How can I run the IntelliJ debugger on unit tests in a Maven project?

I'm working with a multi-artifact Maven project where artifacts in the project have a few dependencies on each other. I am using IntelliJ 9. I'd like to be able to set breakpoints in my unit tests, but when I right-click on the unit tests folder for my artifact and choose "Debug 'All Tests'", I get a Class not found exception referring to a class in a separate Maven artifact.

I can run the Maven "test" goal on the parent artifact and it works fine.

Any ideas? Thanks.

Try adding this to the maven command: -DforkCount=0 i.e clean verify -DforkCount=0

I wanted to run the unit tests for a specific package.

I was able to get this to work by making a new JUnit run/debug configuration in IntelliJ. I told it to run the tests in the specific package and for "Use classpath and JDK of module", I picked the root Maven artifact.

In you run Maven from command line, you will be able to run it with debugger enabled and just attach Idea as remote debugger. That's how I usually use it.

mvn -Dmaven.surefire.debug="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 -Xnoagent -Djava.compiler=NONE" test

See http://maven.apache.org/plugins/maven-surefire-plugin/examples/debugging.html

This will allow debugger connection to port 8000 and wait for you to attach before execution.
