Hi ,

I am using the below code in post servlet .While debugging junit code getting null in session object .Can some one please help how to pass session to junit class.

Servlet code

String sourcePath = request.getParameter("Path");

String title = request.getParameter("title");

ResourceResolver resolver = request.getResourceResolver();

Session session = resolver.adaptTo(Session.class);

String assetDetails = createAssetNode(session, sourcePath,Title);

Junit code

@Mock

private MockSlingHttpServletRequest request;

@Mock

private MockSlingHttpServletResponse response;

@Mock

private ResourceResolver resourceResolver;

@Mock

private Session session;

@BeforeEach

void setUp() throws Exception {

request = context.request();

response = context.response();

resourceResolver = context.request().getResourceResolver();

context.registerAdapter(ResourceResolver.class, Session.class, session);

context.request().setQueryString("path=/content/dam/demo/sampleimage&title=sample");

}

@2785667

void test_post() throws ServletException, IOException {

demoservlet.doPost(request,response);

assertEquals("sample",response.getOutputAsString());

}

Hi @djohn98390536 ,

Instead of registering the session object as an adapter, try a when/then to return the object

lenient().when(resourceResolver.adaptTo(Session.class)).thenReturn(session)

Hi @anupampat tried the above code not working getting below error

org.mockito.exceptions.misusing.MissingMethodInvocationException:

when() requires an argument which has to be 'a method call on a mock'.

For example:

when(mock.getArticles()).thenReturn(articles);

Also, this error might show up because:

1. you stub either of: final/private/equals()/hashCode() methods.

Those methods *cannot* be stubbed/verified.

Mocking methods declared on non-public parent classes is not supported.

How are you initializing your aemcontext ?

private final AemContext context = new AemContext(ResourceResolverType.RESOURCERESOLVER_MOCK);

Is it possible to share the complete code ?
And also can you once try using ResourceResolverType.JCR_MOCK ?

Hi @djohn98390536

Are you still getting session as a null or something else.

Above code which i shared is working fine.

can you share error if something else

@djohn98390536 Also I can see String sourcePath = request.getParameter("Path");

However in junit you are setting lowercase p

context.request().setQueryString("path=/content/dam/demo/sampleimage&title=sample");

Please correct it, else sourcePath will be null
