Hi @asarafali ,

I see there is a ClassNotFoundException and assuming you are getting this error in eclipse, try following and see if either of them resolves the issue-

1. Try using latest version of eclipse, which might help overcoming JUNIT libraries issue.

2. Try below threads-

https://stackoverflow.com/questions/4228047/java-lang-noclassdeffounderror-in-junit

https://www.baeldung.com/junit-noclassdeffounderror

Hope it helps!

Can you profile the test case structure here, as to how you are initializing the AemContext and the dependencies for unit tests. Some more information and context will be helpful.

[asarafali · Accepted solution]

It is working fine after changing the  AemContext initialization in different way .

I am also facing this issue, getting runtime error 

java.lang.RuntimeException: After setup failed (com.adobe.cq.wcm.core.components.testing.mock.ContextPlugins$1@497570fb): com/adobe/cq/wcm/core/components/internal/link/DefaultPathProcessor. I have initialized the AemContext like following

private final AemContext context = new AemContextBuilder().plugin(CORE_COMPONENTS).build();
How do we need to initialize this AemContext to overcome this runtime exception

[Gpraveen]

This runtime exception 

"java.lang.RuntimeException: After setup failed (com.adobe.cq.wcm.core.components.testing.mock.ContextPlugins$1@5baaae4c): com/adobe/cq/wcm/core/components/internal/link/DefaultPathProcessor"

is resolved once I added the following wcm-components-core dependency

<dependency>
   <groupId>com.adobe.cq</groupId>
   <artifactId>core.wcm.components.core</artifactId>
   <version>2.x.x</version>
   <scope>test</scope>
</dependency>​

and on AemContext initialization as

private final AemContext context = new AemContextBuilder(ResourceResolverType.JCR_MOCK).plugin(CORE_COMPONENTS).build();
