public class CanonicalURL extends WCMUsePojo {

public LinkCreator linkCreatorUtil;

public String path;

 

@9944223

public void activate() throws Exception {

linkCreatorUtil = getSlingScriptHelper().getService(LinkCreator.class);

path = get("path", String.class);

if (path == null) {

path = getCurrentPage().getPath();

}

}
can some one help in writing junit test case for this?
because mocking getSlingScriptHelper() is not working.

lenient().when(wcmUsePojo.getSlingScriptHelper()).thenReturn(slingScriptHelper);

lenient().when(slingScriptHelper.getService(LinkCreator.class)).thenReturn(linkCreator);

You can mock getSlingScriptHelper like below:

@Mock private Bindings bindings; @Mock private SlingScriptHelper slingScriptHelper; @BeforeEach void setUp() { Mockito.when(bindings.get("sling")).thenReturn(slingScriptHelper); Mockito.when(slingScriptHelper.getService(LinkCreator.class)) .thenReturn(linkCreator); canonicalURL.init(bindings); }

        Hi @sudarshanv1 ,

         

        Rely on AEM Context while writing unit tests. https://experienceleague.adobe.com/en/docs/experience-manager-learn/getting-started-wknd-tutorial-develop/project-archetype/unit-testing 

        @ExtendWith({ AemContextExtension.class, MockitoExtension.class }) class YourTest { private final AemContext aemContext = new AemContext(); @BeforeEach void init() { SlingBindings bindings = (SlingBindings) request.getAttribute(SlingBindings.class.getName()); CanonicalURL model = new CanonicalURL(); model.init(bindings); } }

         Best regards,
