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.

Brian Gesiakba7c3272016-11-03 23:41:49 +000013Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
14what to work on.

Daniel Dunbar97c9e022016-09-27 18:58:50 +000016Before 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
Brian Gesiak46ea0612016-10-22 17:27:31 +000027You'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
