Running tests manually is slow and error-prone, and coverage results can become misleading when stale artifacts from previous runs are combined with current results.
.coverage shards are removed before combining worker results.Use the command bash .claude/skills/run-tests/scripts/test.sh -p to run the pytest suite in parallel with verbose output.

Run pytest in parallel by using the test harness script with the parallelism flag, which leverages pytest-xdist to distribute tests across CPU cores for faster feedback. This provides rapid validation after refactors or hotfixes.
Misleading pytest code coverage results often occur when stale `.coverage` shards from previous runs are combined with current results. The test harness removes stale artifacts before combining worker outputs to ensure accurate reporting.
Validate tests with a CI-like quality gate by running the test harness in CI mode, which enables parallel execution, coverage reporting, and optional XML output to detect issues that only appear under CI conditions before merging.
Yes, you can run a specific failing pytest file without parallelism to diagnose flaky tests. The test harness supports targeted debugging by allowing execution of individual test files without distributing them across CPU cores.
pytest-xdist is required for parallel test execution with this bash test runner. The script uses it to distribute tests across CPU cores and combines the resulting coverage shards from each worker for the final report.
The best way to combine coverage data from parallel pytest workers is to clear stale `.coverage` shards before execution and let the test harness safely merge the worker results, failing safely if reports cannot be produced.
