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.

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,

      Yes, resourceResolverFactory is coming null mostly. But didn't quite get you. My servlet doesnt have setResourceResolverFactory method. How can i set resourceResolverFactory from testclass ?
