Testing on different environments? No Problem! You also have the freedom to manipulate the data that you receive, courtesy of the assertions written in JavaScript. For each of these tests, that are run in a specific order, an HTTP request is made and the assertions written in JavaScript are used to verify the integrity of the code. In order to ensure that your API is working as expected, Postman tool allows you to create collections of integration tests. Why Postman? Test Suites - Create them with ease With the native Postman application performing better than the Postman Chrome app, and the process of migrating being easy (takes less than minute!), it is time to say Goodbye to Postman extension and switch to their native apps. The new Postman native apps covered all the features & functionalities of the postman chrome extension, and in many cases, the native app was even better than the original Chrome app. In response to the deprecation of Postman Google Chrome extension, they introduced native apps for Windows, Mac and Linux users and encouraged their users to begin the migration. This is something that happened when Google announced their not-so-great plans to end support for Chrome apps for Windows, Mac & Linux users. Download our free native apps for continued support & better performance." However, if you are still using the Postman Google Chrome app, you may notice a banner on top which says "Chrome apps are being deprecated. Over the years, the API ecosystem evolved, and with this the Postman native apps' capabilities were also improved to surpass the performance of the postman chrome extension. The Google Postman extension was widely accepted and was one of the most sought after tool for testing. The postman started out as a Postman Chrome App when it first came out, used along with the Postman Interceptor Chrome extension. Postman’s complete API development platform will allow you to create requests, build and manage collections, and govern the complete life cycle of your APIs. Postman can be accessed through native apps for MacOS, Linux and Windows. Postman allows you to design, mock, debug, automatically test, document, monitor and publish the APIs - everything from one place. The Postman testing tool is a complete API development platform with various built-in tools that support every stage of the API lifecycle. Postman allows you to organize your API requests into collections and folders share common values across requests with environment variables, script tests with the built-in node.js based runtime, and automate it all with its very own CLI – Newman. But deep down, Postman is built on an extensive set of powerful tools that are very easy to use. Make Testing Easier With Postman ToolĪt the first glance, Postman testing tool is a simple GUI for sending HTTP requests and viewing responses. As the prime motive of creating an API is to enable other applications to use the services, every stage of the API development process requires testing for functionality, exception handling and security. The REST framework sets a set of guidelines that should be followed while creating an API. For example, the social newspaper Frrole uses the Twitter API to generate contextual insights by analyzing a large volume of tweets.Īlthough there are a number of ways in which an API can be created, a Web API is usually created by using the REST (Representational State Transfer) framework. A mobile application of an ecommerce website uses an API Anything with a social login uses an API even the ads that you see on the Internet use APIs!īy creating an API for your service, you enable third-party developers to create applications based on your service. If you look around on the Internet, you can see that a very large number of services use APIs.
