e2e-testing-patterns SKILL.md skillA
e2e-testing-patterns from wshobson/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wshobson/agents/e2e-testing-patterns@git:20261015.8cc4f42Pins git:20261015.8cc4f42 in mdr.lock. Pin the fingerprint instead.

Master end-to-end testing with Playwright and Cypress to build reliable test suites that catch bugs, improve confidence, and enable fast deployment. Use when implementing E2E tests, debugging flaky tests, or establishing testing standards.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# E2E Testing Patterns
Build reliable, fast, and maintainable end-to-end test suites that provide confidence to ship code quickly and catch regressions before users do.
## When to Use This Skill
- Implementing end-to-end test automation
- Debugging flaky or unreliable tests
- Testing critical user workflows
- Setting up CI/CD test pipelines
- Testing across multiple browsers
- Validating accessibility requirements
- Testing responsive designs
- Establishing E2E testing standards
## Core Concepts
### 1. E2E Testing Fundamentals
**What to Test with E2E:**
- Critical user journeys (login, checkout, signup)
- Complex interactions (drag-and-drop, multi-step forms)
- Cross-browser compatibility
- Real API integration
- Authentication flows
**What NOT to Test with E2E:**
- Unit-level logic (use unit tests)
- API contracts (use integration tests)
- Edge cases (too slow)
- Internal implementation details
### 2. Test Philosophy
**The Testing Pyramid:**
```
/\
/E2E\ ← Few, focused on critical paths
/─────\
/Integr\ ← More, test component interactions
/────────\
/Unit Tests\ ← Many, fast, isolated
/────────────\
```

How to install
mdr add wshobson/agents/e2e-testing-patterns@sha256:b59a3d80c852f41bThe line at the top of this page pins the label git:20261015.8cc4f42, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
