2 lit - A Software Testing Tool
3 ===============================
5 lit is a portable tool for executing LLVM and Clang style test suites,
6 summarizing their results, and providing indication of failures. lit is designed
7 to be a lightweight testing tool with as simple a user interface as possible.
13 Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
16 Before submitting patches, run the test suite to ensure nothing has regressed:
18 # From within your LLVM source directory.
20 --path /path/to/your/llvm/build/bin \
23 Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities.
24 You will need to have built LLVM tools in order to run lit's test suite
27 You'll also want to confirm that lit continues to work when testing LLVM.
28 Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the
29 regression test suite:
33 And be sure to run the llvm-lit wrapper script as well:
35 /path/to/your/llvm/build/bin/llvm-lit utils/lit/tests
37 Finally, make sure lit works when installed via setuptools:
39 python utils/lit/setup.py install
40 lit --path /path/to/your/llvm/build/bin utils/lit/tests
