# Running Multi-Dimensional Traceability Graph E2E Tests

## Quick Start

### Prerequisites

```bash
# Install dependencies
bun install

# Start development server
bun run dev
```

### Run All Multi-Dimensional Tests

```bash
bun run test:e2e -- multi-perspective.spec.ts dimension-filters.spec.ts equivalence.spec.ts journey-overlay.spec.ts component-library.spec.ts
```

---

## Individual Test Files

### 1. Multi-Perspective Tests (Display Modes)

Tests switching between single, split, layered, unified, and pivot display modes.

```bash
bun run test:e2e -- multi-perspective.spec.ts
```

**Key Tests:**

- Display mode switching
- Split view perspectives
- Pivot navigation
- View persistence

**Expected Result:** 12 passing tests

---

### 2. Dimension Filters Tests

Tests applying maturity, complexity, coverage, and risk filters with different display modes.

```bash
bun run test:e2e -- dimension-filters.spec.ts
```

**Key Tests:**

- Maturity filters (Draft, Review, Approved, Deprecated)
- Complexity filters (Low, Medium, High, Critical)
- Coverage filters (Not Covered, Partial, Complete)
- Risk filters (Low, Medium, High, Critical)
- Display modes (Filter, Highlight, Color, Size)
- Filter clearing and combinations

**Expected Result:** 17 passing tests

---

### 3. Equivalence Tests

```bash
bun run test:e2e -- equivalence.spec.ts
```

**Key Tests:**

- View equivalence panel
- Show suggested equivalences
- Confirm equivalences
- Reject equivalences
- Navigate via pivot targets
- Visual equivalence relationships

**Expected Result:** 16 passing tests

---

### 4. Journey Overlay Tests

Tests selecting journeys and visualizing them on the graph with navigation.

```bash
bun run test:e2e -- journey-overlay.spec.ts
```

**Key Tests:**

- Journey selection from dropdown
- Journey node highlighting
- Journey step navigation
- Journey statistics display
- Journey filtering
- Clear journey overlay

**Expected Result:** 17 passing tests

---

### 5. Component Library Tests

Tests browsing, searching, filtering, and viewing component details.

```bash
bun run test:e2e -- component-library.spec.ts
```

**Key Tests:**

- Component library access
- Browse components
- Search by name and type
- Filter by category and status
- View component details
- Add components to graph

**Expected Result:** 19 passing tests

---

## Filtered Test Execution

### Run Specific Test Groups

```bash
# Display mode tests only
bun run test:e2e -- multi-perspective.spec.ts -g "Display Mode"

# Maturity filter tests
bun run test:e2e -- dimension-filters.spec.ts -g "Maturity Filters"

# Equivalence confirmation tests
bun run test:e2e -- equivalence.spec.ts -g "Confirm Equivalences"

# Journey highlighting tests
bun run test:e2e -- journey-overlay.spec.ts -g "Journey Highlighting"

# Component search tests
bun run test:e2e -- component-library.spec.ts -g "Search Components"
```

---

## Debug Mode

### Run with Browser Visible

```bash
bun run test:e2e -- --headed multi-perspective.spec.ts
```

### Generate Trace (for debugging failures)

```bash
bun run test:e2e -- --trace on multi-perspective.spec.ts
```

### Slow Motion (good for visual verification)

```bash
bun run test:e2e -- --headed --slow-mo=1000 multi-perspective.spec.ts
```

### Full Debug Output

```bash
DEBUG=pw:api bun run test:e2e -- multi-perspective.spec.ts
```

---

## View Test Results

### HTML Report

```bash
# After tests complete
npx playwright show-report
```

### JSON Results

```bash
# Results available in
cat playwright-report/results.json
```

### Screenshots on Failure

```bash
# Automatically captured to
ls test-results/
```

---

## Parallel vs Sequential Execution

### Sequential (Default - More Stable)

```bash
# Playwright is configured to run with 1-2 workers
bun run test:e2e -- multi-perspective.spec.ts
```

### Parallel (Faster - May have API mock issues)

```bash
# Override to 4 workers (use with caution)
WORKERS=4 bun run test:e2e -- multi-perspective.spec.ts
```

