Thomas Preud'homme d618c6e8ce [lit, test] Fix test cancellation feature detection A lit feature guards tests for the lit timeout functionality because on most system it depends on the availability of the psutil Python module. However, that feature is defined based on the ability of the testing lit to cancel test, which does not necessarily apply to the ability of the tested lit. In particular, RUN commands have a cleared PYTHONPATH and user site packages are disabled. In the case where psutil is found by the testing lit from one of those two source of python path, the tested lit would not be able to find it, causing timeout tests to fail. This commit fixes the issue by testing the ability to cancel tests in the RUN command environment. Reviewed By: yln Differential Revision: https://reviews.llvm.org/D99728		2021-04-20 12:09:30 +01:00

===============================
 lit - A Software Testing Tool
===============================

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.

=====================
 Contributing to lit
=====================

Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
what to work on.

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
