Sharding splits your test suite across multiple parallel workers, dramatically reducing total run time.
## The Strategy
Use `--shard=1/4`, `--shard=2/4`, etc. across separate GitHub Actions jobs.
## The Workflow
```yaml
strategy:
matrix:
shard: [1, 2, 3, 4]
steps:
- run: npx playwright test --shard=${{ matrix.shard }}/4
```
