`test_macros.h` is created to provide various macros acting as aliases for
doctest macros to work better with Godot internals and conventions. This also
makes it accessible for those who'd like to start writing tests in Godot, as
most vital information can be put together and documented directly in
`test_macros.h` header.
Developers are encouraged to include the new `tests/test_macros.h` for writing
new tests over `thirdparty/doctest/doctest.h`.
Added `TEST_CASE_PENDING("name")` as an alias for
`TEST_CASE("name", doctest::skip())` which could be used to mark failing tests
for issues yet to be fixed, so as to not affect CI testing results.
Added `ERR_PRINT_OFF` and `ERR_PRINT_ON` to control error printing for testing
various **expected** failure paths within Godot without polluting the test
summary with error messages.
Modules-specific tests can be written under respective module folders.
Each module should have "tests" folder created with the tests implemented
as `doctest` headers, so they can be collected by the buildsystem and
included directly in `tests/test_main.cpp` to be compiled.
