+# E2E Testing Patterns
+
+Build reliable, fast end-to-end test suites with Playwright and Cypress. Critical user journey coverage, flaky test elimination, and CI/CD integration.
+
+## What's Inside
+
+- Test pyramid guidance (what E2E tests are for vs. not for)
+- Core principles (behavior over implementation, independent tests, deterministic waits, stable selectors)
+- Playwright patterns (config, Page Object Model, fixtures, smart waiting, network mocking)
+- Cypress patterns (custom commands, network intercepts)
+- Selector strategy with priority ranking (roles → labels → data-testid → text)
+- Visual regression testing
+- Accessibility testing with axe-core
+- Debugging failed tests (headed mode, trace viewer, test steps)
+- Flaky test diagnosis checklist
+- CI/CD integration with GitHub Actions
+
+## When to Use
+
+- Implementing E2E test automation for a web application
+- Debugging flaky tests that fail intermittently
+- Setting up CI/CD test pipelines with browser tests
+- Testing critical user workflows (auth, checkout, signup)
+- Choosing what to test with E2E vs unit/integration tests

+# E2E Testing Patterns
+
+> Test what users do, not how code works. E2E tests prove the system works as a whole — they're your confidence to ship.

+
+## WHAT This Skill Does
+
+Provides patterns for building end-to-end test suites that:
+- Catch regressions before users do
+- Run fast enough for CI/CD
+- Remain stable (no flaky failures)
+- Cover critical user journeys without over-testing
+
+## WHEN To Use
+
+- **Implementing E2E test automation** for a web application
+- **Debugging flaky tests** that fail intermittently
+- **Setting up CI/CD test pipelines** with browser tests
+- **Testing critical user workflows** (auth, checkout, signup)
+- **Choosing what to test with E2E** vs unit/integration tests
+
+---
+
+## Test Pyramid — Know Your Layer
+
+```
+        /\
+       /E2E\         ← FEW: Critical paths only (this skill)
+      /─────\
+     /Integr\        ← MORE: Component interactions, API contracts
+    /────────\
+   /Unit Tests\      ← MANY: Fast, isolated, cover edge cases
+  /────────────\
+```
+
+### What E2E Tests Are For
+
+| E2E Tests ✓ | NOT E2E Tests ✗ |
+|-------------|-----------------|
+| Critical user journeys (login → dashboard → action → logout) | Unit-level logic (use unit tests) |
+| Multi-step flows (checkout, onboarding wizard) | API contracts (use integration tests) |
+| Cross-browser compatibility | Edge cases (too slow, use unit tests) |
+| Real API integration | Internal implementation details |
+| Authentication flows | Component visual states (use Storybook) |
+
+**Rule of thumb:** If it would devastate your business to break, E2E test it. If it's just inconvenient, test it faster with unit/integration tests.
+
+---
+
+## Core Principles
+
+| Principle | Why | How |
+|-----------|-----|-----|
+| **Test behavior, not implementation** | Survives refactors | Assert on user-visible outcomes, not DOM structure |
+| **Independent tests** | Parallelizable, debuggable | Each test creates its own data, cleans up after |
+| **Deterministic waits** | No flakiness | Wait for conditions, not fixed timeouts |
+| **Stable selectors** | Survives UI changes | Use `data-testid`, roles, labels — never CSS classes |
+| **Fast feedback** | Developers run them | Mock external services, parallelize, shard |
+
+---
+
+## Playwright Patterns
+
+### Configuration
+
+```typescript
+// playwright.config.ts
+import { defineConfig, devices } from "@playwright/test";
+
+export default defineConfig({
+  testDir: "./e2e",
+  timeout: 30000,
+  expect: { timeout: 5000 },
+  fullyParallel: true,
+  forbidOnly: !!process.env.CI,
+  retries: process.env.CI ? 2 : 0,
+  workers: process.env.CI ? 1 : undefined,
+  reporter: [["html"], ["junit", { outputFile: "results.xml" }]],
+  use: {
+    baseURL: "http://localhost:3000",
+    trace: "on-first-retry",
+    screenshot: "only-on-failure",
+    video: "retain-on-failure",
+  },
+  projects: [
+    { name: "chromium", use: { ...devices["Desktop Chrome"] } },
+    { name: "firefox", use: { ...devices["Desktop Firefox"] } },
+    { name: "webkit", use: { ...devices["Desktop Safari"] } },
+    { name: "mobile", use: { ...devices["iPhone 13"] } },
+  ],
+});
+```
+
+### Pattern: Page Object Model
+
+Encapsulate page logic. Tests read like user stories.
