# which is always placed before `${clang-tools}/bin` in PATH. `clang-tidy` provided in
# `clang-unwrapped` cause tests failing because it is not wrapped to resolve header search paths.

# As a temporary fix, we disabled these tests when using clang stdenv
# cannot use lib.optionalString as it creates an empty string, disabling all tests
