Maven/Surefire not finding unit tests

Question

I tried creating a test project with maven and the unit testing worked fine. However, when trying to do the same for a j2ee project, the unit tests cannot be found by surefi

Answer 1

As Cedric said above, Surefire has some problems with TestNG and JUnit tests in the same project. I found that when running "mvn test -X", Surefire was using the testng plugin instead of junit even though the actual test was a JUnit one.

[DEBUG] Adding to surefire test classpath: C:\Users\Croydon.IVSTEL1\.m2\repository\org\apache\maven\surefire\surefire-testng\2.8\surefire-testng-2.8.jar Scope:test

I checked the dependency hierarchy and didn't find any other plugin requiring testng. Then I found the spring testng dependency.

<dependency>
  <groupId>org.apache.struts</groupId>
  <artifactId>struts2-testng-plugin</artifactId>
  <version>${org.apache.struts.version}</version>
  <scope>test</scope>
</dependency>

After disabling it,

[DEBUG] Adding to surefire test classpath: C:\Users\Croydon.IVSTEL1\.m2\repository\org\apache\maven\surefire\surefire-junit4\2.8\surefire-junit4-2.8.jar Scope: test

Surefire uses the junit plugin and the tests are detected.

Answer 2

Surefire has a few problems when you tell it to run both TestNG and JUnit tests. There is a trick to make this work, though, but I can't remember what it is right now. Try to search around, you'll probably find the answer on SO somewhere.
