aperçu
Portable tool for LLVM- and Clang-style test suites
historique
lit, the LLVM Integrated Tester, is the portable test runner used for LLVM- and Clang-style test suites. It discovers tests, runs them in parallel, summarizes pass and failure results, and drives the small regression tests that are central to LLVM development.
lit developed inside the LLVM project as the project's Python-based test runner. The LLVM documentation describes it as lightweight, portable, and intentionally simple at the command line, while still flexible enough to support different test formats and suite layouts.
As LLVM grew into a family of compiler infrastructure projects, lit became part of the shared contributor workflow. The LLVM Testing Infrastructure Guide documents regression tests under `llvm/test`, `llvm-lit` invocations for individual files and directories, `check-*` build targets, and the use of lit configuration files such as `lit.cfg` and `lit.site.cfg.py`.
lit's adoption is unusually deep for a small Python test tool because it is carried by LLVM, Clang, LLD, MLIR, and downstream compiler projects. The PyPI package made the runner available outside a full LLVM checkout, while distribution packages such as Homebrew's `lit` make it convenient for projects that want LLVM-style tests without building all of LLVM.
The common pattern is to put `RUN:` lines in test files, use FileCheck or project tools to validate output, and run suites through `lit`, `llvm-lit`, or build-system targets like `check-llvm` and `check-all`. lit's configuration files let projects define substitutions, features, test suffixes, environment settings, and custom formats.
lit matters to package maintainers because it is a tiny command whose real importance comes from compiler ecosystems. Packaging it separately lets downstream projects run conformance and regression tests without hauling in an entire LLVM build tree.
