Spring Security provides support for running tests as a specific user. For example, the test in the snippet below will run with an authenticated user that has the ADMIN role.

@Test
@WithMockUser(roles="ADMIN")
public void requestProtectedUrlWithUser() throws Exception {
	mvc
		.perform(get("/"))
		...
}

Spring Security provides comprehensive integration with Spring MVC Test and this can also be used when testing controllers using the @WebMvcTest slice and MockMvc.

For additional details on Spring Security’s testing support, refer to Spring Security’s reference documentation).
