Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a method, a device and equipment for testing vehicle-mounted power supply application software, aiming at the problem that the software needs to be automatically tested on a target board because the development cycle of vehicle-mounted embedded software is shorter than that of hardware.
As shown in fig. 1, an embodiment of the present invention provides a method for testing vehicle power application software, where the method includes:
and step 12, executing the test case on the target board, testing the source code, and obtaining a test report of the vehicle-mounted power supply application software.
It should be noted that, by automatically testing the vehicle-mounted power supply application software on the target board and automatically generating the test report, the test time can be effectively shortened, so that the development period of the software is shortened, and compared with a manual test mode, the labor cost can be effectively reduced.
Specifically, the number of the test cases is at least one, preferably, the test cases CAN be edited by a Python language, while the application software is developed, a test engineer CAN develop a test executable file by using the Python language, and the test engineer connects the upper computer and the target board through Controller Area Network (CAN) communication to complete an automated test and automatically generate a test report.
Wherein, in step 11, determining a source code for testing the vehicle power application software according to the vehicle power application software to be tested and an input/output interface document applied to an input/output interface of a system running the vehicle power application software, includes:
acquiring an initial code of the vehicle-mounted power supply application software;
and determining a source code for testing the vehicle-mounted power supply application software according to the initial code and the input/output interface document.
In step 11, determining a test case according to the vehicle-mounted power application software to be tested and the input/output interface document applied to the input/output interface of the vehicle-mounted power application software includes:
acquiring the test requirement of the vehicle-mounted power supply application software;
and determining the test case according to the test requirement, the input/output interface document and the source code of the vehicle-mounted power supply application software test. Wherein the test case includes an expected output for executing the test case.
It should be noted that, in the actual application process of the vehicle power application software, there are various analog sampling data or hardware I/O port sampling data, and there are special situations such as communication failure, program run-off failure, watchdog abnormality, and the vehicle power application software also analyzes and processes the sampling data and outputs PWM or I/O port. Therefore, the vehicle power supply application software needs to simulate the above interaction information in the test process.
Wherein each analog sample in the source code CAN be simulated by data received from the fixed CAN ID; each hardware I/O port samples, also simulated by data received from a fixed CAN ID; some communication failures, program run-off failures, watchdog anomalies, are simulated by flag bits received from the fixed CAN ID; the PWM and I/O ports output from the source code are analyzed by transmitting data from the fixed CAN ID to determine whether to output the PWM and enable the I/O ports. And the newly added CAN ID and the analysis interface are supplemented to the input and output interface document.
It should be noted that before the software test is performed, it is necessary to determine whether the source code is updated, and if the source code is updated, the test case needs to be modified correspondingly to verify that the updated source code does not affect the implementation of the software function. Prior to step 12, the method further comprises:
checking whether the source code of the vehicle-mounted power supply application software test needs to be modified;
and when the source code of the vehicle-mounted power supply application software test needs to be modified, modifying the test case according to the modified source code.
It should be further noted that, in order to locate a certain test case that fails the test, the number of test cases that pass all tests and the number of test cases that fail the test are counted, before step 12, the method further includes:
numbering the test cases and expected outputs corresponding to the test cases to obtain the numbers of the test cases;
specifically, after the test environment is built, the test cases are read one by one, input data are sent to a target board through Controller Area Network (CAN) communication, and after the test cases to be tested are executed, output data in CAN IDs are read, so that the test results of the test cases are judged. Thus, said step 12, comprises:
sequentially executing the test cases on a target board according to the serial numbers, and testing the source codes;
and obtaining a test report of the vehicle-mounted power supply application software according to the test result of each test case.
It should be noted that, the step of executing the test case and testing the source code includes:
inputting input data for testing and the test case to a target board through a CAN controller local area network;
executing the test case on the target board, and acquiring output data of the CAN output for executing the test case;
comparing the output data to expected outputs of the test case;
and if the output data is inconsistent with the expected output, storing the serial number of the test case to the test report.
It should be noted that, after a test case is executed, the analyzed output data is compared with the expected output, and if the analyzed output data is inconsistent with the expected output, the test case fails, and in order to not affect the execution of other subsequent test cases, the fault caused by the test case failure needs to be cleared.
It should be further noted that after all test cases are executed, the number of all pass items and fail items in the test report is counted, and the test case number of the fail item is included, so as to facilitate the problem location.
