Verification Tests

Test 1: URL Validation

Check Implementation:

// File should exist: /Users/eddiebelaval/Development/id8/id8composer-rebuild/src/lib/billing/validation.ts
// Should export: isValidReturnUrl(url: string): boolean

Test Cases:

1. Valid URL (same origin) → should return true
2. External URL → should return false
3. javascript: URL → should return false
4. data: URL → should return false
5. Malformed URL → should return false

Verification Command:

cd /Users/eddiebelaval/Development/id8/id8composer-rebuild
npm test -- validation.test.ts

Test 2: Price ID Validation

Check Implementation:

// File: src/lib/billing/validation.ts
// Should export: isValidPriceId(priceId: string): boolean
// Should validate against env vars

Test Cases:

1. Valid PRO monthly price ID → true
2. Valid PRO annual price ID → true
3. Valid ENTERPRISE price ID → true
4. Invalid/unknown price ID → false
5. Empty string → false

Test 3: Rate Limiting

Check Implementation:

// Files modified:
// - src/app/api/billing/checkout/route.ts
// - src/app/api/billing/portal/route.ts
// Should use rate limiter middleware

Test Manually:

# Make 6 rapid requests to checkout endpoint
TOKEN="your_test_token"
for i in {1..6}; do
  RESPONSE=$(curl -s -o /dev/null -w "%{http_code}" -X POST \
    http://localhost:3000/api/billing/checkout \
    -H "Authorization: Bearer $TOKEN" \
    -H "Content-Type: application/json" \
    -d '{"priceId":"price_test","returnUrl":"http://localhost:3000/billing"}')
  echo "Request $i: HTTP $RESPONSE"
done

# Expected: First 5 return 200/400, 6th returns 429
