Is there someway I can ask maven to pick up tests annotated with org.junit.Test ?

Update:- Added full pom.xml for reference I'm using powermockito as well to stub my static methods. Please let me know if I can add anything else as well so that it would help you debug the issues

Answer 1

From what I can see in pom.xml, there are a couple of redundant dependencies present. The reason org.junit.jupiter.api.Test gets picked is because it is a part of Junit5 and that is added as a maven-dependency with spring-boot-starter-test. Basically, your problem is you are using 2 different version of junit - 4 & 5.

In case, you want to use junit 4, please remove dependency - spring-boot-starter-test and give it a try.

Please let me know the results. Hope this will help in debugging further!
