+Spring's MVC Test framework can also be used to make a request to a Springfox Swagger endpoint during an unit test. A custom ResultHandler ``Swagger2MarkupResultHandler`` can be used to write the Swagger JSON response into a directory. The custom ResultHandler is part of ``springfox-staticdocs``. That way you also verify that your Swagger endpoint is working.

 The quickest way to get started is to look at the demo project https://github.com/Swagger2Markup/spring-swagger2markup-demo[spring-swagger2markup-demo]. The demo shows how to generate static docs (HTML5 and PDF) with the Swagger2Markup Gradle Plugin and serve them as static content in a Spring Boot App under http://localhost:9080/docs/index.html and http://localhost:9080/docs/index.pdf.
