Annotation that can be applied to a test class to enable and configure auto-configuration of Spring REST Docs. The auto-configuration sets up MockMvc-based testing of a servlet web application, WebTestClient-based testing of a reactive web application, or RestAssured-based testing of any web application over HTTP. 
 Allows configuration of the output directory and the host, scheme, and port of generated URIs. When further configuration is required a RestDocsMockMvcConfigurationCustomizer, RestDocsWebTestClientConfigurationCustomizer, or RestDocsRestAssuredConfigurationCustomizer bean can be used.
