Please describe your feature request and the solution you'd like.

Currently, the unit test cases and integration test cases of platform base are not complete enough. Testing code is a very useful means to improve software quality, helping us find software bugs in advance, re-examine the written code and optimize it.

It would be better if unit test cases and integration test cases could be supplemented.

When writing test code, it should not only include simple interface calls to normal functions, but also conduct as much coverage unit testing and integration testing of main logic as possible based on various logical branches in the code. At the same time, it should also include the construction of abnormal scenario test cases.

PR for this feature from new contributor are welcome.
