nextest-runner 0.105.0

nextest-runner-0.105.0

[nextest-runner] version 0.105.0

nextest-metadata 0.13.3

Added

• MismatchReason::ALL_VARIANTS iterates over all known variants of MismatchReason.

cargo-nextest 0.9.124

Fixed

The unsupported install mechanism, cargo install cargo-nextest without --locked, now fails with a helpful error message asking you to use cargo install --locked cargo-nextest.

Note that this unsupported method was broken with version 0.9.123 due to a dependency update, resulting in several issues being filed. We hope that the new mechanism results in clearer, more helpful guidance.

nextest-runner-0.104.0

[nextest-runner] version 0.104.0

cargo-nextest 0.9.123

This is a major release with several new features. If you run into issues, please file a bug.

Added

• Major new feature: experimental support for recording, replaying, and rerunning test runs. Enable by adding record = true to the [experimental] section in user config, or by setting NEXTEST_EXPERIMENTAL_RECORD=1.

  Once enabled, recording can be turned on by adding enabled = true to the [record] section in user config. Recorded runs are stored in the system cache directory.

  New commands:

  • cargo nextest replay: Replay a test run (by default, the latest completed run).
  • cargo nextest run -R latest: Rerun tests that failed the last time.
  • cargo nextest store list: List all recorded runs.
  • cargo nextest store info: Show details about a specific run.
  • cargo nextest store prune: Prune old recorded runs.

• A new --user-config-file option (environment variable NEXTEST_USER_CONFIG_FILE) allows explicit control over user configuration loading. Pass a path to a specific config file, or none to skip user config entirely.

• A new --cargo-message-format option enables live streaming of Cargo's JSON messages to standard out. This feature is equivalent to cargo test --message-format.

Changed

• The experimental section in repository config can now also be a table, not just an array. The previous array syntax is deprecated but still supported. For example:

  # New style (recommended).
  [experimental]
  benchmarks = true
  
  # Old style (deprecated)
  experimental = ["benchmarks"]

  Note that user configuration's experimental is always a table. The array syntax is not supported in that case.

  This change enables upcoming config set support over the command line.

• When a config file specifies both a future nextest-version and an unknown experimental feature, the version error now takes precedence. This produces clearer error messages for users running older nextest versions.

Fixed

• Fixed another panic with on-timeout = "pass" in a different code path than the 0.9.117 fix. Thanks gakonst for your first contribution! (#2940)
