How to run particular clang-test test?

Hi there! May be a stupid question, but how to run a particular test for clang? Is here some way?
Thanks!

Answered to myself. Looks like '-verify' parameter replaced direct 'lit' invokation. So in order to run particular test you should type:
<path to llvm build>/bin/clang <parameters you need> -verify -internal-isystem /Users/stepan/projects/shared/toolchains/llvm.git.darwin-debug-x86_64/lib/clang/9.0.0/include -nostdsysteminc -<your test file>

Hi,
You could run

$ /path/to/llvm-lit /path/to/single-test.test

to run a single test.
