Running tests in Clang

Clang Frontend
1

Hello Devs,

I would like to understand how clang test system works. Specially the tests in $project_dir/llvm/tools/clang/test and also how I can use TestRunner.sh to run a single test.

Appreciate if someone could point me to a relevant documentation or give a brief introduction on how it works.

Thank you
Regards

Hello Devs,

TestRunner.sh to run a single test.

If you're using the CMake build system, then the targets `check-all` and `check-clang` will run the whole clang testsuite for you.

If you want to run a single testcase, then use llvm-lit from the bin directory of the build, and pass it the path to the testcase or directory of testcases.
