automate a test case API side
First read the documentation (functional requirement)
of the application understand each endpoints including
authentication authorization and other relevant information
like query params, headers, expected status codes and response body,
response headers. Test it out manually in Postman to
get results for both positive negatives responses.
Write test scenarios and assertions around those expected
outcomes according to the doc. I can write both in Postman
and RestAssured. Latest project I worked on RestAssured
Maven project
