= Setting Up MockMvc and Spring Security

[NOTE]
====
Spring Security's testing support requires spring-test-4.1.3.RELEASE or greater.
====

To use Spring Security with Spring MVC Test, add the Spring Security `FilterChainProxy` as a `Filter`.
You also need to add Spring Security's `TestSecurityContextHolderPostProcessor` to support xref:servlet/test/mockmvc/setup.adoc#test-mockmvc-withmockuser[Running as a User in Spring MVC Test with Annotations].
To do so, use Spring Security's `SecurityMockMvcConfigurers.springSecurity()`:

====
.Java
[source,java,role="primary"]
----

import static org.springframework.security.test.web.servlet.setup.SecurityMockMvcConfigurers.*;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SecurityConfig.class)
@WebAppConfiguration
public class CsrfShowcaseTests {

	@Autowired
	private WebApplicationContext context;

	private MockMvc mvc;

	@Before
	public void setup() {
		mvc = MockMvcBuilders
				.webAppContextSetup(context)
				.apply(springSecurity()) // <1>
				.build();
	}
	// ...
}
----

.Kotlin
[source,kotlin,role="secondary"]
----
@RunWith(SpringJUnit4ClassRunner::class)
@ContextConfiguration(classes = [SecurityConfig::class])
@WebAppConfiguration
class CsrfShowcaseTests {

    @Autowired
    private lateinit var context: WebApplicationContext

    private var mvc: MockMvc? = null

    @Before
    fun setup() {
        mvc = MockMvcBuilders
            .webAppContextSetup(context)
            .apply<DefaultMockMvcBuilder>(springSecurity()) // <1>
            .build()
    }
    // ...
}
----
<1> `SecurityMockMvcConfigurers.springSecurity()` will perform all of the initial setup we need to integrate Spring Security with Spring MVC Test
