SecurityMockMvcResultMatchers

At times it is desirable to make various security related assertions about a request. To accommodate this need, Spring Security Test support implements Spring MVC Test’s ResultMatcher interface. In order to use Spring Security’s ResultMatcher implementations ensure the following static import is used:

  • Java

  • Kotlin

import static org.springframework.security.test.web.servlet.response.SecurityMockMvcResultMatchers.*;
import org.springframework.security.test.web.servlet.response.SecurityMockMvcResultMatchers.*

Unauthenticated Assertion

At times it may be valuable to assert that there is no authenticated user associated with the result of a MockMvc invocation. For example, you might want to test submitting an invalid username and password and verify that no user is authenticated. You can easily do this with Spring Security’s testing support using something like the following:

  • Java

  • Kotlin

mvc
	.perform(formLogin().password("invalid"))
	.andExpect(unauthenticated());
mvc
    .perform(formLogin().password("invalid"))
    .andExpect { unauthenticated() }

Authenticated Assertion

It is often times that we must assert that an authenticated user exists. For example, we may want to verify that we authenticated successfully. We could verify that a form based login was successful with the following snippet of code:

  • Java

  • Kotlin

mvc
	.perform(formLogin())
	.andExpect(authenticated());
mvc
    .perform(formLogin())
    .andExpect { authenticated() }

If we wanted to assert the roles of the user, we could refine our previous code as shown below:

  • Java

  • Kotlin

mvc
	.perform(formLogin().user("admin"))
	.andExpect(authenticated().withRoles("USER","ADMIN"));
mvc
    .perform(formLogin())
    .andExpect { authenticated().withRoles("USER","ADMIN") }

Alternatively, we could verify the username:

  • Java

  • Kotlin

mvc
	.perform(formLogin().user("admin"))
	.andExpect(authenticated().withUsername("admin"));
mvc
    .perform(formLogin().user("admin"))
    .andExpect { authenticated().withUsername("admin") }

We can also combine the assertions:

  • Java

  • Kotlin

mvc
	.perform(formLogin().user("admin"))
	.andExpect(authenticated().withUsername("admin").withRoles("USER", "ADMIN"));
mvc
    .perform(formLogin().user("admin"))
    .andExpect { authenticated().withUsername("admin").withRoles("USER", "ADMIN") }

We can also make arbitrary assertions on the authentication

  • Java

  • Kotlin

mvc
	.perform(formLogin())
	.andExpect(authenticated().withAuthentication(auth ->
		assertThat(auth).isInstanceOf(UsernamePasswordAuthenticationToken.class)));
mvc
    .perform(formLogin())
    .andExpect {
        authenticated().withAuthentication { auth ->
            assertThat(auth).isInstanceOf(UsernamePasswordAuthenticationToken::class.java) }
        }
    }
