E2E Testing (User Flows)

Overview

End-to-end tests should protect a small set of critical user journeys that only fail when the real stack is exercised together. Prefer a lean, reliable suite that verifies high-risk flows over a sprawling browser script collection that duplicates lower-level tests and flakes constantly.

Follow This Workflow

1. Choose the right user flows

• Prioritize sign-in, checkout, onboarding, core CRUD journeys, privileged actions, and other revenue- or trust-critical paths.
• Focus on cross-stack regressions that unit and integration tests cannot catch.
• Keep the suite small enough that failures remain actionable.

2. Design the scenario boundary
