+# Known Deprecation Warnings
+
+## DEP0060: util._extend Deprecation Warning
+
+When running the frontend development server with `yarn start:stage`, you may encounter the following deprecation warning:
+
+```code
+(node:xxxxx) [DEP0060] DeprecationWarning: The `util._extend` API is deprecated. Please use Object.assign() instead.
+    at ProxyServer.<anonymous> (/Users/.../node_modules/http-proxy/lib/http-proxy/index.js:50:26)
+    at HttpProxyMiddleware.middleware (/Users/.../node_modules/http-proxy-middleware/dist/http-proxy-middleware.js:22:32)
+```
+
+### What causes this warning?
+
+This warning originates from the `http-proxy@1.18.1` library, which is a transitive dependency used by:
+
+- `webpack-dev-server@5.2.2` (our dev dependency)
+- `http-proxy-middleware@2.0.9` (dependency of webpack-dev-server)
+
+The `http-proxy` library still uses the deprecated `util._extend()` API instead of the modern `Object.assign()`.
+
+### Is this harmful?
+
+**No, this warning is completely harmless:**
+
+- The functionality works exactly the same
+- `util._extend()` still functions correctly in all supported Node.js versions
+- This is purely a deprecation notice, not an error
+- It does not affect the application's functionality or performance
+
+### When will this be fixed?
+
+This will be resolved when:
+
+1. The upstream `http-proxy` library is updated to use `Object.assign()` instead of `util._extend()`
+2. OR when `webpack-dev-server` switches to a different proxy implementation
+3. OR when we upgrade to newer versions that have resolved this issue
+
+### React 19 Compatibility
+
+This deprecation warning will not prevent upgrading to React 19 or any future React versions, as it's unrelated to React and only affects the development server's proxy functionality.
+
+### Alternative Solutions Considered
+
+1. **Patching the library**: We could patch `http-proxy` to use `Object.assign()`, but this adds maintenance overhead
+2. **Suppressing warnings**: We could use `NODE_OPTIONS='--no-deprecation'` to hide all deprecation warnings, but this might hide other important warnings
+3. **Yarn resolutions**: We could try to force a different version, but `1.18.1` is already the latest
+
+For now, we've decided to leave the warning visible as it's informational and doesn't impact functionality.

+# Treeherder Puppeteer Tests Inventory
+
+This document provides a comprehensive inventory of all Puppeteer-based integration tests in the Treeherder project, detailing what functionality each test covers and how they are organized.
+
+## Overview
+
+Treeherder uses Puppeteer for end-to-end integration testing to ensure the web application works correctly in a real browser environment. These tests complement the unit tests by validating complete user workflows and cross-component interactions.
+
+### Test Framework Configuration
+
+- **Framework**: Jest + Puppeteer
+- **Configuration**: [`jest-puppeteer.config.js`](../jest-puppeteer.config.js)
+- **Environment**: Headless Chrome (configurable)
+- **HTTP Recording**: Polly.js for request/response mocking
+- **Test Location**: [`tests/ui/integration/`](../tests/ui/integration/)
+- **Timeout**: 60 seconds per test
+- **Server**: Automatically starts development server (`yarn start`)
+
+### Running Tests
+
+```bash
+# Run all integration tests
+npm run test:integration
+
+# Run specific test file
+npm run test:integration -- --testPathPattern="jobs_view"
+
+# Run tests in watch mode
+npm run test:integration -- --watch

+
+## Running Integration Tests
+
+Integration tests are excluded from the regular Jest test suite and must be run separately:
+
+```bash
+# Run all integration tests
+npm run test:integration
+
+# Run specific test file
+npm run test:integration -- --testPathPattern="jobs_view"
+
+# Run tests in watch mode
+npm run test:integration -- --watch
+```
+
+## Test Configuration
+
+### Jest Configuration
+
+- **Configuration**: [`jest-puppeteer.config.js`](../../../jest-puppeteer.config.js)
+- **Environment**: Puppeteer with headless Chrome
+- **Server**: Automatically starts development server (`yarn start`)
+- **Timeout**: 60 seconds per test
+
+### HTTP Request Recording
+
+Tests use [Polly.js](https://netflix.github.io/pollyjs/) to record and replay HTTP requests:
+
+- Recordings are stored in the `recordings/` directory as HAR files
+- First test run records real HTTP requests
+- Subsequent runs replay recorded requests for consistency
+- Set `recordIfMissing: true` to update recordings when needed
+
+## Test Categories
+
+### 1. Jobs View Tests (`jobs-view/`)
+
+Tests the main Treeherder jobs interface:
+
+- **Navigation**: Repository switching, URL parameter handling
+- **Filtering**: Search, result status, field filters
+- **Job Selection**: Job details panel, job actions
+- **Push List**: Push information, job group expansion
+- **Keyboard Shortcuts**: Shortcut modal, key bindings
+- **URL Handling**: Deep linking, parameter persistence
+
+### 2. Push Health Tests (`push-health/`)
+
+Tests the push health analysis interface:
+
+- **Navigation**: Landing page, usage documentation
+- **Health Analysis**: Revision-specific health data
+- **Test Results**: Failure information, job metrics
+- **Interaction**: Test group expansion, result filtering
+- **My Pushes**: User-specific push data
