pytest-cmake-presets was written to find and "test" cmake-presets(7) as
part of the IXM test harness. Each test is a single CMake preset that
might be part of a larger project. There are two aspects to tests: running
presets directly, and then testing the layout/result of the
cmake-file-api(7) after the fact. These second tests are performed via
normal pytest functions.
Tests can use the vendor.pytest-cmake-presets field to modify the expected
outcome of some tests.
Specifically, fields like pass-regex, will-fail, etc., can all modify the
behavior of an executed CMakePresetItem, allowing for some behavior to be
modified in a data-oriented fashion, instead of requiring pytest fixtures to
execute.
