But wait, that’s manual, isn’t it? Yes, we need to test automatically, because in the 21st Century manual testing is… no, I will not comment on that.Īs a first step, we need to export our Collection to a JSON file in Postman format. Ok, let’s say we finished collecting our tests together, what’s next? We can easily rerun them as many times as we need.
The power behind this is JS, making is quite easy to write many tests for specific coverage, including schema validation for a JSON response body, and much more. Now we can make sure that our API GET request is responding with the 401 HTTP code. With a slight change, it looks like this: tests = de = 401 When using JavaScript in Postman (you can also use other languages), there are some predefined JavaScript code widgets that should be used. Tests = postman.getResponseHeader("WWW-Authenticate") Ī couple of words about the tests. Tests = postman.getResponseHeader("Server").has("nginx/1.10.1") Tests = postman.getResponseHeader("Server") Tests = postman.getResponseHeader("Connection").has("keep-alive") Tests = postman.getResponseHeader("Connection") Tests = postman.getResponseHeader("Date") Tests = responseBody.has("Unauthorized") Postman.cleanGlobalVariable("variable_key") In this collection we should include all the API tests we created for this sample API. Creating a Postman Collectionįirst of all we need to create our first collection in Postman. Using Newman allows teams to integrate API test automation into Continuous Integration tools. Newman is a command line executor for Postman tests, enabling you to make Postman's open-source API testing tool more powerful by running a Postman collection from the command line. Integrating Newman & Postman Into CI Systems.To do that, I will test a sample API from Postman, which is a simple GET request.

In this blog post I will show you how to use Newman + Postman. It also provides lots of useful functionalities on top of the main HTTP requests like API documentation, monitoring, and simulating a mock server. Postman is a tool for sending requests to API endpoints.
