This section summarizes the options available in `spring-test` for Spring MVC applications.

* Servlet API Mocks: Mock implementations of Servlet API contracts for unit testing controllers, filters, and
other web components. See <<testing.adoc#mock-objects-servlet,Servlet API>> mock objects
for more details.

* TestContext Framework: Support for loading Spring configuration in JUnit and TestNG tests, including efficient
caching of the loaded configuration across test methods and support for loading a
`WebApplicationContext` with a `MockServletContext`.
See <<testing.adoc#testcontext-framework,TestContext Framework>> for more details.

* Spring MVC Test: A framework, also known as `MockMvc`, for testing annotated controllers through the
`DispatcherServlet` (that is, supporting annotations), complete with the Spring MVC
infrastructure but without an HTTP server. See
<<testing.adoc#spring-mvc-test-framework,Spring MVC Test>> for more details.

* Client-side REST: `spring-test` provides a `MockRestServiceServer` that you can use as a mock server for
testing client-side code that internally uses the `RestTemplate`.
See <<testing.adoc#spring-mvc-test-client,Client REST Tests>> for more details.

* `WebTestClient`: Built for testing WebFlux applications, but it can also be used for
end-to-end integration testing, to any server, over an HTTP connection. It is a
non-blocking, reactive client and is well suited for testing asynchronous and streaming
scenarios.
