When you open the webpage, the browser will load the webpage from the web server, and trigger requests to the API server to get data from the database. Swagger UI represents APIs within the browser, so I find it more intuitive than other tools such as Postman, SoapUI, and others. 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. It's human-readable and machine-readable.Product managers, partners, and even potential clients can have input into the design of your API because they can see it clearly mapped out in the friendly UI. It's comprehensible for developers and non-developers.Swagger has certain benefits compared with other frameworks, such as: You can use whatever building materials you like, but you can't step outside the parameters of the blueprint. You can think of it as a blueprint for a house. 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. A Springfox Docket instance provides the primary API configuration with sensible defaults and convenience methods for configuration.In this article, I will show you how to use Swagger UI for API testing. Once you have the pom.xml in place, you can create a package for config and use the below code. īelow is the complete pom.xml which I have used. To configure Swagger, you need the below 3 dependencies in your pom.xml.
