How to do acceptance test automatically for full system? [on hold]

I'm practicing TDD and I want to do Acceptance-Test automatically. Here are my questions.

1. Is there any way to do Acceptance-Test automatically(not mocking, I want to test in real)? Assumption

   • client - server1 - server2

2. then how to do it?

3. Could you recommend Acceptance-Test tool (like postman)?

4. If Acceptance-Test tool doesn't exist, then how can I implement it?

Thanks!
