# E2E Tests for TraceRTM

End-to-end tests using Playwright for critical user flows in the TraceRTM application.

## Setup

Playwright is already installed and configured. The tests use MSW (Mock Service Worker) for API mocking, so they can run without a backend server.

## Running Tests

### All E2E Tests

```bash
bun run test:e2e
```

### Interactive UI Mode (Recommended for Development)

```bash
bun run test:e2e:ui
```

### Headed Mode (See Browser)

```bash
bun run test:e2e:headed
```

### Debug Mode

```bash
bun run test:e2e:debug
```

### View Test Report

```bash
bun run test:e2e:report
```

### Run All Tests (Unit + E2E)

```bash
bun run test:all
```

## Test Strategy

### MSW Integration

All tests run with MSW enabled, which means:

- No backend server required
- Consistent mock data across tests
- Fast test execution
- Offline testing capability

### Soft Assertions

Many tests use soft assertions (`.catch()`) to handle:

- UI elements that may not be implemented yet
- Different UI patterns across views
- Feature flags or conditional rendering

This approach allows tests to:

- Pass even if some features are incomplete
- Provide helpful console logs for missing features
- Serve as documentation for expected functionality

### Test Coverage

Current E2E test coverage focuses on:

- ✅ Navigation flows
- ✅ CRUD operations (Projects, Items)
- ✅ Dashboard functionality
- ✅ Different view modes (Table, Kanban, Tree)
- ✅ Search and filtering
- ✅ Basic authentication flows

## Test Data

### Mock Data (Production)

Tests use the mock data defined in `src/mocks/data.ts`:

- **2 Projects**: "TraceRTM Core" and "Mobile App"
- **10 Items**: Requirements, features, code, tests, APIs, etc.
- **7 Links**: Traceability links between items
- **3 Agents**: Code analyzer, test runner, documentation generator

### Test Fixtures

Test-specific data is available in `e2e/fixtures/`:

**`testData.ts`**: Test data generators and utilities

- Pre-defined test projects, items, links, and agents
- Form input data templates
- Search queries and filter values
- Validation and success message patterns
- Helper functions for generating test data
- Mock API response builders

**`pageHelpers.ts`**: Reusable page interaction functions

- Navigation helpers (navigateToProjects, navigateToItems, etc.)
- Command palette helpers (openCommandPalette, searchInCommandPalette)
- Form helpers (fillProjectForm, fillItemForm, submitForm)
- Dialog helpers (confirmDialog, cancelDialog, closeDialog)
- Search and filter helpers
- CRUD operation helpers
- Assertion helpers
- Keyboard navigation helpers
- Offline mode helpers
- Local storage and cookie helpers

**Usage Example:**

```typescript
import { generateTestProject, navigateToProjects, fillProjectForm } from './fixtures';

test('create project with helper', async ({ page }) => {
  const projectData = generateTestProject({ name: 'My Test Project' });
  await navigateToProjects(page);
  await fillProjectForm(page, projectData);
  await submitForm(page);
});
```

## Configuration

The Playwright configuration is in `playwright.config.ts`:

- **Test directory**: `./e2e`
- **Base URL**: `http://localhost:5173`
- **Browser**: Chromium (default)
- **Timeout**: 30 seconds per test
- **Retries**: 2 on CI, 0 locally
- **Reporter**: HTML, JSON, and list
- **Dev server**: Automatically starts Vite dev server

## Writing New Tests

### Test Template

```typescript
import { test, expect } from '@playwright/test';

test.describe('Feature Name', () => {
  test.beforeEach(async ({ page }) => {
    await page.goto('/route');
    await page.waitForLoadState('networkidle');
  });

  test('should do something', async ({ page }) => {
    // Arrange
    const button = page.getByRole('button', { name: /click me/i });

    // Act
    await button.click();

    // Assert
    await expect(page).toHaveURL('/expected-route');
  });
});
```

### Best Practices

1. **Use semantic selectors**: Prefer `getByRole`, `getByLabel`, `getByText` over CSS selectors
2. **Wait for load states**: Use `waitForLoadState('networkidle')` after navigation
3. **Soft assertions**: Use `.catch()` for optional UI elements
4. **Console logs**: Add helpful logs for skipped tests or missing features
5. **Test isolation**: Each test should be independent and clean up after itself

### Common Patterns

#### Waiting for Elements

```typescript
// Wait for specific text
await page.waitForSelector('text=/Expected Text/', { timeout: 5000 });

// Wait for element to be visible
const element = page.getByRole('button', { name: /Submit/i });
await expect(element).toBeVisible({ timeout: 5000 });
```

#### Handling Optional Elements

```typescript
const optionalButton = page.getByRole('button', { name: /Optional/i });
if (await optionalButton.isVisible({ timeout: 2000 })) {
  await optionalButton.click();
} else {
  console.log('Optional feature not available');
}
```

#### Form Interactions

```typescript
// Fill input
await page.getByLabel(/Name/i).fill('Test Name');

// Select from dropdown
await page.getByLabel(/Type/i).click();
await page.getByText('Option Value').click();

// Submit form
await page.getByRole('button', { name: /Submit/i }).click();
await page.waitForLoadState('networkidle');
```

## Debugging

### View Test in Browser

```bash
bun run test:e2e:headed
```

### Debug Specific Test

```bash
bunx playwright test auth.spec.ts --debug
```

### View Trace

After a test failure, traces are automatically captured:

```bash
bunx playwright show-trace trace.zip
```

### Screenshots and Videos

- Screenshots: Captured on failure
- Videos: Retained on failure
- Location: `test-results/` directory

## CI/CD Integration

The tests are configured to run in CI with:

- Headless mode
- 2 retries
- Single worker (no parallel execution)
- HTML and JSON reports

Add to your CI pipeline:

```yaml
- name: Run E2E Tests
  run: bun run test:e2e
```

## Troubleshooting

### Tests Timing Out

- Increase timeout in `playwright.config.ts`
- Use `waitForLoadState('networkidle')` after navigation
- Check for slow API responses (MSW delays)

### Elements Not Found

- Verify element exists in the UI
- Check selector accuracy (use Playwright Inspector)
- Use `page.locator('selector').first()` for multiple matches
- Add soft assertions with `.catch()` for optional elements

### MSW Not Working

- Verify `VITE_ENABLE_MSW=true` in `.env.local`
- Check MSW handlers in `src/mocks/handlers.ts`
- Look for `[MSW] Mock Service Worker started` in console

### Dev Server Not Starting

- Kill any process on port 5173
- Check Vite configuration
- Verify `package.json` scripts
