Surefire is not picking up Junit 4 tests

by

mvn -X helped me to reveal the following:

...

So it seems that the problem was coming from testng jar requiring JUnit v3.8.1. Even though Test Classpath was set to depend on JUnit 4, it was too late.

testng dependency was located in my POM:

<dependency>
  <groupId>org.testng</groupId>
  <artifactId>testng</artifactId>
  <version>5.8</version>
  <scope>test</scope>
  <classifier>jdk15</classifier>
</dependency>

Immediately after I have commented it out, tests started to execute.

Lessons learned:

  • mvn dependency:tree is not always enough, mvn -X is a friend.
  • surefire is not made for developer heaven (I have realized this while looking at project JIRA reports). This is especially true as there are no other alternatives if you use Maven.

Thanks everybody for your help. Unfortunately there is no way to split answer points between Pascal and Kaleb, but Kaleb’s advice to use mvn -X helped me to get on the right track so correct answer points go to him.
