The vehicle-mounted camera test system may further include an execution unit, in which a processing unit (ICameraCaseHander) may be included. For example, a test service logic (BaseTask) of the vehicle-mounted camera may be preset in the processing unit. Because the test service logic and the test cases of the vehicle-mounted camera and the corresponding execution logic of the test cases are stored in different positions, in the process of testing the vehicle-mounted camera, the required test cases can be selected from the test case management unit according to requirements, the control logic separation of the service logic and the cases is realized, and the decoupling effect is achieved.

Meanwhile, the vehicle-mounted camera is controlled through the independent control unit, if the calling service logic needs to be modified in the process of calling the vehicle-mounted camera, the calling logic of the vehicle-mounted camera only needs to be modified in the control unit, and each test case does not need to be modified, so that codes can be simplified, and code redundancy is avoided.
The execution unit may further include a display unit (ICameraCaseView), and the display unit may display an image captured by the vehicle-mounted camera, and may also display an image processed according to each test case in the test process, which is not limited specifically herein. According to the embodiment of the application, the camera picture real-time preview effect is added for each use case, the problem discovery is advanced, therefore, whether the test is failed due to external reasons or camera problems can be conveniently judged, and the communication cost caused by non-technical reasons is reduced.

According to the embodiment of the application, the problem discovery is preposed by adding the real-time preview effect of the camera picture for each use case, so that the test failure caused by external reasons or camera problems can be conveniently judged, and the communication cost caused by non-technical reasons is reduced.
