![]() ![]() The second file is the Postman environment - primarily used to enable fast switching between different configurations e.g. The first file is the Postman collection - this contains all the individual requests and tests and as such is the main file within the test suite. JSON Placeholder Env.postman_environment.json.JSON Placeholder.postman_collection.json.The Postman test suite here is made up of two separate files: The API has no authorisation/authentication applied so that aspect is not tested here. Some of these resources are related to one another e.g., posts have comments, albums have photos, users make posts etc. The API has six endpoints across a number of different types: The API tested here is the JSON Placeholder API, a free fake API for testing and prototyping. developers and QA), or significant mocking functionality is required then a paid plan will be necessary. As more collaboration between team members (e.g. That same plan will also support a significant expansion of the current test suite and creation of further test suites for other APIs (the number of APIs and requests that can be made is unlimited in the free tier), so it remains a cost-effective option for API testing. This tier is adequate for this test suite i.e. Postman has a free tier to their pricing plan which allows up to 3 users to access the basic functionality. I want to show how more detailed tests can be written - and easily maintained - within Postman. Often people use the code snippets to perform simple response code checks but may not go beyond this. There is no support for other languages, and the Postman syntax can be a little strange if you're not used to it, even if you're an experienced JavaScript coder but at the same time there are a number of code snippets provided within Postman to help you create your tests. Postman tests are written using JavaScript and the Chai assertion library. ![]() However, Postman is capable of much more and is often overlooked as an automated API testing tool. It is simple to build & send requests and examine the responses, making it popular for exploratory and manual testing of APIs. Postman is a popular and easy-to-use API testing tool. It is an example of how to structure a Postman test suite but only a subset of the requests (tests) have been added. NB This is not a complete implementation of a Postman test suite for the target API. It can be used to kickstart testing of other REST APIs with minimal changes to the project. This project provides an example for testing REST APIs with Postman. ![]()
