Green unit tests don't guarantee production readiness
Auth0's parent company Auth0 (now part of Okta) describes a single end-to-end Playwright test that simulates a full tenant lifecycle, from signup to deletion, exercising all features like SSO, SCIM, MFA, and custom claims. The test uses freshly minted credentials and a real consumer app to verify that combinations of features work together, not just isolated units. A failure in any step blocks shipping, ensuring that the integration works in practice, not just in theory.

This pragmatic approach highlights a common gap in CI/CD pipelines: unit tests alone can't catch integration bugs, especially in complex auth systems where feature interactions are critical.