+
+```typescript
+// pages/LoginPage.ts
+import { Page, Locator } from "@playwright/test";
+
+export class LoginPage {
+  readonly page: Page;
+  readonly emailInput: Locator;
+  readonly passwordInput: Locator;
+  readonly loginButton: Locator;
+  readonly errorMessage: Locator;
+
+  constructor(page: Page) {
+    this.page = page;
+    this.emailInput = page.getByLabel("Email");
+    this.passwordInput = page.getByLabel("Password");
+    this.loginButton = page.getByRole("button", { name: "Login" });
+    this.errorMessage = page.getByRole("alert");
+  }
+
+  async goto() {
+    await this.page.goto("/login");
+  }
+
+  async login(email: string, password: string) {
+    await this.emailInput.fill(email);
+    await this.passwordInput.fill(password);
+    await this.loginButton.click();
+  }
+}
+
+// tests/login.spec.ts
+import { test, expect } from "@playwright/test";
+import { LoginPage } from "../pages/LoginPage";
+
+test("successful login redirects to dashboard", async ({ page }) => {
+  const loginPage = new LoginPage(page);
+  await loginPage.goto();
+  await loginPage.login("user@example.com", "password123");
+
+  await expect(page).toHaveURL("/dashboard");
+  await expect(page.getByRole("heading", { name: "Dashboard" })).toBeVisible();
+});
+```
+
+### Pattern: Fixtures for Test Data
+
+Create and clean up test data automatically.
+
+```typescript
+// fixtures/test-data.ts
+import { test as base } from "@playwright/test";
+
+export const test = base.extend<{ testUser: TestUser }>({
+  testUser: async ({}, use) => {
+    // Setup: Create user
+    const user = await createTestUser({
+      email: `test-${Date.now()}@example.com`,
+      password: "Test123!@#",
+    });
+
+    await use(user);
+
+    // Teardown: Clean up
+    await deleteTestUser(user.id);
+  },
+});
+
+// Usage — testUser is created before, deleted after
+test("user can update profile", async ({ page, testUser }) => {
+  await page.goto("/login");
+  await page.getByLabel("Email").fill(testUser.email);
+  // ...
+});
+```
+
+### Pattern: Smart Waiting
+
+Never use fixed timeouts. Wait for specific conditions.
+
+```typescript
+// ❌ FLAKY: Fixed timeout
+await page.waitForTimeout(3000);
+
+// ✅ STABLE: Wait for conditions
+await page.waitForLoadState("networkidle");
+await page.waitForURL("/dashboard");
+
+// ✅ BEST: Auto-waiting assertions
+await expect(page.getByText("Welcome")).toBeVisible();
+await expect(page.getByRole("button", { name: "Submit" })).toBeEnabled();
+
+// Wait for API response
+const responsePromise = page.waitForResponse(
+  (r) => r.url().includes("/api/users") && r.status() === 200
+);
+await page.getByRole("button", { name: "Load" }).click();
+await responsePromise;
+```
+
+### Pattern: Network Mocking
+
+Isolate tests from real external services.
+
+```typescript
+test("shows error when API fails", async ({ page }) => {
+  // Mock the API response
+  await page.route("**/api/users", (route) => {
+    route.fulfill({
+      status: 500,
+      body: JSON.stringify({ error: "Server Error" }),
+    });
+  });
+
+  await page.goto("/users");
+  await expect(page.getByText("Failed to load users")).toBeVisible();
+});
+
+test("handles slow network gracefully", async ({ page }) => {
+  await page.route("**/api/data", async (route) => {
+    await new Promise((r) => setTimeout(r, 3000)); // Simulate delay
+    await route.continue();
+  });
+
+  await page.goto("/dashboard");
+  await expect(page.getByText("Loading...")).toBeVisible();
+});
+```
+
+---
+
+## Cypress Patterns
+
+### Custom Commands
+
+```typescript
+// cypress/support/commands.ts
+declare global {
+  namespace Cypress {
+    interface Chainable {
+      login(email: string, password: string): Chainable<void>;
+      dataCy(value: string): Chainable<JQuery<HTMLElement>>;
+    }
+  }
+}
+
+Cypress.Commands.add("login", (email, password) => {
+  cy.visit("/login");
+  cy.get('[data-testid="email"]').type(email);
+  cy.get('[data-testid="password"]').type(password);
+  cy.get('[data-testid="login-button"]').click();
+  cy.url().should("include", "/dashboard");
+});
+
+Cypress.Commands.add("dataCy", (value) => {
+  return cy.get(`[data-cy="${value}"]`);
+});
+
+// Usage
+cy.login("user@example.com", "password");
+cy.dataCy("submit-button").click();
+```
+
+### Network Intercepts
+
+```typescript
+// Mock API
+cy.intercept("GET", "/api/users", {
+  statusCode: 200,
+  body: [{ id: 1, name: "John" }],
+}).as("getUsers");
+
+cy.visit("/users");
+cy.wait("@getUsers");
+cy.get('[data-testid="user-list"]').children().should("have.length", 1);
+```
+
+---
+
+## Selector Strategy
