Spring Test Security How to mock authentication

Question

I was trying to figure out how to unit test if my the URLs of my controllers are properly secured  Just in case someone changes things around and accidentally removes security settings    My controller method looks like this    RequestMapping   api v1 resource test     Secured  ROLE USER   public  ResonseBody String test         return  test       I set up a WebTestEnvironment like so

It turned out that the SecurityContextPersistenceFilter  which is part of the Spring Security filter chain  always resets my SecurityContext  which I set calling SecurityContextHolder getContext   setAuthentication principal   or by using the  principal principal  method   This filter sets the SecurityContext in the SecurityContextHolder with a SecurityContext from a SecurityContextRepository OVERWRITING the one I set earlier  The repository is a HttpSessionSecurityContextRepository by default  The HttpSessionSecurityContextRepository inspects the given HttpRequest and tries to access the corresponding HttpSession  If it exists  it will try to read the SecurityContext from the HttpSession  If this fails  the repository generates an empty SecurityContext   Thus  my solution is to pass a HttpSession along with the request  which holds the SecurityContext   import static org springframework test web servlet request MockMvcRequestBuilders get  import static org springframework test web servlet result MockMvcResultMatchers status   import org junit Test  import org springframework mock web MockHttpSession  import org springframework security authentication UsernamePasswordAuthenticationToken  import org springframework security core context SecurityContextHolder  import org springframework security web context HttpSessionSecurityContextRepository   import eu ubicon webapp test WebappTestEnvironment   public class Test extends WebappTestEnvironment        public static class MockSecurityContext implements SecurityContext            private static final long serialVersionUID   -1386535243513362694L           private Authentication authentication           public MockSecurityContext Authentication authentication                this authentication   authentication                      Override         public Authentication getAuthentication                 return this authentication                      Override         public void setAuthentication Authentication authentication                this authentication   authentication                        Test     public void signedIn   throws Exception            UsernamePasswordAuthenticationToken principal                    this getPrincipal  test1             MockHttpSession session   new MockHttpSession            session setAttribute                  HttpSessionSecurityContextRepository SPRING SECURITY CONTEXT KEY                   new MockSecurityContext principal              super mockMvc              perform                      get   api v1 resource test                        session session                andExpect status   isOk

Pretty Late answer though  But This has worked for me   and could be useful  While Using Spring Security ans mockMvc  all you need to is use  WithMockUser annotation like others are mentioned  Spring security also provides another annotation called  WithAnonymousUser for testing unauthenticated requests  However you should be careful here  You would be expecting 401  but I got 403 Forbidden Error by default  In actual scenarios  when you are running actual service  It is redirected and you end up getting the correct 401 response code Use this annotation for anonymous requests  You may also think of ommitting the annotaions and simply keep it unauthorized  But this usually raises the correct exceptions like AuthenticationException   but you will get correct status code if it is handled correctly If you are using custom handler   I used to get 500 for this  So look for the exceptions raised in the debugger  and check if it is handled rightly and returns the correct status code

