1=============================== 2 lit - A Software Testing Tool 3=============================== 4 5lit is a portable tool for executing LLVM and Clang style test suites, 6summarizing their results, and providing indication of failures. lit is designed 7to be a lightweight testing tool with as simple a user interface as possible. 8 9===================== 10 Contributing to lit 11===================== 12 13Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on 14what to work on. 15 16Before submitting patches, run the test suite to ensure nothing has regressed: 17 18 # From within your LLVM source directory. 19 utils/lit/lit.py \ 20 --path /path/to/your/llvm/build/bin \ 21 utils/lit/tests 22 23Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities. 24You will need to have built LLVM tools in order to run lit's test suite 25successfully. 26 27You'll also want to confirm that lit continues to work when testing LLVM. 28Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the 29regression test suite: 30 31 make check-llvm 32 33And be sure to run the llvm-lit wrapper script as well: 34 35 /path/to/your/llvm/build/bin/llvm-lit utils/lit/tests 36 37Finally, make sure lit works when installed via setuptools: 38 39 python utils/lit/setup.py install 40 lit --path /path/to/your/llvm/build/bin utils/lit/tests 41 42
