Creating Unit Test Cases for AEM Servlet with "system user" using Mockito

Hi experts, 

My code works to create unit test cases for AEM servlet where session is being taken through request as shown below.

Session session = req.getResourceResolver().adaptTo(Session.class);

Below test code works fine:

public final AemContext ctx = new AemContext(ResourceResolverType.JCR_MOCK);

ctx.request().setAttribute(SlingBindings.class.getName(), slingBindings);

mycustomclass.doGet(ctx.request(), ctx.response());

 

I need to know where resourceResolver is retrieved through ResourceResolverFactory and a "system" user. 

Map<String, Object> authentication = Collections.singletonMap("sling.service.subservice", (Object) systemUserName);
resourceResolver = resolverFactory.getServiceResourceResolver(authentication);

 

I get nullpointerexception at the above line. May be I need to manipulate resolverFactory object through AEMContext before calling doGet().

Can anyone please help?

 

Thanks,

Parvathy

Hi @parvathy_c ,

 

Please try below.

Map<String, Object> params = new HashMap<>();
params.put(resourceResolverFactory.SUBSERVICE, systemUserName);
ResourceResolver resourceResolver = mock(ResourceResolver.class);
ResourceResolverFactory resourceResolverFactory = mock(ResourceResolverFactory.class);
when(resourceResolverFactory.getServiceResourceResolver(params)).thenReturn(resourceResolver);

 

Thanks,

Sandeep.

Hi @parvathy_c ,

 

Please try below.

Map<String, Object> params = new HashMap<>();
params.put(resourceResolverFactory.SUBSERVICE, systemUserName);
ResourceResolver resourceResolver = mock(ResourceResolver.class);
ResourceResolverFactory resourceResolverFactory = mock(ResourceResolverFactory.class);
when(resourceResolverFactory.getServiceResourceResolver(params)).thenReturn(resourceResolver);

 

Thanks,

    Hi Sandeep, Thanks for your reply. I tried like this, as you mentioned :

    @Mock
    private ResourceResolver resolver;
    @Mock
    private ResourceResolverFactory resolverFactory;

     

    void test() throws RepositoryException, JSONException, ServletException, IOException{

    Map<String, Object> params = new HashMap<>();
    params.put(resolverFactory.SUBSERVICE, "testsystemuser");
    when(resolverFactory.getServiceResourceResolver(params)).thenReturn(resolver);
    mockContentOwnerServlet.doGet(ctx.request(), ctx.response());
    assertEquals(ctx.response().getStatus(), SlingHttpServletResponse.SC_OK);

    }

     

    But I still get nullpointer exception in the class where the below line is mentioned:

    ResourceResolver resourceResolver = resolverFactory.getServiceResourceResolver(AUTH_INFO);

     

    Any way out ?

     

    Thanks in advance!

    you can try something like this:

     

    boolean isServiceUser =true;
    User mockSystermUser = mock(User.class);
    when(mockSystermUser.isSystemUser()).thenReturn(isServiceUser);
    UserManager mockUserManager = mock(UserManager.class);
    when(mockUserManager.getAuthorizable("<<<<systemUserName>>>>")).thenReturn(mockSystermUser);

    Map<String, Object> authentication = new HashMap<>();
    authentication.put("<<<<system user.name>>>", systemUserName);
    ResourceResolver resourceResolver = context.getService(ResourceResolverFactory.class).getResourceResolver(authentication);

    doReturn(mockUserManager).when(<<update condition>>>).getUserManager(resourceResolver.adaptTo(Session.class));

      Thanks Suresh for your reply. 

      Actually UserManager is deprecated. And getAuthorizable method doesnt exist now.

      Also what do you mean by update condition? when(<<update condition>>>)

       

      Thanks,
