[0036] The following is a detailed description of an intelligent cockpit automatic testing system and testing method of the present invention.

[0037] The present invention provides an intelligent cockpit automated testing system including a test host 1, a server 2, a test slave 3, a test device 4 and an intelligent cockpit controller 5. The test host 1 is a computer for controlling the start of the intelligent cockpit automated test. The server 2 is a JENKINS automated server for controlling the progress of the intelligent cockpit automated test. Specifically, the server 2 obtains the software upgrade package from the gitlab online code repository software and inputs it to the test slave 3. At the same time, after the software upgrade of the intelligent cockpit controller 5 is completed, the test tasks are distributed to each test slave.

[0038] The test slave 3 uses a computer to control the test equipment 4 to test the smart cockpit controller 5. The RF automated test framework in the test slave 3 schedules test resources from the database of the server 2, outputs test instructions to the smart cockpit controller 5, and controls the test equipment 4 to test the smart cockpit. There are three test slaves 3 in the embodiment of the present invention. The first test slave detects the smart cockpit controller 5, the second test slave controls the programmable power supply, and the third test slave controls the bus test tool (CANOE). The three test slaves of the present invention work together to detect the smart cockpit controller 5, which improves the efficiency of the detection. At the same time, the division of labor can reduce the occurrence rate of failures.

[0039] The test equipment 4 includes a programmable power supply and a bus test tool (CANOE). The programmable power supply is used to generate an offset voltage and simulate different voltage parameters. The bus test tool (CANOE) is used to simulate the automobile bus system and detect the input and output interfaces of the intelligent cockpit controller 5. The intelligent cockpit controller 5 includes a microprocessor (MPU), a microcontroller (MCU) and a processor R5. The models of the microprocessor (MPU), the microcontroller (MCU) and the processor R5 are NXP NXPS32K automobile MCU, Texas Instruments Jacinto 7 model MPU, Cortex TM -R5 processor.

[0040] The output end of the test host 1 is connected to the input end of the server 2 via a wireless network, and the output end of the server 2 is respectively connected to the input ends of the three test slaves via a wireless network. The first test slave is connected to the intelligent cockpit controller 5 via a USB universal serial bus, the output end of the second test slave is connected to the input end of the programmable power supply via an Rs232 bus, and the output end of the third test slave is connected to the input end of the bus test tool (CANOE) via an Rs232 bus. The output ends of the programmable power supply and the bus test tool (CANOE) are respectively connected to the input end of the intelligent cockpit controller 5, and the output end of the intelligent cockpit controller 5 is connected to the input end of the first test slave.

[0041] The specific steps of an intelligent cockpit automatic testing method of the present invention are:

[0042] Test host 1 inputs the test start command to the JENKINS automation server, the JENKINS automation server obtains the software upgrade package from the gitlab online code warehouse software, the JENKINS automation server creates an automated test task, and performs daily builds. Specifically, the test code of the day is compiled and built and an automated smoke test is performed to detect the basic functions of the test code to ensure that the basic functions and processes of the test code can be run. The present invention detects the basic functions of the test code through daily builds, which can detect problems as early as possible and reduce the cost of solving problems.

[0043] After the daily build is completed, the JENKINS automation server transmits the software upgrade package to the test slave 3, and the test slave 3 then transmits the software upgrade package to the smart cockpit controller 5. The microprocessor (MPU), microcontroller (MCU) and processor R5 in the smart cockpit controller 5 are upgraded. After the software of the smart cockpit controller 5 is upgraded, the JENKINS automation server assigns the test task to the test slave 3. The RF automated test framework in the test slave 3 calls the automated test script in the database of the server 2 to test the smart cockpit controller 5. At the same time, the test equipment 4 is controlled to test the smart cockpit controller 5. Specifically, the test slave 3 controls the programmable power supply to generate a voltage offset. Under this condition, the test slave 3 performs various test operations on the smart cockpit controller 5 through the ADB debugging bridge, such as installing, uninstalling, starting applications, viewing system information, file transfer, and performance monitoring. The test slave 3 passes these tests to detect whether the functionality of the software of the smart cockpit controller 5 is complete. The test slave 3 simulates the automobile bus system through the bus test tool (CANOE) to detect the input and output interfaces of the intelligent cockpit controller 5. The bus test tool (CANOE) sends an excitation signal to the intelligent cockpit controller 5 according to the automated test script in the test slave 3. The bus test tool (CANOE) determines whether the test passes based on the response.

[0044] The intelligent cockpit controller 5 outputs the test results to the test slave 3, and the test slave 3 organizes the test data through the allure test report tool to generate a test report.

[0045] The present invention distributes automatic test tasks to the test slave 3 through the JENKINS automation server 2. The test slave 3 and the test equipment 4 controlled by the tested slave 3 cooperate with each other to automatically complete the test of the intelligent cockpit controller 5 and output the test results, thereby improving the automation and efficiency of the test.

[0046] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
