**Status:** COMPLETE
**Commit:** `2d1b0da95`
**Date:** 2026-02-05

---

## Overview

Successfully implemented Phase 2, Task 2 of the Comprehensive Test Validation Plan. This task creates WebSocket CORS validation E2E tests with comprehensive log collection, custom Playwright reporting, and test user infrastructure integration.

---

## Files Created

### 1. WebSocket Validation Test Suite
**File:** `/frontend/apps/web/e2e/websocket-validation.spec.ts`

**Purpose:** Validates WebSocket CORS implementation and connection handling

**Test Coverage:**
- `should establish WebSocket connection with CORS headers` - Verifies CORS headers are present and correct
- `should authenticate via WebSocket after connection` - Tests WebSocket authentication flow
- `should handle WebSocket reconnection gracefully` - Tests reconnection logic with event tracking
- `should include proper CORS headers in WebSocket upgrade request` - Verifies upgrade request headers
- `should not expose sensitive data in WebSocket logs` - Security test for log privacy

**Key Features:**
- Console log capture with type and location tracking
- Network request interception for /ws endpoints
- Page error collection
- Sensitive data pattern detection (passwords, tokens, API keys)
- Flexible CORS header validation (supports various localhost ports)

**Size:** 160 lines of TypeScript

---

### 2. Custom Playwright Reporter
**File:** `/frontend/apps/web/e2e/reporters/failed-routes-reporter.ts`

**Purpose:** Generates comprehensive JSON report of failed routes during E2E testing

**Features:**
- **Failed Routes Tracking:** Extracts URLs from test titles and tracks failures
- **Test Result Details:** Captures status, error messages, duration, retries for each test
- **Summary Statistics:**
  - Total tests run
  - Pass/fail/skip/timeout counts
  - Total duration and wall-clock time
  - Sorted list of failed routes
- **Output:** Generates `playwright-report/failed-routes.json` with full results
- **Console Summary:** Prints formatted summary to console for CI/CD visibility

**Data Structure:**
```typescript
{
  timestamp: string;           // ISO timestamp
  wallClock: number;           // Total execution time
  totalDuration: number;       // Sum of test durations
  summary: {
    total: number;
    passed: number;
    failed: number;
    skipped: number;
    timedout: number;
  };
  failedRoutes: string[];      // Sorted array of failed URLs
  details: TestResultDetail[]; // Full test results
}
```

**Size:** 98 lines of TypeScript

---

## Files Modified

### 1. Test Helpers - Log Collection Functions
**File:** `/frontend/apps/web/e2e/fixtures/test-helpers.ts`

**Additions:**

#### BrowserLogs Interface
```typescript
interface BrowserLogs {
  console: Array<{ level: string; message: string; timestamp: number }>;
  errors: Array<{ message: string; stack?: string; timestamp: number }>;
  warnings: string[];
}
```

#### NetworkLog Interface
```typescript
interface NetworkLog {
  url: string;
  status: number;
  method: string;
  headers: Record<string, string>;
  timing: number;
}
```

#### collectBrowserLogs Function
- Captures console messages with level and timestamp
- Captures page errors with stack traces
- Returns structured BrowserLogs object
- Used throughout WebSocket validation tests

#### collectNetworkLogs Function
- Captures HTTP response details
- Tracks URL, status code, method, headers, timing
- Returns array of NetworkLog entries
- Enables network analysis in test assertions

**Impact:** +41 lines added (preserving existing TestHelpers class and utilities)

---

### 2. Playwright Configuration
**File:** `/frontend/apps/web/playwright.config.ts`

**Modifications:**
```typescript
reporter: [
  ['html', { outputFolder: 'playwright-report' }],
  ['json', { outputFile: 'playwright-report/results.json' }],
  ['junit', { outputFile: 'playwright-report/junit.xml' }],
  ['list'],
  // Custom reporter for failed routes
  [require.resolve('./e2e/reporters/failed-routes-reporter.ts')],
]
```

**Changes:**
- Added JUnit reporter for CI/CD integration
- Registered custom failed-routes-reporter for JSON output
- Maintains existing HTML and JSON reporters

**Impact:** Enhanced reporting for failed route tracking and multi-format test results

---

### 3. Global Setup with Test User Context
**File:** `/frontend/apps/web/e2e/global-setup.ts`

**Enhancements:**
- Sets test user email: `kooshapari@kooshapari.com`
- Sets test user password: `testAdmin123`
- Stores test user info in environment variables:
  - `TEST_USER_EMAIL`
  - `TEST_USER_PASSWORD`
  - `TEST_USER_FIRST_NAME`
  - `TEST_USER_LAST_NAME`
- Initializes context for all subsequent tests
- Includes placeholder comments for future integrations:
  - Mock API server startup
  - Test database seeding
  - Authentication token generation

**Impact:** +34 lines added (creates persistent test user context)

## Architecture

### Log Collection Flow

```
Page Events
├── console messages → collectBrowserLogs
├── page errors      → collectBrowserLogs
└── network requests → collectNetworkLogs

Test Execution
├── Capture logs during test
├── Perform assertions
└── Log results to console

Reporting
├── HTML Report (Playwright native)
├── JSON Report (Playwright native)
├── JUnit Report (CI/CD integration)
└── Failed Routes JSON (custom reporter)
```

### Test User Integration

```
Global Setup
└── Initialize TEST_USER_* environment variables
    └── Available to all tests via process.env
        └── Can be overridden by environment or Makefile targets
```

### Custom Reporter Flow

```
onTestEnd (per test)
└── Extract URL from test title
└── Track if failed
└── Store full result details

onEnd (after all tests)
└── Generate summary statistics
└── Write failed-routes.json
└── Print formatted console output
```

---

## Test Execution

### Run WebSocket Validation Tests Locally

cd frontend/apps/web
bun run test:e2e -- websocket-validation.spec.ts
```

## Integration Points

### 1. Caddyfile CORS Fix Validation
Tests validate that Caddyfile.dev includes proper WebSocket CORS headers:
```
Access-Control-Allow-Origin: http://localhost:4000 (or matching origin)
Access-Control-Allow-Credentials: true
```

### 2. Test User Context
Global setup initializes test user that will be used in:
- Phase 2, Task 3: Route validation tests
- Phase 3, Task 4: Vitest API tests
- Phase 4, Task 5: Go backend tests
- Phase 5, Task 6: Pytest backend tests

### 3. CI/CD Integration
Multiple output formats support various CI/CD tools:
- **GitHub Actions:** JUnit report for native GitHub integration
- **Custom CI:** JSON report for parsing and analysis
- **Local Development:** HTML report for interactive review
