AEM junits using aem mocks

[girishb83316758]

Hi All

I'm using aem mocks in my project

Aem mocks version: 5.0.0

Aem mock core version:5.0.0

And i have written a junit test class like below

Private AemContext aemContext = new AemContext

@Before

Public void setup() {

Assest asset = aemContext.create().asset("/content/dam/simple.jpg", 240, 280, "image/jpeg")

}

When I execute the test class.

I get the error

Java.lang.RuntimeExcsption: No asset manager

at io.wcm.tetsing.mock.builder.contentBuilder.asset()

Can some one please help tell me what is the issue??

Hi @girishb83316758 

As the error says, you need to mock the asset manager like this:

@Mock
	private AssetManager assetManager;

Hope this helps!

Thanks,

Check this sample code for creating asset and testing it.

You seem to be using the generic AemContext() instead use the `AemContext(ResourceResolverType.JCR_MOCK)`, which sets the ResourceResolver and be able to adaptTo AssetManager object, which is then used when creating the Asset.

I have an example here that you can refer to

@ExtendWith(AemContextExtension.class)
public class AssetTest {
    AemContext aemContext = new AemContext(ResourceResolverType.JCR_MOCK);
    @BeforeEach
    void setup() {
        asset = aemContext.create().asset("/content/dam/simple.jpg", 240, 280, "image/jpeg");
    }
    private Asset asset;

    @Test
    void testAssetPath() {
        assertEquals(asset.getPath(), "/content/dam/simple.jpg");
    }
}

Can you help with the dependencies you have added??

[Lokesh_Vajrala]

The two main dependencies you needed are 

<dependency>
     <groupId>io.wcm</groupId>
     <artifactId>io.wcm.testing.aem-mock.junit5</artifactId>
</dependency>
<dependency>
    <groupId>junit-addons</groupId>
    <artifactId>junit-addons</artifactId>
</dependency>

You may need other dependencies based on your project setup.

What is the uber-jar version you are using?

[Lokesh_Vajrala]

I'm using a cloud service setup with sdk api, not uber-jar.

For some reason I don't know why AemContext class is not working with below dependency in AEM6.5.12

<dependency>

<groupId>io.wcm</groupId>

<artifactId>io.wcm.testing.aem-mock.junit5</artifactId>

<scope>test</test>

</dependency>

I added junit4 version and I was able to use AemContext class and mock assets in Junits

Below dependency worked for me

<dependency>

<groupId>io.wcm</groupId>

<artifactId>io.wcm.testing.aem-mock.junit4</artifactId>

<version>4.1.8</version>

</dependency>