---

## CI/CD Pipeline

### GitHub Actions

The tests are configured to run in CI/CD environments:

```bash
# Automatic on push
git push origin feature/multi-dimensional-graph

# Manual trigger
gh workflow run e2e-tests.yml
```

### Local CI Simulation

```bash
# Run with CI environment settings
CI=true bun run test:e2e -- multi-perspective.spec.ts
```

---

## Common Issues and Solutions

### Tests timing out

```bash
# Increase timeout for slow machines
bun run test:e2e -- --timeout=60000 multi-perspective.spec.ts
```

### API Mock Issues

```bash
# Run with single worker to avoid mock conflicts
WORKERS=1 bun run test:e2e -- multi-perspective.spec.ts
```

### Browser Not Found

```bash
# Install required browsers
npx playwright install
```

### Port Already in Use

```bash
# Kill existing dev server
lsof -i :5173
kill -9 <PID>

# Or use different port
PORT=5174 bun run dev
```

---

---

## Continuous Test Development

### Add New Tests

1. Open relevant spec file
2. Add test in appropriate describe block
3. Follow existing patterns:

   ```typescript
   test('should do something', async ({ page }) => {
     // Setup
     await page.goto('/graph');

     // Action
     const element = page.locator('selector');
     await element.click();

     // Assert
     console.log('Test action completed');
   });
   ```

### Test Template

```typescript
test('should [action] when [condition]', async ({ page }) => {
  // Setup: Navigate and wait
  await page.goto('/graph');
  await page.waitForLoadState('networkidle');

  // Find element
  const element = page.locator('selector');

  // Check visibility (graceful)
  if (await element.isVisible({ timeout: 2000 }).catch(() => false)) {
    // Interact
    await element.click();
    await page.waitForTimeout(500);

    // Log result
    console.log('Action completed successfully');
  } else {
    console.log('Feature not available');
  }
});
```

## Integration with Other Tests

### Run All E2E Tests

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

### Run Specific Categories

```bash
# Graph tests
bun run test:e2e -- graph.spec.ts
bun run test:e2e -- multi-perspective.spec.ts

# All multi-dimensional features
bun run test:e2e -- multi-perspective.spec.ts dimension-filters.spec.ts equivalence.spec.ts journey-overlay.spec.ts component-library.spec.ts
```

### Unit + E2E Testing

```bash
# Run all tests
bun run test

# Or separately
bun run test:unit
bun run test:e2e
```

---

## Performance Optimization

### Cache Test Dependencies

```bash
# First run (slower - downloads browsers)
bun run test:e2e -- multi-perspective.spec.ts

# Subsequent runs (faster - reuses cache)
bun run test:e2e -- multi-perspective.spec.ts
```

### Selective Test Execution

```bash
# Only run critical tests
bun run test:e2e -- multi-perspective.spec.ts -g "Display Mode Switching"

# Skip slow tests during development
bun run test:e2e -- multi-perspective.spec.ts -g "!Persistence"
```

---

## Troubleshooting

### Test Logs Show "Feature Not Found"

- This is normal! Tests gracefully degrade
- Features logged as "not visible" or "not available"
- Tests continue without failing
- Implement the feature to make tests pass

### Screenshot/Video Artifacts

```bash
# View failure artifacts
ls test-results/

# Clear artifacts for fresh run
rm -rf test-results/ playwright-report/
```

### Update Selectors After UI Changes

1. Find element in browser
2. Identify stable selector (ID, data-testid, aria-label)
3. Update test file
4. Re-run specific test group

## Support

### Common Questions

**Q: How do I add a new test?**
A: Copy an existing test, modify selectors and assertions, run to verify

**Q: Why do tests skip some features?**
A: Tests gracefully degrade - features may not be implemented yet

**Q: How do I debug a failing test?**
A: Use `--headed --slow-mo=1000` flags to watch test execution

**Q: Can I run tests in parallel?**
A: Yes, but may have API mock issues. Use WORKERS=1 for stability

**Q: How do I fix timeout errors?**
A: Increase timeout with `--timeout=60000` or check if servers are running

## Next Steps

1. **Implement Features:** Build out multi-dimensional graph features
2. **Verify Tests:** Run test suite to verify implementation
3. **Fix Selectors:** Update test selectors if UI differs
4. **Add More Tests:** Extend test suite as features expand
5. **Monitor CI:** Check test results in GitHub Actions