+
+| Priority | Selector Type | Example | Why |
+|----------|--------------|---------|-----|
+| 1 | **Role + name** | `getByRole("button", { name: "Submit" })` | Accessible, user-facing |
+| 2 | **Label** | `getByLabel("Email address")` | Accessible, semantic |
+| 3 | **data-testid** | `getByTestId("checkout-form")` | Stable, explicit for testing |
+| 4 | **Text content** | `getByText("Welcome back")` | User-facing |
+| ❌ | CSS classes | `.btn-primary` | Breaks on styling changes |
+| ❌ | DOM structure | `div > form > input:nth-child(2)` | Breaks on any restructure |
+
+```typescript
+// ❌ BAD: Brittle selectors
+cy.get(".btn.btn-primary.submit-button").click();
+cy.get("div > form > div:nth-child(2) > input").type("text");
+
+// ✅ GOOD: Stable selectors
+page.getByRole("button", { name: "Submit" }).click();
+page.getByLabel("Email address").fill("user@example.com");
+page.getByTestId("email-input").fill("user@example.com");
+```
+
+---
+
+## Visual Regression Testing
+
+```typescript
+// Playwright visual comparisons
+test("homepage looks correct", async ({ page }) => {
+  await page.goto("/");
+  await expect(page).toHaveScreenshot("homepage.png", {
+    fullPage: true,
+    maxDiffPixels: 100,
+  });
+});
+
+test("button states", async ({ page }) => {
+  const button = page.getByRole("button", { name: "Submit" });
+
+  await expect(button).toHaveScreenshot("button-default.png");
+
+  await button.hover();
+  await expect(button).toHaveScreenshot("button-hover.png");
+});
+```
+
+---
+
+## Accessibility Testing
+
+```typescript
+// npm install @axe-core/playwright
+import AxeBuilder from "@axe-core/playwright";
+
+test("page has no accessibility violations", async ({ page }) => {
+  await page.goto("/");
+
+  const results = await new AxeBuilder({ page })
+    .exclude("#third-party-widget")  // Exclude things you can't control
+    .analyze();
+
+  expect(results.violations).toEqual([]);
+});
+```
+
+---
+
+## Debugging Failed Tests
+
+```bash
+# Run in headed mode (see the browser)
+npx playwright test --headed
+
+# Debug mode (step through)
+npx playwright test --debug
+
+# Show trace viewer for failed tests
+npx playwright show-report
+```
+
+```typescript
+// Add test steps for better failure reports
+test("checkout flow", async ({ page }) => {
+  await test.step("Add item to cart", async () => {
+    await page.goto("/products");
+    await page.getByRole("button", { name: "Add to Cart" }).click();
+  });
+
+  await test.step("Complete checkout", async () => {
+    await page.goto("/checkout");
+    // ... if this fails, you know which step
+  });
+});
+
+// Pause for manual inspection
+await page.pause();
+```
+
+---
+
+## Flaky Test Checklist
+
+When a test fails intermittently, check:
+
+| Issue | Fix |
+|-------|-----|
+| Fixed `waitForTimeout()` calls | Replace with `waitForSelector()` or expect assertions |
+| Race conditions on page load | Wait for `networkidle` or specific elements |
+| Test data pollution | Ensure tests create/clean their own data |
+| Animation timing | Wait for animations to complete or disable them |
+| Viewport inconsistency | Set explicit viewport in config |
+| Random test order issues | Tests must be independent |
+| Third-party service flakiness | Mock external APIs |
+
+---
+
+## CI/CD Integration
+
+```yaml
+# GitHub Actions example
+name: E2E Tests
+on: [push, pull_request]
+
+jobs:
+  e2e:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v4
+      - run: npm ci
+      - run: npx playwright install --with-deps
+      - run: npm run build
+      - run: npm run start & npx wait-on http://localhost:3000
+      - run: npx playwright test
+      - uses: actions/upload-artifact@v4
+        if: failure()
+        with:
+          name: playwright-report
+          path: playwright-report/
+```
+
+---
+
+## NEVER Do
+
+1. **NEVER use fixed `waitForTimeout()` or `cy.wait(ms)`** — they cause flaky tests and slow down suites
+2. **NEVER rely on CSS classes or DOM structure for selectors** — use roles, labels, or data-testid
+3. **NEVER share state between tests** — each test must be completely independent
+4. **NEVER test implementation details** — test what users see and do, not internal structure
+5. **NEVER skip cleanup** — always delete test data you created, even on failure
+6. **NEVER test everything with E2E** — reserve for critical paths; use faster tests for edge cases
+7. **NEVER ignore flaky tests** — fix them immediately or delete them; a flaky test is worse than no test
+8. **NEVER hardcode test data in selectors** — use dynamic waits for content that varies
+
