## 🎨 Visual Regression Testing
|
||||
|
||||
### Overview
|
||||
|
||||
Visual regression testing ensures UI consistency across browsers and prevents unintended visual changes.
|
||||
|
||||
### Screenshots Generated
|
||||
|
||||
- **Full page screenshots** (mobile, tablet, desktop)
|
||||
- **Component screenshots** (hero, logo wall, cards, etc.)
|
||||
- **Interactive states** (hover, focus, loading, error)
|
||||
- **Special modes** (dark mode, high contrast, reduced motion)
|
||||
|
||||

||||
branches: [main, develop]
|
||||
```
|
||||
|
||||
## 🛠 Development Workflow
|
||||
|
||||
### 1. Feature Development
|
||||
|
||||
```bash
|
||||
# Create feature branch
|
||||
git checkout -b feature/new-component
|
||||
|
||||
# Write tests first (TDD)
|
||||
npm run test:watch
|
||||
|
||||
# Implement feature
|
||||
# Ensure tests pass
|
||||
|
||||
# Run E2E tests
|
||||
npm run e2e
|
||||
|
||||
# Commit changes
|
||||
git add .
|
||||
git commit -m "feat: add new component with tests"
|
||||
```
|
||||
|
||||
### 2. Pull Request Process
|
||||
|
||||
1. **Create PR** → CI pipeline starts automatically
|
||||
2. **Review CI Results** → All 7 jobs must pass
|
||||
3. **Check Coverage** → Ensure >85% coverage
|
||||
4. **Review Visual Changes** → Check screenshot diffs
|
||||
5. **Merge** → Only if all checks pass
|
||||
|
||||
### 3. Visual Changes
|
||||
|
||||
```bash
|
||||
# Make visual changes
|
||||
# Run visual regression tests
|
||||
npm run e2e:serve
|
||||
npx playwright test tests/e2e/visual-regression.spec.ts
|
||||
|
||||
# If changes are intentional, update baselines
|
||||
npx playwright test tests/e2e/visual-regression.spec.ts --update-snapshots
|
||||
```
|
||||
|
||||
### 4. Performance Monitoring
|
||||
|
||||
```bash
|
||||
# Check performance before deploying
|
||||
npm run lhci
|
||||
|
||||
# Review performance budgets
|
||||
# Update lighthouserc.json if needed
|
||||
```
|
||||
|
||||
## 📋 Best Practices
|
||||
|
||||
### 1. Test-Driven Development
|
||||
|
||||
- Write tests before implementation
|
||||
- Use descriptive test names
|
||||
- Test edge cases and error scenarios
|
||||
- Maintain high test coverage
|
||||
|
||||
### 2. Component Testing
|
||||
|
||||
```jsx
|
||||
// Good: Test behavior, not implementation
|
||||
test("shows error message when form is invalid", () => {
|
||||
render(<Form />);
|
||||
fireEvent.click(screen.getByRole("button"));
|
||||
expect(screen.getByText("Please fill all fields")).toBeInTheDocument();
|
||||
});
|
||||
|
||||
// Avoid: Testing implementation details
|
||||
test("calls onSubmit with form data", () => {
|
||||
const mockSubmit = vi.fn();
|
||||
render(<Form onSubmit={mockSubmit} />);
|
||||
// Implementation details...
|
||||
});
|
||||
```
|
||||
|
||||
### 3. E2E Testing
|
||||
|
||||
- Test user workflows, not technical details
|
||||
- Use semantic selectors (role, text, label)
|
||||
- Test accessibility features
|
||||
- Include error scenarios
|
||||
|
||||
### 4. Visual Regression
|
||||
|
||||
- Update baselines only for intentional changes
|
||||
- Review screenshot diffs carefully
|
||||
- Test across multiple viewports
|
||||
- Consider animation states
|
||||
|
||||
### 5. Performance Testing
|
||||
|
||||
- Set realistic performance budgets
|
||||
- Monitor Core Web Vitals
|
||||
- Test on different network conditions
|
||||
- Regular performance audits
|
||||
|
||||
## 🔧 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### 1. Unit Tests Failing
|
||||
|
||||
```bash
|
||||
# Run tests locally
|
||||
npm test
|
||||
|
||||
# Check for:
|
||||
# - Missing imports
|
||||
# - Incorrect assertions
|
||||
# - Component changes
|
||||
# - Test environment issues
|
||||
```
|
||||
|
||||
#### 2. E2E Tests Failing
|
||||
|
||||
```bash
|
||||
# Run locally first
|
||||
npm run e2e:serve
|
||||
npm run e2e
|
||||
|
||||
# Common issues:
|
||||
# - Selector changes
|
||||
# - Component structure changes
|
||||
# - Network issues
|
||||
# - Browser compatibility
|
||||
```
|
||||
|
||||
#### 3. Visual Regression Failing
|
||||
|
||||
```bash
|
||||
# Check if changes are intentional
|
||||
npx playwright test tests/e2e/visual-regression.spec.ts
