Scenario: Building a large-scale Playwright E2E suite where hundreds of tests run concurrently, each needing a unique, isolated, and complex backend state (e.g., specific user orders, inventory levels). How do you architect for true isolation, rapid state provisioning, and robust cleanup?
Running concurrent, stateful E2E tests presents significant challenges for reliable CI/CD feedback. Cross-test contamination due to shared backend resources leads to flaky, hard-to-debug failures.
• Isolation Strategy: Ephemeral Environments per Worker
Leverage dynamic, containerized environments for true isolation.
• Docker Compose or Testcontainers can spin up a fresh, dedicated microservice stack (including databases) for each Playwright worker process or even per test file.