+- **Error Handling**: Invalid revisions, missing parameters
+- **Performance**: Loading indicators, response times
+
+### 3. Navigation Tests (`navigation/`)
+
+Tests cross-application navigation and routing:
+
+- **Cross-App Navigation**: Jobs ↔ Perfherder ↔ Push Health
+- **URL Compatibility**: Legacy URL redirects, hash parameters
+- **Error Handling**: 404 pages, malformed URLs
+- **Browser Navigation**: Back/forward buttons, page refresh
+- **Authentication**: Login callbacks, auth flows
+- **Documentation**: User guide, API docs
+- **Responsive**: Mobile and tablet viewports
+
+### 4. Graphs View Tests (`graphs-view/`)
+
+Existing tests for Perfherder graphs functionality:
+
+- **Modal Interactions**: Add test data modal
+- **View Toggling**: Table view ↔ Graphs view
+- **HTTP Recording**: Request/response recording with Polly.js
+
+## Test Utilities
+
+The [`helpers/test-utils.js`](helpers/test-utils.js) file provides common utilities:
+
+### Setup Functions
+
+- `setupIntegrationTest(testName)` - Complete test setup with Polly.js
+- `setupPollyForTest(testName)` - HTTP recording setup only
+
+### Navigation Helpers
+
+- `navigateAndWaitForLoad(page, url, options)` - Navigate and wait for page ready
+- `waitForLoadingComplete(page, options)` - Wait for loading indicators to disappear
+
+### Element Interaction
+
+- `clickElement(page, selector, options)` - Click with retry logic
+- `typeIntoField(page, selector, text, options)` - Type into input fields
+- `waitForClickableElement(page, selector, options)` - Wait for interactive elements
+
+### Content Verification
+
+- `waitForTextContent(page, selector, expectedText, options)` - Wait for specific text
+- `getTextContent(page, selector)` - Extract text content
+- `getAttribute(page, selector, attribute)` - Get element attributes
+- `isElementVisible(page, selector)` - Check element visibility
+
+## Writing New Tests
+
+### Basic Test Structure
+
+```javascript
+import { setupIntegrationTest } from '../helpers/test-utils';
+
+describe('My Feature Tests', () => {
+  const {
+    context,
+    navigateAndWaitForLoad,
+    clickElement,
+    // ... other helpers
+  } = setupIntegrationTest('MyFeature');
+
+  test('should do something', async () => {
+    await navigateAndWaitForLoad(`${URL}/my-feature`);
+    
+    await clickElement('.my-button');
+    
+    // Assertions...
+  });
+});
+```
+
+### Best Practices
+
+1. **Use Descriptive Test Names**: Clearly describe what functionality is being tested
+2. **Wait for Elements**: Always wait for elements before interacting with them
+3. **Handle Async Operations**: Use appropriate wait functions for loading states
+4. **Test Error States**: Include tests for error conditions and edge cases
+5. **Keep Tests Independent**: Each test should be able to run in isolation
+6. **Use Page Object Pattern**: For complex pages, consider creating page object helpers
+7. **Mock External Dependencies**: Use Polly.js recordings to avoid external API dependencies
+
+### Common Patterns
+
+```javascript
+// Wait for page to load
+await navigateAndWaitForLoad(`${URL}/jobs`);
+
+// Wait for specific content
+await waitForTextContent('.status', 'Success');
+
+// Check if element exists
+const hasButton = await isElementVisible('.action-button');
+if (hasButton) {
+  await clickElement('.action-button');
+}
+
+// Handle loading states
+await waitForLoadingComplete();
+
+// Verify URL changes
+await page.waitForFunction(
+  () => window.location.search.includes('param=value'),
+  { timeout: 10000 }
+);
+```
+
+## Debugging Tests
+
+### Running Tests in Non-Headless Mode
+
+Modify [`jest-puppeteer.config.js`](../../../jest-puppeteer.config.js):
+
+```javascript
+module.exports = {
+  launch: {
+    headless: false, // Set to false to see browser
+    slowMo: 250,     // Slow down actions for debugging
+  },
+  // ...
+};
+```
+
+### Adding Debug Information
+
+```javascript
+// Take screenshots for debugging
+await page.screenshot({ path: 'debug-screenshot.png' });
+
+// Log page content
+const content = await page.content();
+console.log(content);
+
+// Log console messages
+page.on('console', msg => console.log('PAGE LOG:', msg.text()));
+```
+
+### Common Issues
+
+1. **Timeouts**: Increase timeout values for slow-loading content
+2. **Element Not Found**: Ensure selectors match actual DOM structure
+3. **Race Conditions**: Use proper wait functions instead of fixed delays
+4. **Network Issues**: Check Polly.js recordings for HTTP request problems
+5. **Authentication**: Some features may require login state
+
+## Maintenance
+
+### Updating Recordings
+
+When API responses change, update recordings by:
+
+1. Delete relevant files in `recordings/` directory
+2. Run tests to generate new recordings
+3. Commit updated recording files
+
+### Adding New Test Suites
+
+1. Create new directory under `tests/ui/integration/`
+2. Add test files with descriptive names
+3. Use `setupIntegrationTest()` for consistent setup
+4. Update this README with new test descriptions
+
+### Performance Considerations
+
+- Integration tests are slower than unit tests
+- Run integration tests in CI but not on every commit
+- Consider parallel test execution for large test suites
+- Monitor test execution time and optimize slow tests
