When running cppcheck premium with MISRA C++2023 Rule 6.5.1 enabled on unittests using googletests with --library=googletest, cppcheck is flagging each TEST(test_suite_name, test_name) with violation of Rule 6.5.1.

Encapsulating the definition in an anonymous namespace ensures MIRSA compliance.

Thanks for letting me know @danmar.
I'll look into it, I guess I need to familiarize myself with the tests first.

After thinking about the modification, I no longer think that my changes make sense at all, sorry.
It would only include the function signature in the namespace but not the function body, which is what I intended.

With this insight, I withdraw this PR, to make room for a better approach
