MockitoJUnitRunner for junit in AemContext User adapation fails

[srinivas_chann1]

Hi ,

I am using MockitoJUnitRunner for Junit .

I having the below code in java :-

In the below TestUser  class on the line

 resolver.adaptTo(User.class)  it fails and is always null how to resolve it 

import org.apache.jackrabbit.api.security.user.User;
import org.apache.sling.api.resource.ResourceResolver;

public class TestUser {

private final ResourceResolver resolver;
private final User user;

public TestUser(final ResourceResolver resolver) {
this.resolver = resolver;
this.user= resolver.adaptTo(User.class);
}
}

Sling mode class:-

@Model(adaptables = {SlingHttpServletRequest.class, Resource.class},
defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class TestClass {

@ScriptVariable
private ValueMap properties;

@ScriptVariable
private Node currentNode;

@SlingObject
private SlingHttpServletRequest request;

@Deleted Account
private Resource resource;

private String appId;

@PostConstruct
public void initModel() {
//It is used below
TestUser user = new TestUser(request.getResourceResolver());

String appId=user.getAppId();

}
}

My Test class:-

I want to test the appId value that we get from slingmodel class as

resolver.adaptTo(User.class)  fails so cannot test

@RunWith(MockitoJUnitRunner.Silent.class)
public class Testing {

private TestClass testClass;
private Resource resource;

@Rule
public final AemContext context = new AemContext(ResourceResolverType.JCR_MOCK);


protected MockSlingHttpServletRequest request;

protected MockSlingHttpServletResponse response;

@Mock
protected ResourceResolver resourceResolver;

@Mock
protected Page page;

@Mock
private TestUser testUser;


@Before
public void initialize() throws RepositoryException {
context.load().json("/resource/abc.json,
"/content/abc");
resource = context.create().
resource("/content/abc/jcr:content/test1");

page = context.create().page("/content/abc");
context.addModelsForClasses(TestClass.class);
request = context.request();
response = context.response();
context.request().setResource(resource);

slingBindings.put(SlingBindings.REQUEST, request);
slingBindings.put(SlingBindings.RESPONSE, response);
slingBindings.put(WCMBindings.CURRENT_PAGE, page);
slingBindings.put(WCMBindings.RESOURCE_PAGE, page);
slingBindings.put(WCMBindings.PAGE_PROPERTIES, resource.getValueMap());
slingBindings.put(WCMBindings.PROPERTIES, resource.getValueMap());
slingBindings.put(SlingBindings.RESOURCE, resource);
slingBindings.put(SlingBindings.SLING, context.slingScriptHelper());
slingBindings.put(WCMBindings.INHERITED_PAGE_PROPERTIES, resource.getValueMap());
slingBindings.put(SlingBindings.RESOLVER, resource.getResourceResolver());
request.setResource(resource);
request.setAttribute(SlingBindings.class.getName(), slingBindings);

TestClass = context.request().adaptTo(TestClass.class);
}

@Test
public void testMethod() {

}

}

@srinivas_chann1,

It looks like you are attempting to write tests for constructor injection, please refer to this code snippet and example for how it can be achieved, https://sourcedcode.com/blog/aem/junit-4-aem-sling-models-unit-test-constructor-injection-example.

Secondly, Why are you adapting the resolver to a UserClass.class

TestUser user = new TestUser(request.getResourceResolver()); should be 

TestUser user = request.adaptTo(TestUser.class);

Checkout the code snippet and example for Unit Test for a Sling Model, https://sourcedcode.com/blog/aem/aem-sling-models-unit-test-junit-4-with-examples.