|
||||
|
||||
# Update baselines if needed
|
||||
npx playwright test tests/e2e/visual-regression.spec.ts --update-snapshots
|
||||
|
||||
# Review screenshot diffs in CI artifacts
|
||||
```
|
||||
|
||||
#### 4. Performance Tests Failing
|
||||
|
||||
```bash
|
||||
# Run locally
|
||||
npm run lhci
|
||||
|
||||
# Check performance budgets in lighthouserc.json
|
||||
# Optimize slow components
|
||||
# Review bundle size
|
||||
```
|
||||
|
||||
#### 5. CI Pipeline Issues
|
||||
|
||||
```bash
|
||||
# Check Gitea Actions logs
|
||||
# Verify workflow configuration
|
||||
# Check for missing dependencies
|
||||
# Review environment variables
|
||||
```

## 📝 Writing Tests
|
||||
|
||||
### Unit Test Template
|
||||
|
||||
```jsx
|
||||
// tests/unit/Component.test.jsx
|
||||
import { render, screen } from "@testing-library/react";
|
||||
import { describe, test, expect, afterEach } from "vitest";
|
||||
import { cleanup } from "@testing-library/react";
|
||||
import Component from "../../app/components/Component";
|
||||
|
||||
describe("Component", () => {
|
||||
afterEach(() => cleanup());
|
||||
|
||||
test("renders correctly", () => {
|
||||
render(<Component />);
|
||||
expect(screen.getByRole("button")).toBeInTheDocument();
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### E2E Test Template
|
||||
|
||||
```typescript
|
||||
// tests/e2e/feature.spec.ts
|
||||
import { test, expect } from "@playwright/test";
|
||||
|
||||
test.describe("Feature", () => {
|
||||
test.beforeEach(async ({ page }) => {
|
||||
await page.goto("/");
|
||||
});
|
||||
|
||||
test("should work correctly", async ({ page }) => {
|
||||
await expect(page).toHaveTitle(/CommunityRule/);
|
||||
await expect(page.locator("h1")).toBeVisible();
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## 🔧 Common Testing Patterns
|
||||
|
||||
### Testing User Interactions
|
||||
|
||||
```jsx
|
||||
// Unit test
|
||||
import userEvent from "@testing-library/user-event";
|
||||
|
||||
test("handles user input", async () => {
|
||||
const user = userEvent.setup();
|
||||
render(<Form />);
|
||||
|
||||
await user.type(screen.getByLabelText("Email"), "test@example.com");
|
||||
await user.click(screen.getByRole("button", { name: "Submit" }));
|
||||
|
||||
expect(screen.getByText("Success")).toBeInTheDocument();
|
||||
});
|
||||
```
|
||||
|
||||
### Testing Async Operations
|
||||
|
||||
```jsx
|
||||
// Unit test
|
||||
test("loads data", async () => {
|
||||
render(<DataComponent />);
|
||||
|
||||
expect(screen.getByText("Loading...")).toBeInTheDocument();
|
||||
|
||||
await waitFor(() => {
|
||||
expect(screen.getByText("Data loaded")).toBeInTheDocument();
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Testing Accessibility
|
||||
|
||||
```typescript
|
||||
// E2E test
|
||||
import { runA11y } from "./axe";
|
||||
|
||||
test("meets accessibility standards", async ({ page }) => {
|
||||
await page.goto("/");
|
||||
const violations = await runA11y(page);
|
||||
expect(violations).toEqual([]);
|
||||
});
|
||||
```
|
||||

## 🚨 Common Issues & Solutions
|
||||
|
||||
### Unit Tests
|
||||
|
||||
```bash
|
||||
# Issue: JSX not parsing in .js files
|
||||
# Solution: Ensure vitest.config.js has proper esbuild config
|
||||
|
||||
# Issue: Component not rendering
|
||||
# Solution: Check imports and component exports
|
||||
|
||||
# Issue: Test cleanup errors
|
||||
# Solution: Add afterEach(cleanup()) to test suites
|
||||
```
|
||||
|
||||
### E2E Tests
|
||||
|
||||
```bash
|
||||
# Issue: Element not found
|
||||
# Solution: Use semantic selectors (role, text, label)
|
||||
|
||||
# Issue: Test timeout
|
||||
# Solution: Add proper waitFor or waitForLoadState
|
||||
|
||||
# Issue: Multiple elements with same selector
|
||||
# Solution: Use .first(), .nth(), or more specific selectors
|
||||
```
|
||||
|
||||
### Visual Regression
|
||||
|
||||
```bash
|
||||
# Issue: Screenshots don't match
|
||||
# Solution: Check if changes are intentional, then update baselines
|
||||
|
||||
# Issue: Elements not visible
|
||||
# Solution: Ensure elements are in viewport before screenshot
|
||||
```
