You can test your AEM Java code by using the Test class that is generated for you when you build an Adobe Maven 11+ Archetype project.
For example, assume you create a project named AEM633. Once you build this project, you will have a class named TestHelloWorldModel located in this package:
com.foo.core.models (under src\test\java)
All of the POM dependencies are setup for you. Create a simple interface in the Core package named Foo.
package com.foo.core;
public interface Foo {
public String getName();
}
Then create an implementation class that uses a @Component annotation in the same package.
package com.foo.core;
import org.osgi.service.component.annotations.Component;
@Component
public class FooImpl implements Foo{
public String getName()
{
return "Scott" ;
}
}
This is about the most basic AEM class that you can build. It has one method that returns a static value for the getName method. Now the question is how can we test this method?
The answer is to use the TestHelloWorldModel class that already exists. You can create a Foo object and then test the getName method. See the bold code below.
package com.foo.core.models;
import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.assertTrue;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;
import java.util.UUID;
import junitx.util.PrivateAccessor;
import org.apache.sling.settings.SlingSettingsService;
import org.junit.Before;
import org.junit.Test;
import com.foo.core.Foo;
import com.foo.core.FooImpl;
/**
* Simple JUnit test verifying the HelloWorldModel
*/
public class TestHelloWorldModel {
//@Inject
private HelloWorldModel hello;
private Foo myFoo;
private String slingId;
@Before
public void setup() throws Exception {
SlingSettingsService settings = mock(SlingSettingsService.class);
slingId = UUID.randomUUID().toString();
when(settings.getSlingId()).thenReturn(slingId);
hello = new HelloWorldModel();
PrivateAccessor.setField(hello, "settings", settings);
hello.init();
myFoo = new FooImpl();
}
@Test
public void testGetMessage() throws Exception {
// some very basic junit tests
String msg = hello.getMessage();
assertNotNull(msg);
assertTrue(msg.length() > 0);
}
@Test
public void testFooMessage() throws Exception {
//custom service
String msgFoo = myFoo.getName() ;
assertNotNull(msgFoo);
assertTrue(msgFoo.length() > 0);
}
}
When you build the Maven project (for example, mvn clean install), you can see the Test results that are written to this file:
C:\AdobeCQ\AEM633\core\target\surefire-reports\com.foo.core.models.TestHelloWorldModel.txt
