This enables developers to execute and monitor the API requests they sent and the results they received, making it a great tool for developers, testers, and end consumers to understand the endpoints they are testing. This UI presentation of the APIs is user-friendly and easy to understand, with all the logical complexity kept behind the screen. Swagger UI, a part of Swagger, is an open source tool that generates a web page that documents the APIs generated by the Swagger specification. This makes it great for testing and debugging API problems. This means that not only can this be shared with your team internally, but the same documentation can be used to automate API-dependent processes.

Swagger (now known as the OpenAPI Initiative, under the structure of the Linux Foundation) is a framework for describing your API by using a common language that is easy to read and understand for developers and testers, even if they have weak source code knowledge.


We will start by discussing what Swagger UI is, why it's worth using, and then move on to the tutorial. In this article, I will show you how to use Swagger UI for API testing.
