[0030] A test process recording and playback method, the method comprising the method comprising selecting a test process recording by an industrial computer, loading a test scene; interpreting the test scene and displaying it to the tester; after the tester loads the pre-defined product pin information through the supporting software of the industrial computer, the artificial interaction module displays the simulation state information of the pin, and the tester clicks the pin on the artificial interaction module to switch it to an effective state, and the operation information is recorded and automatically stored in the background in the use case recording module, at the same time, the operation information is transmitted to the simulation switch component through the artificial interaction module and the component control module in turn, the simulation switch component converts the information into high and low voltage, the voltage is transmitted to the test product through the connecting component, the test product outputs a high signal to the simulation load component, the simulation load outputs a signal to the artificial interaction module, and the icon of the product is lit, then the tester clicks the product pin again to switch it to an ineffective state, and the information is transmitted to the product in the above manner, and the icon of the product is extinguished; after the test is completed, the tester confirms on the artificial interaction module that the test scene passes the test, which means that the temporarily stored information is valid, and the information is stored in the file in a human language, that is, a test case file is generated;

[0031] When the above test scene function needs to be repeatedly tested, the tester loads the recorded test case file in the industrial computer and clicks start playback, the use case playback module parses the information stored in the file and transmits it to the simulation switch component through the component control module; the simulation switch component converts the information into high and low voltage, and the voltage is transmitted to the test product through the connecting component, and waits for the tester to confirm whether the product passes the test or not through the artificial interaction module; the result of the confirmation is stored in the test case file again through the use case recording module, so that the above test scene function is repeatedly tested.

[0032] The operation information includes clicking the switch and sending data; the sending data realizes the bidirectional communication between the artificial interaction module and the product under test through the signal sending and receiving component.

[0033] Embodiment: using the device, the high beam function test process recording and playback of the automobile instrument product is completed.

[0034] The high beam function requirement is that when the instrument ON fire pin is effective and the high beam pin is effective, the high beam icon is lit.

[0035] The logic can be divided into the following test scenes:

[0036] Test scene 1: effective and ineffective of the high beam pin, control the high beam icon to light up and extinguish.

[0037] Test scene 2: effective and ineffective of the ON fire pin, control the high beam icon to light up and extinguish.

[0038] For scene 1, the tester loads the pre-defined product pin information on the industrial computer, and the simulation state information of the ON fire pin and the high beam lamp pin is displayed on the artificial interaction module. The tester clicks the ON fire pin and the high beam lamp pin on the artificial interaction module to switch to the effective state, and the operation information is recorded. The operation information is automatically stored in the use case recording module in the background, and is transmitted to the simulation switch assembly through the artificial interaction module and the component control module.

At this time, the product without problems outputs a high-level signal to the simulation load assembly, and the simulation load assembly transmits the output to the artificial interaction module, and the high beam lamp icon is lit. Then the tester clicks the high beam lamp pin to switch to the invalid state, and the information is transmitted to the product in the same way. The high beam lamp icon is extinguished. The scene 1 test is completed, and the tester confirms that the scene 1 test is passed on the artificial interaction module, which means that the stored information is valid, and the information is stored in the file in human language, that is, the test case file is generated.

[0039] The similar steps complete the scene 2 test process and recording. The tester determines that the test is completed, and stops the software.

[0040] When the high beam lamp function of the instrument needs to be repeatedly tested, the tester loads the recorded test case file in the industrial computer and clicks start playback. The use case playback module parses the information stored in the file and transmits it to the simulation switch assembly through the component control module. The simulation switch assembly converts the information into high and low voltage, and the voltage is transmitted to the test product through the connection assembly. The tester waits for the product to pass or not pass the test through the artificial interaction module. The result is stored in the test case file again through the use case recording module, so as to complete the repeated test of the high beam lamp function.

The above example only describes one function of the instrument product, and there are more than 200 functions in the actual product. The manual repeated test takes a long time, and the efficiency can be improved obviously by using the device.

[0042] The application provides a test process recording and playback device for artificial testing, recording test process, and playing back test process of products.The device adopts automatic acquisition and recording technology, supports artificial testing, artificial test process recording and playback, selects test process recording, loads test scene, interprets test scene and displays it to testers, acquires tester operation process (clicking switch, interactive data, etc.), determines that the tester ends recording, stores process data into test case file, selects test process playback when testing the same scene, loads test case, interprets process data, uses process data to control switch, interactive data, etc., and waits for testers to confirm test results, and determines that the test case execution is completed, and the playback process is stopped.The application can record and playback test process, realizes automatic testing, improves test efficiency, and has high practical value.The artificial testing can record test steps such as switch simulation, load simulation, signal sending and receiving into a form convenient for artificial reading, store them in artificial test cases, form automatic test cases, and support playback of test cases in subsequent regression testing, and realize automatic testing.

[0047] The device adopts an automatic test script to store technology in human language (the automatic test is executed based on a computer, generally a computer language such as C language, Python, etc. is used. The matching software developed combines with years of test work experience, researches the test cases used by manual execution, designs a mapping relationship between human language and component control code, and thus identifies the cases prepared in human language.). The generated automatic test script is directly stored in human language instead of machine language or other programming languages, which is convenient for reading and understanding. Meanwhile, the machine can also identify the stored human language and replay the test process.

[0048] Meanwhile, the device adopts an automatic test script and manual test case relationship mapping technology. The technology can map the automatic test script and the manual test case together to form a corresponding relationship, reduces the repeated preparation of the same information, and improves the reuse of the labor achievements of the test personnel. The mapping technology can also make the preparation of the automatic test script iterate with the iterative development of the product, and the test personnel can maintain the manual test case and the automatic test script at the same time, so that the confusion relationship caused by the separate maintenance of the automatic test script after the change of the manual test case is avoided, and the iterative development is better applied.

After the tester loads predefined product pin information using the industrial-grade computer's accompanying software, the human interaction module displays the simulated status information of the pins. The tester clicks on the pin in the human interaction module to switch it to an active state.
