| lit - A Software Testing Tool
|lit is a portable tool for executing LLVM and Clang style test suites,
|summarizing their results, and providing indication of failures. lit is designed
|to be a lightweight testing tool with as simple a user interface as possible.

|Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
|what to work on.
|Before submitting patches, run the test suite to ensure nothing has regressed:
| # From within your LLVM source directory.
| utils/lit/lit.py \
| --path /path/to/your/llvm/build/bin \
|Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities.
|You will need to have built LLVM tools in order to run lit's test suite
|You'll also want to confirm that lit continues to work when testing LLVM.
|Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the
|regression test suite:
| make check-llvm
|And be sure to run the llvm-lit wrapper script as well:
| /path/to/your/llvm/build/bin/llvm-lit utils/lit/tests
|Finally, make sure lit works when installed via setuptools:
| python utils/lit/setup.py install
| lit --path /path/to/your/llvm/build/bin utils/lit/tests
