For the latest stable version, please use Spring Security 6.4.2!

Setting Up MockMvc and Spring Security

In order to use Spring Security with Spring MVC Test it is necessary to add the Spring Security FilterChainProxy as a Filter. It is also necessary to add Spring Security’s TestSecurityContextHolderPostProcessor to support Running as a User in Spring MVC Test with Annotations. This can be done using Spring Security’s SecurityMockMvcConfigurers.springSecurity(). For example:

Spring Security’s testing support requires spring-test-4.1.3.RELEASE or greater.

Java
Kotlin

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

@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = SecurityConfig.class)
@WebAppConfiguration
public class CsrfShowcaseTests {

	@Autowired
	private WebApplicationContext context;

	private MockMvc mvc;

	@BeforeEach
	public void setup() {
		mvc = MockMvcBuilders
				.webAppContextSetup(context)
				.apply(springSecurity()) (1)
				.build();
	}

...

@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = [SecurityConfig::class])
@WebAppConfiguration
class CsrfShowcaseTests {

    @Autowired
    private lateinit var context: WebApplicationContext

    private var mvc: MockMvc? = null

    @BeforeEach
    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