Seaching for answer I couldn t find any to be easy and flexible at the same time  then I found the Spring Security Reference and I realized there are near to perfect solutions  AOP solutions often are the greatest ones for testing  and Spring provides it with  WithMockUser   WithUserDetails and  WithSecurityContext  in this artifact   lt dependency gt       lt groupId gt org springframework security lt  groupId gt       lt artifactId gt spring-security-test lt  artifactId gt       lt version gt 4 2 2 RELEASE lt  version gt       lt scope gt test lt  scope gt   lt  dependency gt   In most cases   WithUserDetails gathers the flexibility and power I need  How  WithUserDetails works  Basically you just need to create a custom UserDetailsService with all the possible users profiles you want to test  E g  TestConfiguration public class SpringSecurityWebAuxTestConfig         Bean      Primary     public UserDetailsService userDetailsService             User basicUser   new UserImpl  quot Basic User quot    quot user company com quot    quot password quot            UserActive basicActiveUser   new UserActive basicUser  Arrays asList                  new SimpleGrantedAuthority  quot ROLE USER quot                    new SimpleGrantedAuthority  quot PERM FOO READ quot                        User managerUser   new UserImpl  quot Manager User quot    quot manager company com quot    quot password quot            UserActive managerActiveUser   new UserActive managerUser  Arrays asList                  new SimpleGrantedAuthority  quot ROLE MANAGER quot                    new SimpleGrantedAuthority  quot PERM FOO READ quot                    new SimpleGrantedAuthority  quot PERM FOO WRITE quot                    new SimpleGrantedAuthority  quot PERM FOO MANAGE quot                        return new InMemoryUserDetailsManager Arrays asList                  basicActiveUser  managerActiveUser                      Now we have our users ready  so imagine we want to test the access control to this controller function   RestController  RequestMapping  quot  foo quot   public class FooController         Secured  quot ROLE MANAGER quot        GetMapping  quot  salute quot       public String saluteYourManager  AuthenticationPrincipal User activeUser                return String format  quot Hi  s  Foo salutes you  quot   activeUser getUsername              Here we have a get mapped function to the route  foo salute and we are testing a role based security with the  Secured annotation  although you can test  PreAuthorize and  PostAuthorize as well  Let s create two tests  one to check if a valid user can see this salute response and the other to check if it s actually forbidden   RunWith SpringRunner class   SpringBootTest          webEnvironment   SpringBootTest WebEnvironment RANDOM PORT          classes   SpringSecurityWebAuxTestConfig class    AutoConfigureMockMvc public class WebApplicationSecurityTest         Autowired     private MockMvc mockMvc        Test      WithUserDetails  quot manager company com quot       public void givenManagerUser whenGetFooSalute thenOk   throws Exception               mockMvc perform MockMvcRequestBuilders get  quot  foo salute quot                    accept MediaType ALL                    andExpect status   isOk                     andExpect content   string containsString  quot manager company com quot                  Test      WithUserDetails  quot user company com quot       public void givenBasicUser whenGetFooSalute thenForbidden   throws Exception               mockMvc perform MockMvcRequestBuilders get  quot  foo salute quot                    accept MediaType ALL                    andExpect status   isForbidden              As you see we imported SpringSecurityWebAuxTestConfig to provide our users for testing  Each one used on its corresponding test case just by using a straightforward annotation  reducing code and complexity  Better use  WithMockUser for simpler Role Based Security As you see  WithUserDetails has all the flexibility you need for most of your applications  It allows you to use custom users with any GrantedAuthority  like roles or permissions  But if you are just working with roles  testing can be even easier and you could avoid constructing a custom UserDetailsService  In such cases  specify a simple combination of user  password and roles with  WithMockUser   Target  ElementType METHOD  ElementType TYPE    Retention RetentionPolicy RUNTIME   Inherited  Documented  WithSecurityContext      factory   WithMockUserSecurityContextFactory class   public  interface WithMockUser       String value   default  quot user quot        String username   default  quot  quot        String   roles   default   quot USER quot         String password   default  quot password quot      The annotation defines default values for a very basic user  As in our case the route we are testing just requires that the authenticated user be a manager  we can quit using SpringSecurityWebAuxTestConfig and do this   Test  WithMockUser roles    quot MANAGER quot   public void givenManagerUser whenGetFooSalute thenOk   throws Exception       mockMvc perform MockMvcRequestBuilders get  quot  foo salute quot                accept MediaType ALL                andExpect status   isOk                 andExpect content   string containsString  quot user quot         Notice that now instead of the user manager company com we are getting the default provided by  WithMockUser  user  yet it won t matter because what we really care about is his role  ROLE MANAGER  Conclusions As you see with annotations like  WithUserDetails and  WithMockUser we can switch between different authenticated users scenarios without building classes alienated from our architecture just for making simple tests  Its also recommended you to see how  WithSecurityContext works for even more flexibility

Options to avoid using SecurityContextHolder in tests    Option 1  use mocks - I mean mock SecurityContextHolder using some mock library - EasyMock for example Option 2  wrap call SecurityContextHolder get    in your code in some service - for example in SecurityServiceImpl with method getCurrentPrincipal that implements SecurityService interface and then in your tests you can simply create mock implementation of this interface that returns the desired principal without access to SecurityContextHolder

Since Spring 4 0   the best solution is to annotate the test method with  WithMockUser   Test  WithMockUser username    user1   password    pwd   roles    USER   public void mytest1   throws Exception       mockMvc perform get   someApi             andExpect status   isOk         Remember to add the following dependency to your project   org springframework security spring-security-test 4 2 3 RELEASE
