Considering it, which frequently get noticed, Postman being the best Open Source tool, has a feature to manage this in less time with automation and we will be a great idea to go to use the requests againĭistinguish the environment that you need to define. To run the requests successfully now we have to make the changes to every request included in those 200 requests, which consumes a lot of time. Since postman collections can have numerous requests inside it, imagine a scenario in which the URL changes, for instance, they change their server API URL specific to the environment(UAT or PROD) and update the tester regarding it.įor example, if there are some 200 requests, we want to change multiple times. Each server has various kinds of API requests. These can be Staging, UAT, or PROD servers. We regularly experience various servers in our organization. Problem Statement Solution & Implementation Continuous Integration – Development processes can be properly maintained with continuous integration support.Data Debugging – Postman console helps check what data has been retrieved making it simpler to debug.Process Automation – Through the use of the Collection Runner or Newman, tests can be run in multiple iterations saving time for repetitive tests.Creating Test Cases – Test checklists such as verifying for successful HTTP response status can be added to each API call which will help ensure test coverage.Establishing Environments – Having multiple environment statuses helps in less repetition of tests as one can use the same collection for a different environment.A Simple link can also be used to share collections. Combination – Collections and environments can be easily imported or exported to share files.This helps in organizing your test suites. Each collection can create subfolders and multiple requests. Collection Usage – Postman allows users to create collections for API calls.Accessibility – To access, one would just need to login to their own account making it easy to access files anytime, anywhere as long as a Postman application is installed. ![]() The following features have helped Postman become an effective tool of choice: We will use Fiddler throughout this tutorial series.How postman has become an effective tool for API Testing Thus, you can use Postman to test your Web API.
