Mocking Spring Security Context for Unit Testing
Today, while writing unit test case for one of the Java method which looks like below:
public ApplicationUser getApplicationUser() {
ApplicationUser applicationUser = (ApplicationUser) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
return applicationUser;
}
I want to mock Spring Security Context to get the Principal, to achieve the same I mocked each level of method calls as follows:
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import static org.mockito.Mockito.when;
import static org.mockito.Mockito.mock;
import org.mockito.MockitoAnnotations;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import com.arpit.security.user.ApplicationUser;
public class BaseTest {
@Before
public void setupMock() {
MockitoAnnotations.initMocks(this);
@Test
public void mockApplicationUser() {
ApplicationUser applicationUser = mock(ApplicationUser.class);
Authentication authentication = mock(Authentication.class);
SecurityContext securityContext = mock(SecurityContext.class);
when(securityContext.getAuthentication()).thenReturn(authentication);
SecurityContextHolder.setContext(securityContext);
when(SecurityContextHolder.getContext().getAuthentication().getPrincipal()).thenReturn(applicationUser);
}
