This invention discloses a vehicle infotainment system testing method. By having a controller uniformly receive modal simulation parameters, generate precise multimodal interaction commands, and coordinate the synchronous actions of the multimodal interaction simulation device and the audio / video acquisition device, a fully automated closed-loop testing process is constructed. This application fundamentally eliminates the randomness and uncertainty caused by manual operation. Since the test input commands (such as voice content, touch coordinates, and timing) are precisely reproduced by the device according to preset parameters, and the entire execution, acquisition, and judgment process is automatically driven by the controller, it ensures that the test conditions, execution steps, and triggering logic remain consistent at any time and for any number of tests. This application's embodiments make performance test results (such as response latency) objectively comparable, providing a reliable and consistent technical foundation for accurately evaluating vehicle infotainment system performance and identifying performance regression between versions.

This invention provides a database testing method, apparatus, electronic device, and storage medium based on protocol layer interaction. It generates test SQL statements, performs parameterization to form parameter placeholder structures, and extracts parameter constraint information. Based on the parameter placeholder structures, parameter constraint information, and the current session state, it generates protocol test cases, sequentially sends multiple protocol data packets, receives and parses response data packets returned by the database system, records communication error information during response reading, and updates the current session state based on the parsing results of the response data packets. When the communication error information is detected during response reading, if a crash occurs or the verification results are inconsistent, an error report is generated. This invention can cover protocol processing paths under different execution stages and interaction sequences, reduce invalid requests with semantically invalid or easily rejected requests, improve the validity of test input, and enhance the coverage depth and defect detection capability of database protocol testing.
