If not, the platform automatically generates a test report for this task based on the test results.

[0018] In an optional embodiment, the strategy that needs to be upgraded is configured in step S1. The specific strategy includes which ECU to upgrade, from which version to which version, upgrade precondition configuration, failure retry and rollback, etc., and then the upgrade task is created and automatically released, so that the version can be detected when the vehicle performs OTA detection.

[0019] In an optional embodiment, in step S2, a detection step is added (click the button on the XPATH recognition interface to click), a download step is added (download the button on the XPATH recognition interface to download), an installation step is added (install the button on the XPATH recognition interface to install), and the cloud CASE is associated (before the vehicle-side version is detected, the cloud can track the cloud-based automated CASE and automatically release the upgrade task).

Click and other operations are performed, and detection and download are automatically performed according to the steps. After the execution is completed, the expected results of the case configuration are compared with the actual results, and the installation results are reported to the OTA automated test cloud platform.

[0021] An automated test system based on automobile OTA whole vehicle upgrade consists of four parts: OTA automated test cloud platform, OTA automated test terminal, external equipment and tested system.

[0022] In an optional embodiment, the OTA automated testing platform provides test case maintenance, test script editing, and automated test task delivery functions (see Appendix Figure 4 ).

[0023] In an optional embodiment, the function of the OTA automated test terminal is device-side control (ECU device based on the Android system), and the technical architecture adopts Python3.8+UiAutomator2 to realize the automated control of the Andorid device side. The overall process is: the test terminal receives the automated test task issued by the automated cloud platform, parses the task, executes the automated script issued in the task, and reports the execution result to the automated cloud platform.

[0024] In an optional embodiment, the function of the external device is that the automated test terminal controls some functions of the system under test through the external device, such as an external relay to automatically control the power on and off of the ECU, an external programmable power supply to automatically control the power on and off of the control rack equipment, and an external CAN card to automatically control the sending and receiving of messages.

[0025] In an optional embodiment, the system under test may be a test bench, a whole vehicle or a mobile phone APP.

[0026] The present invention: Automated testing, one-click report generation The characteristics of OTA automated testing are reflected in the fact that testers can flexibly select a set of test cases and submit them to the test system. The test system can automatically execute the corresponding test scripts according to the test cases submitted by the testers, and finally output a test report, which includes the test prerequisites, detailed test steps and expected results of each step. If a test fails, the possible reasons for the failure can be given based on the test steps and the information returned by the step to help relevant personnel locate the problem.

[0027] Flexible switching between system testing and single-unit testing to meet functional verification requirements at different development stages OTA remote upgrades cover the stages from vehicle design, R&D, production to user use, and the OTA automated test cycle has also been expanded. The OTA test content at different stages varies greatly, and may involve single-unit testing, system testing, software package stress testing, etc. By changing the test system configuration conditions and adapting some software modules, OTA testing can be connected at different stages.

[0028] Vehicle-side automated test cases can be associated with OTA cloud cases Utilize the OTA automated testing cloud platform to conduct OTA vehicle-side automated testing. The upgrade strategies and upgrade tasks that were originally required to be configured in the cloud during manual testing can now be created as cloud-based automated cases in the bug-free testing platform and associated with the vehicle-side automated testing cases, allowing the entire OTA process to be fully automated (platform automated release tasks -> vehicle-side automated OTA upgrades).

[0029] Modular software architecture, easy to expand use cases Usually, different models have different OTA strategies under the same OTA functional architecture. In order to adapt to different models, the software architecture of the test system adopts a modular design concept to adapt to changes in network node message interaction processes and expansion of test cases. The software system is divided into several small modules according to the level and functional logic. Each module implements independent functions. The changes in OTA strategies and expansion of test cases can be handled by combining different modules and modifying parameters.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
