Testing AEM Servlets

[tim-schwalbe-NZ]

Hello its me again,

I want to test my Servlet but after the test started I got an error message:

Error:(60, 28) java: cannot access org.junit.rules.TestRule

  class file for org.junit.rules.TestRule not found

The test does not start.

I don't have any Idea how to solve this, I am also not very experienced with test for AEM. It would be nice if you can tell me something.

@RunWith(MockitoJUnitRunner.class)

public class RssFeedServletTest {

   @InjectMocks
   private RssFeedServlet rssFeedServlet;
   @Mock
   private SlingHttpServletRequest request;
   @Mock
   private SlingHttpServletResponse response;
   @Mock
   private Page page;
   @Mock
   Resource resource;
   Logger LOGGER;

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

   @Before
   public void setUp() throws Exception {

   rssFeedServlet = new RssFeedServlet();
   MockitoAnnotations.initMocks(this);
   mockStatic(LoggerFactory.class);
   LOGGER = mock(Logger.class);
   PowerMockito.when(LoggerFactory.getLogger(any(Class.class))).thenReturn(LOGGER);
   when(request.getServerName()).thenReturn("https://www.test.com");

   Page page = context.pageManager().create("/content/test/de/ueber-uns/presse/press-releases/2017/release1", "release1",
   "/apps/test/foundation/templates/basepage", "release-title1");

   when(resource.getParent().adaptTo(Page.class)).thenReturn(page);

   when(request.getResource()).thenReturn(resource);

   }

   @Test
   public void testDoGetForJson() throws IOException {

   context.requestPathInfo().setSelectorString("rss");
   context.requestPathInfo().setExtension("xml");
   context.currentPage("/content/test/de/ueber-uns/presse/press-releases");

   rssFeedServlet.doGet(context.request(), context.response());


   }

}

Here is a GEMS Session where they cover JUNIT Testing - From Unit Testing to Integration Test of an AEM Application

[Jörg_Hoh]

I don't find the @TestRule annotation in the code you pasted. I would assume that the error message references a different file. Can you paste this relevant file?

[tim-schwalbe-NZ]

It is there :  

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

[tim-schwalbe-NZ]

Here is another example with the same error:

java: cannot access org.junit.rules.TestRule class file for org.junit.rules.TestRule not found

import com.day.cq.wcm.api.Page;
  import io.wcm.testing.mock.aem.junit.AemContext;
  import org.apache.sling.api.resource.Resource;
  import org.junit.Before;
  import org.junit.Rule;
  import org.junit.Test;

public class ExampleTest {

  @Rule
  public final AemContext context = new AemContext();

  @Before
  public void setUp() throws Exception {

  }

  @Test
  public void testSomething() {

  Resource resource = context.resourceResolver().getResource("/content/sample/en");
   Page page = resource.adaptTo(Page.class);
   // further testing
  }

}

Okay now it was able to solve the issue.

I just need to add the following lib and deleted the same libs without version number. Can anyone explain whats about the libs without version? Where does the version come from?

<dependency>
  <groupId>io.wcm</groupId>
  <artifactId>io.wcm.testing.aem-mock</artifactId>
  <version>2.2.8</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.12</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>junit-addons</groupId>
  <artifactId>junit-addons</artifactId>
  <version>1.4</version>
  <scope>test</scope>
</dependency>

Obviously you inherited a version number from some parent pom (just let you display the effective POM).
