MockServer

An HTTP mock and proxy server for integration testing. Define request expectations with custom responses, record and replay traffic, and verify that your systems send the correct requests.

What You Can Do After Deployment

1. Visit your domain — open the MockServer dashboard UI
2. Create expectations — define mock responses for specific request patterns
3. Send requests — point your application or tests at MockServer
4. Verify requests — confirm that expected requests were received
5. Inspect traffic — review all captured requests and responses in the dashboard
