Test coordinate parallel test execution across multiple environments and frameworks. Use when performing specialized testing. Trigger with phrases like "orchestrate tests", "run parallel tests", or "coordinate test execution".

Coordinate parallel test execution across multiple test suites, frameworks, and environments. Manages test splitting, worker allocation, result aggregation, and intelligent retry strategies.
jest --shard=i/N or pytest -n auto.--shard=i/N or Cypress parallelization.@flaky or equivalent marker..github/workflows/test.yml, .gitlab-ci.yml, or equivalent)| Error | Cause | Solution |
|---|---|---|
| Shard produces zero tests | Uneven test distribution or incorrect shard index | Verify shard count matches actual test file count; use file-based splitting |
| Worker out of memory | Too many parallel processes on one runner | Reduce --maxWorkers or -n count; increase runner memory; use --workerIdleMemoryLimit |
| Test ordering dependency | Tests pass in isolation but fail in specific shard order | Add --randomize flag; fix shared state leaks; enforce test independence |
| Result aggregation mismatch | Missing shard results due to job timeout | Set job-level timeouts higher than test timeouts; add result upload as a separate step |
| CI cache miss slowing startup | Dependencies not cached between parallel jobs | Configure dependency caching per lockfile hash; use a shared setup job |
