A Software Testing Tool

Project description

About

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.

Features

  • Portable!

  • Flexible test discovery.

  • Parallel test execution.

  • Support for multiple test formats and test suite designs.

Documentation

The official lit documentation is in the man page, available online at the LLVM Command Guide: http://llvm.org/cmds/lit.html.

Source

The lit source is available as part of LLVM, in the LLVM source repository: https://github.com/llvm/llvm-project/tree/main/llvm/utils/lit

Contributing to lit

Please browse the issues labeled tools:llvm-lit in LLVM’s issue tracker for ideas on what to work on: https://github.com/llvm/llvm-project/labels/tools%3Allvm-lit

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 \
    utils/lit/tests

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 successfully.

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
