hi guys i need help from you, i created chillist servlet for reading properties from /content it returns a JSONArray of the node's child node paths and properties.
so plz help for unit testing. i need unit testing script for this code, this my code
package com.aem.community.core.servlets;
import java.io.IOException;
import javax.jcr.Node;
import javax.jcr.NodeIterator;
import javax.jcr.RepositoryException;
import javax.servlet.ServletException;
import org.apache.felix.scr.annotations.Service;
import org.apache.felix.scr.annotations.sling.SlingServlet;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.apache.sling.commons.json.JSONArray;
import org.apache.sling.commons.json.JSONException;
import org.apache.sling.commons.json.JSONObject;
import org.apache.sling.commons.json.jcr.JsonJcrNode;
import org.osgi.service.component.annotations.Component;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Component(enabled = true, immediate = true)
@Service(ChildList.class)
@SlingServlet(resourceTypes="sling/servlet/default",selectors="childlist",methods="GET",extensions="json",metatype=true)
public class ChildList extends SlingAllMethodsServlet {
protected final Logger loger = LoggerFactory.getLogger(ChildList.class);
private static final long serialVersionUID = 9176255033916949528L;
private JSONArray array;
@Override
public void doGet(final SlingHttpServletRequest request, final SlingHttpServletResponse response)
throws ServletException, IOException {
try{
ResourceResolver resolver = request.getResourceResolver();
Resource resource = resolver.getResource(request.getRequestPathInfo().getResourcePath());
Node node = null;
if (resource != null) {
node = resource.adaptTo(Node.class);
}
if (node == null){
throw new RepositoryException();
}
NodeIterator it = node.getNodes();
array = new JSONArray();
while (it.hasNext()) {
Node child = it.nextNode();
if (loger.isDebugEnabled()){
loger.debug("resource......."+child.getPath());
}
JSONObject obj = new JsonJcrNode(child);
array.put(obj);
response.setContentType("application/json");
response.getOutputStream().print(array.toString());
}
}
catch(RepositoryException e) {
throw new ServletException("404 HTTP ERROR Page Not Found", e);
}
catch(JSONException e)
{
loger.error("Could not formulate JSON response");
throw new ServletException("Error", e);
}
}
}
Solved! Go to Solution.
Today I rewrote unittests for the whole day ... so while I just was on it, I wrote them for this question, too.
You can find the complete code at https://github.com/joerghoh/cqdump/tree/master/unittests
Clone it and then run it (the usual "mvn clean install").
The relevant bits and pieces:
I used the AEM Mocks from wcm.io, which work pretty good for usecases like yours.
HTH,
Jörg

Have you looked at the default test package when you generate a maven archetype 12/13 project.
You can use JUNIT code to test application logic here. For example - here a model class. WHen you build the maven project - you can see the Tests run and the results.

hi bro..i written like this
@RunWith(MockitoJUnitRunner.class)
public class ChildListTest {
@InjectMocks
private ChildList childlist;
@Mock
private SlingHttpServletRequest request;
@Mock
private SlingHttpServletResponse response;
@Mock
Resource resource;
Logger LOGGER;
@Mock
Node nodes;
@Mock
private ResourceResolverFactory resourceResolverFactory;
@Rule
public final AemContext context = new AemContext();
@Before
public void setup() {
//childlist=new ChildList();
MockitoAnnotations.initMocks(this);
}
@Test
public void testDoGet() throws ServletException, IOException, RepositoryException, JSONException
{
/*//childlist.doGet(context.request(),context.response());
resource = context.resourceResolver().getResource("/content");
ResourceResolver resolver = request.getResourceResolver();
resource = resolver.getResource(request.getRequestPathInfo().getResourcePath());
nodes=resource.adaptTo(Node.class);
NodeIterator it=nodes.getNodes();
}

Try creating another class in the test package. Then use Java APIs to invoke the Servlet and use assertTrue on the value the servlet returns.
Also - you do not need @Component and @Servlet when using @SlingServlet.

Invoke the Servlet using JAVA HTTP APIS -- something like:
@Test
public void testinvokeServlet() throws Exception {
// some very basic junit tests
<PUT IN JAVA HTTP CODE TO CALL SERVLET>
assertTrue(msg.length() > 0);
}
ie --
//Create an HTTPClient object
HttpClient client =
new
HttpClient();
HttpMethod method =
new
GetMethod(
"http://localhost:4502/bin/mySearchServlet"
);

with that @Slingservlet ex:http://localhost:4502/content.childlist.json whenever hit this url we can get jsonarray for node properties.,
actaul requirement ->This web service is mounted to the selector .childlist.json. Given any node path, it returns a JSONArray of the node's child node paths and properties.
so that's why i created servlet with selector.extension

You should still be able to invoke it using Java HTTP API and use an asset call to test return value.

I'd look into using Sling Mocks or other mocking frameworks to simulate complex objects that are impractical to incorporate into the unit test. The goal should be to isolate and test behavior of the code within the servlet, not necessarily the servlet itself. Check out Sling Mocks: Apache Sling :: Sling Mocks . Mocks can be used to unit test code prior to deployment.
If you do want to some more real-world testing (on say a stage/QA environment) you can also look into server side integration testing as well: https://sling.apache.org/documentation/development/sling-testing-tools.htm (Maven achetype 13 has an example of server-side integration test). These will be executed after code is deployed to the AEM environment.

i did't get it..https://github.com/joerghoh/cqdump/blob/master/unittests/core/src/main/java/de/joerghoh/cqdump/core/... why it is using ChildListOptimized.java..,
private JSONObject convertResourceToJSON (Resource resource) throws JSONException {
JSONObject obj = new JSONObject();
obj.put("jcr:path", resource.getPath());
ValueMap vm = resource.adaptTo(ValueMap.class);
vm.forEach((key,value) -> {
vm.put(key, value);
});
return obj;
}
* in that what is key and value it's getting error

You can safely ignore the "optimized version" for the moment; I just wanted to demonstrate that you can easily achieve the (more or less) same functionality without using the JCR API.

Check the pom.xml as well. Make sure that you include the "junit" dependencies.
