title: How to install mock server and pact files for API testing?
body: <p>I'm new to API testing. I read few documents and tutorials about this topic. However I am not able to understand how to use &amp; install the mock server and create the files to test the APIs. Can anyone help me with this? Moreover can anyone suggest me which tools are better to test a full roundtrip (backend &amp; frontend) for APIs?</p>
