the above-described testing process is completed, the screen generating unit 120 may generate a test result screen, that is, a test success result screen or a test failure result screen according to the success or failure of the test target equipment.

FIG. 3 is a flowchart of an electronic equipment input / output signal and SW performance test method according to an embodiment of the present invention. As described above, according to the embodiment of the present invention, the input / output signal and the SW performance test method of the electronic equipment are not tested in a cumbersome script method to be created by the user. . In addition, the electronic device input / output signal and SW performance test method according to the embodiment of the present invention can be implemented by manually adjusting a test procedure through GUI once, , The test can be automatically performed for the repeated test of the same item. 3, an explanation will be given of an electronic equipment input / output signal and SW performance test method according to an embodiment of the present invention. In addition, the description that is overlapped with the above-mentioned parts is omitted in the following.

Step S110 is a step of generating a plurality of interworking equipment models linked to the test target equipment by the real-time simulator. As described above, step S110 is a step of generating an interworking equipment model corresponding to a plurality of interworking equipment to determine the operation of the equipment to be tested according to the operation of the plurality of interworking equipment.

Step S120 is a step of generating a test item selection screen to receive a plurality of test items for the test target equipment from the user. Here, the test item selection screen may include at least one test item for each of a plurality of interworking equipment models, and an example of the test item selection screen has been described in detail with reference to FIG. 2. Therefore, redundant description will be omitted.

Step S130 is a step of receiving test items from the user. That is, the user can select a desired test item out of a plurality of test items displayed on the test item selection screen, and the selection can be made differently or the same for each of the interlocking equipment models.

In operation S140, the scenario setting unit sets the operation scenarios for the plurality of interworking equipment models based on the plurality of test items input by the user. Here, the step S140 may be performed in consideration of the order of test items set by the user.

 In operation S150, the control unit controls operations of the plurality of interworking equipment models according to the operation scenario. That is, in step S150, the plurality of interworking equipment models generate output signals according to the operation scenarios set in step S140, and the generated output signals are transmitted to the test target equipment.

Step S160 is a step of judging whether the test has been successfully performed. As described above, if the test items input from step S130 are general test items other than the macro test items, a procedure for confirming the test success through the user is required. Accordingly, in step S160, the user can confirm the input signals input to each interlocking equipment model according to the test, and input the test result information through the input based on the confirmation result of the input signal.

As a result of the determination in step S160, if the test is successfully performed, the control is transferred to step S170, and the operation scenario generated in step S140 is stored as a macro test item in the storage unit. Here, in the process of storing the macro test items, the values of the input signals input to each of the interlocking equipment models when the test is successful can be stored together as a normal judgment value in the storage unit. This normal decision value can be used in the control itself, not in the user, as described above, to determine the success of the test. In addition, the macro test items stored in the storage unit in step S170 may be given a unique identifier for identification of each test item. Here, it is also conceivable that the identifier is assigned according to the input of the user.

Step S180 is a step of generating a test result screen by the screen generator and informing the user of the test result screen.

In step S190, it is determined whether the test is terminated by the control unit. If a command for ending the test is inputted, control is transferred to the end block. Otherwise, control is transferred to step S130, and the above-described procedure can be performed again.

In addition, although it has been mentioned in the above description that step S180 is performed only when the test is successful, this is only an example. If it is determined in step S160 that the test has failed, control is transferred to step S180 to generate a test failure result screen Do.

As described above, the test apparatus and method according to an exemplary embodiment of the present invention can perform testing of a test target apparatus based on a GUI, and can be stored as a macro test item in the case of an already performed operation scenario, So that it is possible to obtain a desired image. Accordingly, according to the test apparatus and method according to the embodiment of the present invention, the test can be conveniently performed without implementing a script for the test.

When the macro test item is generated as described above, the user can perform the test using the macro test item through a series of processes shown in FIG.

That is, when the macro test items other than the general test items are input through step S230, the operation scenarios can be set based on the macro test items based on the repetition times set by the user in step S240.

Thereafter, in step S250, the operation of the interlocking equipment model is controlled according to the operation scenario based on the repetition times set by the user. In step S260, the control unit determines whether the test is successful. As described with reference to FIG. 3, in the case of the general test item, the test using the macro test item can be made by the control part using the normal judgment value stored in advance in the storage part, unlike the case where the user directly verifies the test success. have.

When the test is completed, control passes to step S280, and a test result screen is generated. In FIG. 4, the test result screen is generated only when the test is successful. However, the test result screen is generated only according to the success or failure of the test, and the test result screen or the test failure result screen may be generated and provided to the user .
