Remain API Test is an API client that makes it easy for developers to test OpenApi requests. This is done by allowing users to create and save simple and complex HTTP/s requests, as well as reading and validating their responses.

Remain API Test is integrated with Remain API Studio to make it easy to test the oas3 files. The tests can be saved and replayed. Tests can also put in test cases. This makes API testing more efficient and less tedious.

Requests are the core functionality of the Remain API Test. We can create a new request by right-clicking on requests to open the request editor. We can then select the HTTP method to use, specify the URL for the request and configure parameters, headers, and body of requests.
