AI Technical Summary

Technical Problem

In existing technologies, the message filtering function of CAN controllers is inefficient to test, making it difficult to cover all transmitted message ID values ​​and ACC_ID/ACC_ID_MASK configuration values. Furthermore, the recording of test results is time-consuming and error-prone, and test metrics cannot be quantified.

Method used

The host computer automatically configures the registers of the target controller, determines the target ID range based on the current register information, and automatically tests the message filtering function by actually receiving messages and test information, thereby achieving automated testing and reducing the delay and error of manual operation.

Benefits of technology

It improves testing efficiency and accuracy, reduces testing time overhead, ensures the accuracy and consistency of configuration, and provides quantitative performance evaluation and fault identification capabilities.

Abstract

The embodiment of the invention provides a test method which can be executed by an upper computer and is used for testing a message filtering function of a target controller in a tested device. When the method is implemented, after a target test case is executed, current register information of a target controller is automatically obtained, and a target ID range is determined according to the current register information. And then, based on test information such as an actual received message and a target ID range, automatically completing a filtering function test. According to the method, the controller can be automatically configured through the register configuration information in the test case, the register state is automatically obtained after testing, and full-process automation is achieved. Errors, delay and interruption possibly caused by manual configuration, record reading and result checking are avoided, and the continuity, efficiency and accuracy of the testing process are remarkably improved.
