Unit testing AEM - Mocking with Mockito

Documentation - http://mockito.github.io/mockito/docs/current/org/mockito/Mockito.html

Mockito is a Java mocking library which is very useful in unit testing but also to simplify and enhance the integration tests.


Mockito Example –

Public class MyService{

Public String readData(ResourceResolverresolver, String path) {

Resourcer= resolver.getResource(path);

returnr== null? null: r.adaptTo(String.class);

}

}

@Test

publicvoidtestReadData() {

ResourceResolverresolver= mock(ResourceResolver.class);

Resourcer src= mock(Resource.class);

when(resolver.getResource("/content/data/testdata")).thenReturn(rsrc);

when(rsrc.adaptTo(String.class)).thenReturn("OK");

MyServiceservice= newMyService();

assertEquals("OK", service.readData(resolver, "/content/data/testdata"));

}

OR  use @mock annotation and mock using initmocks().

public class TestBaseListModel {

    @Mock

    private ResourceResolver resourceResolver;

    @Mock

    private PageManager pageManager;

    @Mock

    private LinkBean linkBean;

    @Mock

    private Resource resource;

    @Before

    public void setUp() throws Exception {

        MockitoAnnotations.initMocks(this);
