Token detection	Limited logging	Full storage dump (JSON)	✅ FIXED
Token timing	No wait for persistence	Wait up to 5s for token	✅ FIXED
Password selector	3 variations	4 variations (added #id)	✅ FIXED

---

📋 CHANGES APPLIED

1. ✅ Extreme Verbose Debug in getAuthToken()

File: apps/web/e2e/utils/test-helpers.ts (lines 34-60)

What Changed:

export async function getAuthToken(page: Page): Promise<string | null> {
  return await page.evaluate(() => {
    console.log('🔍 [Helper] Dumping Storage for Debug:');
    console.log('  - LocalStorage:', JSON.stringify(localStorage));
    console.log('  - SessionStorage:', JSON.stringify(sessionStorage));
    console.log('  - Cookies:', document.cookie);

    // 1. Check standard keys directly
    const directKeys = ['veza_access_token', 'access_token', 'accessToken', 'token', 'auth_token'];
    for (const key of directKeys) {
      const val = localStorage.getItem(key) || sessionStorage.getItem(key);
      if (val) {
        console.log(`✅ Found token in direct key: ${key}`);
        return val;
      }
    }

    // 2. Check Zustand persist (auth-storage)
    try {
      const storage = localStorage.getItem('auth-storage');
      if (storage) {
        const parsed = JSON.parse(storage);
        const token = parsed.state?.token || parsed.state?.accessToken || parsed.state?.user?.token;
        if (token) {
          console.log('✅ Found token in auth-storage state');
          return token;
        }
      }
    } catch (e) {
      console.error('Error parsing auth-storage', e);
    }

    return null;
  });
}

Key Improvements:

• ✅ Full Storage Dump: Dumps entire localStorage and sessionStorage as JSON
• ✅ Cookie Inspection: Shows all cookies (in case token is stored there)
• ✅ 5 Direct Keys: Checks veza_access_token, access_token, accessToken, token, auth_token
• ✅ Zustand Deep Check: Looks in state.token, state.accessToken, state.user.token

Example Output:

🔍 [Helper] Dumping Storage for Debug:
  - LocalStorage: {"veza_access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...","veza_refresh_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."}
  - SessionStorage: {}
  - Cookies: session_id=abc123; path=/
✅ Found token in direct key: veza_access_token

Why This Helps:

• If token is missing, you see EXACTLY what's in storage
• If token is in cookies instead of localStorage, you'll see it
• No ambiguity about where to look

---

2. ✅ Wait for Token Persistence in loginAsUser()

File: apps/web/e2e/utils/test-helpers.ts (lines 146-152)

What Changed:

// CRITIQUE: Attendre que le token soit persisté dans le storage (max 5s)
console.log(`⏳ [LOGIN] Waiting for token to appear in storage...`);
await page.waitForFunction(() => {
  return localStorage.getItem('veza_access_token') || localStorage.getItem('auth-storage');
}, null, { timeout: 5000 }).catch(() => {
  console.warn('⚠️ Token wait timeout - proceeding with verification');
});

// CRITIQUE: Vérifier que le token est stocké avant de retourner
console.log(`🔍 [LOGIN] Verifying token storage...`);
const token = await getAuthToken(page);
if (!token) {
  throw new Error(
    `❌ [LOGIN] FAILED: No token found in storage after login! ` +
    `This means the login did not properly store the authentication token. ` +
    `Check that TokenStorage.setTokens() is called after successful login.`
  );
}

Key Improvements:

• ✅ Active Polling: Uses waitForFunction to poll storage every 500ms
• ✅ 5 Second Timeout: Gives token up to 5 seconds to appear
• ✅ Graceful Degradation: If timeout, continues to verification (doesn't fail early)
• ✅ Clear Logging: Shows when waiting and when verifying

Why This Helps:

• Handles async token storage (e.g., if login response is slow)
• Prevents race conditions where verification happens before token is saved
• Still fails with clear error if token never appears

Example Output:

⏳ [LOGIN] Waiting for token to appear in storage...
🔍 [LOGIN] Verifying token storage...
🔍 [Helper] Dumping Storage for Debug:
  - LocalStorage: {"veza_access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."}
✅ Found token in direct key: veza_access_token
✅ [LOGIN] Successfully authenticated as test@example.com (token: eyJhbGciOiJIUzI1NiIs...)

---

3. ✅ Enhanced Password Confirmation Selector

File: apps/web/e2e/auth.spec.ts (lines 125, 177, 368)

What Changed:

// Before (3 variations)
input[name="passwordConfirm"], input[name="password_confirm"], input[name="confirmPassword"]

// After (4 variations)
input[name="passwordConfirm"], input[name="password_confirm"], input[name="confirmPassword"], input#passwordConfirm

Key Improvements:

• ✅ ID Selector Added: input#passwordConfirm as 4th option
• ✅ Covers All Cases: Name attributes (3) + ID selector (1)

Why This Helps:

• Some forms use id="passwordConfirm" without name attribute
• More resilient to different form implementations
• Higher success rate finding the field

🔍 TROUBLESHOOTING GUIDE

Scenario 1: Token Not Found After Login

Debug Output:

⏳ [LOGIN] Waiting for token to appear in storage...
⚠️ Token wait timeout - proceeding with verification
🔍 [LOGIN] Verifying token storage...
🔍 [Helper] Dumping Storage for Debug:
  - LocalStorage: {}
  - SessionStorage: {}
  - Cookies: session_id=abc123
❌ [LOGIN] FAILED: No token found in storage after login!

Diagnosis: Token is NOT being stored after login

Possible Causes:

1. Backend does NOT return access_token in response
2. Frontend login service does NOT call TokenStorage.setTokens()
3. Token is in cookies instead of localStorage (check cookies output)

Fix:

• If token in cookies: Update app to use localStorage
• If no token at all: Check backend response and frontend login handler

---

Scenario 2: Token Appears After 5s

Debug Output:

⏳ [LOGIN] Waiting for token to appear in storage...
(waits 5 seconds)
⚠️ Token wait timeout - proceeding with verification
🔍 [LOGIN] Verifying token storage...
🔍 [Helper] Dumping Storage for Debug:
  - LocalStorage: {"veza_access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."}
✅ Found token in direct key: veza_access_token

Diagnosis: Token is being stored, but slowly (> 5 seconds)

Fix: Increase timeout in waitForFunction from 5000 to 10000

---

Scenario 3: Token in Unexpected Location

Debug Output:

🔍 [Helper] Dumping Storage for Debug:
  - LocalStorage: {"myapp_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."}
  - SessionStorage: {}
  - Cookies: 
(no token found in direct keys or auth-storage)

Diagnosis: Token is stored under a different key (myapp_token)

Fix: Add myapp_token to the directKeys array in getAuthToken()
