Speed up E2E tests by caching data between workers
When running E2E tests in parallel, you might need to:
✅ Authenticate user only once
✅ Seed database only once
✅ Compute heavy values on demand
✅ Reuse heavy-computed values across workers
✅ Persist heavy-computed values between test runs
Global Cache makes all of this possible.
The first worker to request a key computes its value. Concurrent workers wait for that computation and then receive the same cached result.
