+
+## Mock Utilities
+
+### Development Mode vs Production Mode
+
+The tests automatically detect the environment:
+
+- **Development Mode** (`!process.env.PLAYWRIGHT_URL`): Uses mocks for all API calls
+- **Production Mode** (`process.env.PLAYWRIGHT_URL`): Uses real API endpoints
+
+### Using Mock Utilities
+
+```typescript
+import {
+  setupOptimizationMocks,
+  mockOptimizationsResponse,
+} from './utils/devMode';
+
+test.beforeEach(async ({ page }) => {
+  if (devMode) {
+    // Setup all mocks at once
+    await setupOptimizationMocks(page);
+
+    // Or setup specific mocks
+    await mockOptimizationsResponse(page, customOptimizations);
+  }
+});
+```
+
+### Available Mock Functions
+
+#### `devMode.ts`
+
+- `setupOptimizationMocks(page)` - Setup all mocks for basic testing
+- `mockClustersResponse(page, clusters)` - Mock clusters API
+- `mockOptimizationsResponse(page, optimizations, status)` - Mock optimizations API
+- `mockEmptyOptimizationsResponse(page)` - Mock empty optimizations
+- `mockWorkflowExecutionResponse(page, execution, status)` - Mock workflow execution
+- `mockAuthTokenResponse(page, token)` - Mock authentication
+- `mockAccessCheckResponse(page, hasAccess)` - Mock access check
+- `mockAuthGuestRefreshResponse(page)` - Mock guest token refresh
+- `mockPermissionResponse(page, hasPermission)` - Mock permission checks
+- `mockCostManagementResponse(page, data)` - Mock cost management API
+- `mockEmptyCostManagementResponse(page)` - Mock empty cost management data
+- `mockCostManagementErrorResponse(page, status)` - Mock cost management errors
+
+#### `apiUtils.ts`
+
+- `waitUntilApiCallSucceeds(page, urlPart)` - Wait for API success
+- `mockApiEndpoint(page, urlPattern, responseData, status)` - Generic API mock
+- `mockApiError(page, urlPattern, errorMessage, status)` - Mock API errors
+- `verifyApiCallMade(page, urlPattern, method)` - Verify API calls
+
+## Page Objects
+
+### ResourceOptimizationPage
+
+Encapsulates all interactions with the optimization plugin UI:
+
+```typescript
+const optimizationPage = new ResourceOptimizationPage(page);
+
+// Navigation
+await optimizationPage.navigateToOptimization();
+
+// Cluster selection
+await optimizationPage.selectCluster('Production Cluster');
+
+// View optimizations
+await optimizationPage.viewOptimizations();
+
+// Apply recommendations
+await optimizationPage.applyRecommendation('opt-1');
+
+// Verify states
+await optimizationPage.verifyOptimizationDisplayed(optimization);
+await optimizationPage.expectEmptyState();
+await optimizationPage.expectErrorState();
+```
+
+## Test Data
+
+### Mock Data Structure
+
+The `fixtures/optimizationResponses.ts` file contains realistic mock data:
+
+```typescript
+export const mockOptimizations = [
+  {
+    id: 'opt-1',
+    clusterId: 'cluster-1',
+    workloadName: 'frontend-deployment',
+    resourceType: 'CPU',
+    currentValue: '2000m',
+    recommendedValue: '1000m',
+    savings: { cost: 45.5 },
+    status: 'pending',
+    severity: 'medium',
+    // ... more fields
+  },
+  // ... more optimizations
+];
+```
+
+## Running Tests
+
+### Local Development
+
+```bash
+# Run all tests
+yarn test:e2e
+
+# Run specific test file
+yarn playwright test optimization.test.ts
+
+# Run with UI
+yarn test:e2e:ui
+
+# Run in headed mode
+yarn test:e2e:headed
+```
+
+### CI Environment
+
+Tests automatically run in CI when changes are made to the optimization plugin workspace.
+
+## Environment Variables
+
+For production mode testing, set these environment variables:
+
+```bash
+export PLAYWRIGHT_URL=http://localhost:3000
+export RHHCC_SA_CLIENT_ID=your-client-id
+export RHHCC_SA_CLIENT_SECRET=your-client-secret
+```
+
+## Writing New Tests
+
+1. **Use page objects** for UI interactions
+2. **Mock API calls** in development mode
+3. **Test both success and error scenarios**
+4. **Validate accessibility** with proper ARIA labels
+5. **Use descriptive test names** that explain the user journey
+
+### Example Test Structure
+
+```typescript
+test('should handle optimization workflow', async ({ page }) => {
+  // Setup
+  if (devMode) {
+    await mockOptimizationsResponse(page, testOptimizations);
+    await mockWorkflowExecutionResponse(page, successExecution);
+  }
+
+  // Action
+  await optimizationPage.navigateToOptimization();
+  await optimizationPage.selectCluster('test-cluster');
+  await optimizationPage.viewOptimizations();
+  await optimizationPage.applyRecommendation('opt-1');
+
+  // Verification
+  await optimizationPage.expectWorkflowSuccess();
+});
+```
+
+## Configuration
+
+The plugin requires these configurations in `app-config.yaml`:
+
+```yaml
+proxy:
+  endpoints:
+    '/cost-management/v1':
+      target: https://console.redhat.com/api/cost-management/v1
+      allowedHeaders: ['Authorization']
+      credentials: dangerously-allow-unauthenticated
+
+resourceOptimization:
+  clientId: ${RHHCC_SA_CLIENT_ID}
+  clientSecret: ${RHHCC_SA_CLIENT_SECRET}
+  optimizationWorkflowId: 'patch-k8s-resource'
+```
