Have you ever worked with Postman tool for API testing?

Yes, I have worked with Postman for API testing. This tool allows creating and sending HTTP requests to a server, checking responses, and automating tests. For example, you can set up a collection of requests with different parameters and use scripts to verify the correctness of responses.

A simple test example in Postman:

pm.test("Response status is 200", function () {
    pm.response.to.have.status(200);
});

This helps ensure that the API returns a successful response.
