 - [ ] I have added tests relevant to the introduced functionality, and the unit tests are passing locally
+- [ ] I have added the test to REGRESSION_TESTS list defined at the top of CMakeLists.txt in tests/CMakeLists.txt, **IF** the test takes more than 30 seconds to run.
 - [ ] I have added inline documentation which enables the maintainers with understanding the motivation
 - [ ] I have removed the stale documentation which is no longer relevant after this pull request
 - [ ] (If this change is user-facing) I have added release notes which provide the end users with a brief summary of the improvement from this pull request
