- Implement CrowdSec integration tests to validate DDoS/bot protection mechanisms. - Create rate limiting tests to ensure request throttling and proper handling of rate limit headers. - Develop security enforcement tests to check JWT validation, CSRF protection, request timeouts, and middleware execution order.

/**
|
|
* Phase 3 - CrowdSec Integration Tests
|
|
*
|
|
* Validates that CrowdSec module correctly enforces DDoS/bot protection:
|
|
* - Normal requests allowed → 200 OK
|
|
* - After CrowdSec ban triggered → 403 Forbidden
|
|
* - Whitelist bypass (test IP) allows requests → 200 OK
|
|
* - Decision list populated (>0 entries)
|
|
* - Bot detection headers (User-Agent spoofing) → potential 403
|
|
* - Cache consistency across requests
|
|
*
|
|
* Total Tests: 12
|
|
* Expected Duration: ~10 minutes
