# Core Cross Platform Regression Tests

CI Unit test cases that will run on all platforms.
To reduce the CI burden, we only put in test-cases that are platform sensitive.
Please use the following guideline:

- Always consider add tests to the unittest folder first.
- If a problems that passes the Linux pipeline but fails in Windows or MacOS,
  we should isolate the problem, write a minimal regression test case
  and add it to this folder.
- A test case in this folder should be minimal and finish in a reasonable amount of time.
- Document about why it should be in the all-platform-minimal-test.
