In IntelliJ, how do i debug a maven test goal?

Using intellij and maven pom files, how do i debug tests run inside the maven test goal?

When i run them directly in the code, it complains something about profiles missing, which i've ticked inside intellij's Maven Projects.


What about a right click on your goal and "Debug [your goal]" (in your case the test goal)?

In IDEA, run your test in debug mode "mvn -DforkMode=never test"

Updated: Open your run/debug configuration, in "Runner" tab, add -DforkMode=never

(Noted by @mikeapr4: newer versions of the surefire plugin (2.14+) use mvn -DforkCount=0 test)

I execute tests with the following options:

mvn -Dmaven.surefire.debug="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=6666 -Xnoagent -Djava.compiler=NONE" test

... and then connect to Maven with remote debugger.

-DforkMode=never doesn't work anymore, it is now deprecated in SureFire.

Use -DforkCount=0 instead when using surefire plugin 2.14+.

The question has been answered. But just to share my own experience. The selected answer did not solve my problem. My code has multiple modules.

foolshat's reply did bring valuable insight to my problem.

I have two solutions, 1. Using your IDEA, by adding a VM option -DforkMode=never; Must run it with debug mode. 2. Set up a remote debugging, specifying the socket and in this case forkMode is not necessary.

It is just a summary for what I have been through.

The solution from Colin Hebert is not working to me neither. But fortunelly I found an easy way to debug the test by doing right click on the green triangle appears next to the test method:

I hope thats helps you!
