Hi @ashwinikhaple,

Could you please share the details of testing related dependencies(in particular, io.wcm, junit and/or Sling context if explicitly defined) and your Java Version.

Hi @ashwinikhaple,

You are using both JUnit 4 and JUnit5 dependency.

Remove JUnit4 dependency entry and also cross check your test class file if it all uses JUnit5 related classes/API  

Junit4 dependency to be removed :

<groupId>junit</groupId>

<artifactId>junit</artifactId>

<version>4.12</version>

<scope>test</scope>

</dependency>
