cargo-nextest 0.9.27

on GitHub

This is a major architectural rework of nextest. We've tested it thoroughly to the best of our ability, but if you see regressions please report them!

If you encounter a regression, you can temporarily pin nextest to the previous version in CI. If you're on GitHub Actions and are using taiki-e/install-action, use this instead:

- uses: taiki-e/install-action@v1
- with:
    tool: nextest
    version: 0.9.26

Added

• Nextest now works with the Miri interpreter. Use cargo miri nextest run to run your tests with Miri.
• Nextest now detects some situations where tests leak subprocesses. Previously, these situations would cause nextest to hang.
• Per-test overrides now support slow-timeout and the new leak-timeout config parameter.
• A new option --tool-config-file allows tools that wrap nextest to specify custom config settings, while still prioritizing repository-specific configuration.

Changed

• Major internal change: The nextest list and run steps now use Tokio. This change enables the leak detection described above.
• The list step now runs list commands in parallel. This should result in speedups in most cases.

Fixed

• Nextest now redirects standard input during test runs to /dev/null (or NUL on Windows). Most tests do not read from standard input, but if a test does, it will no longer cause nextest to hang.
• On Windows, nextest configures standard input, standard output and standard error to not be inherited. This prevents some kinds of test hangs on Windows.
• If a dynamic library link path doesn't exist, nextest no longer adds it to LD_LIBRARY_PATH or equivalent. This should have no practical effect.
• Archiving tests now works even if the target directory is not called "target".
