Disable Spring Security config class for @WebMvcTest in Spring Boot

You can set secure=false in the @WebMvcTest annoation. It will skip the spring security MockMvc auto configuration in your Test

@WebMvcTest(controllers = SomeController.class, secure = false)
public class SomeControllerTest {

Note by the author: As of 2021, this answer has been obsolete for a few years and it probably won't work for you.

For me in Spring Boot 2.2.4 (JUnit5) the below seems to have worked and bypass the security filter.

@ExtendWith(SpringExtension.class)
@WebMvcTest(SomeController.class)
@AutoConfigureMockMvc(addFilters = false)
public class SomeControllerTest {
...

Note: this simply disables any filters in the SpringSecurity configuration. It won't disable the security completely. In other words it will still bootstrap security without loading any filters.
