If you downloaded the collection above, this should already appear in the sidebar. Installation is via npm, but before we can run it, we need a file from Postman. If we’re honest, that just means that none of this will get used after we’ve spent so much time on it. This is all well and good, but opening Postman is an extra step to your existing tests. They show you several ways you can measure how your API behaves and performs. Not pictured in these examples are Postman’s examples to the right of your test code. If this were our own API, we would go further and make similar assertions about HTTP status codes and the expected failure responses our API generates. In this case, we assert that the API must include an id element in the response. Then you can pass it a description and set its value by making an assertion about some aspect of the response. Postman builds a collection called tests that takes a description and a boolean value, which it will display for us. Clicking the “Tests” button off to the right of “Send” opens a text box where we can write some javascript. I don’t want to look at the response every time I make a request, so I’m going to have Postman look at the response to make sure it has the element we want in it. Postman pretty-prints the response, and it looks like Google’s API is working. This is what Postman should look like once that has been set up. Let’s construct a request and make sure Google’s response actually gives us a short URL. Google’s URL shortener expects a single parameter enclosed in a JSON document. If you already have Jetpacks, you can follow the example here-be sure to click the import tab in Postman and use the Download from link tab to import the collection. This makes it extremely valuable for functional testers or for developers who love to test outside-in. While they won’t replace your focused unit tests, they do breathe new life into testing features from outside your applications. This post will walk you through an example that uses those testing features. The people behind Postman also offer an add-on package called Jetpacks, which includes some automation tools and, most crucially, a Javascript testing library. It presents you with a friendly GUI for constructing requests and reading responses. Postman is a Google Chrome app for interacting with HTTP APIs. #Google chrome postman download how to#Let’s take a look at how to use Newman to get more out of Postman. ![]() The people behind Postman have released a command-line tool for running Postman collections called Newman. One admittedly huge advantage these other methods have had for me in the past is the ability to integrate them with my regular testing tools-but no more. As a tool to setup complex HTTP requests, it’s much more convenient than request specs, Cucumber, or hand-rolling them in even your favorite HTTP library. I’ve used Postman on a few projects as a way to interact with APIs that I’m writing. ![]()
