Answer 1

Step 1: Add debug to maven run configuration

You are probably using Maven Failsafe Plugin to run the tests as explained in their documentation

If that's the case you need to add -Dmaven.failsafe.debug (documentation here) to your maven configuration so it becomes

mvn -Dit.test=PredictionWorkflowTest verify -Dmaven.failsafe.debug.

When you run this maven command, the debugger will be listening at port 5005 by default

Step 2: Configure remote debugger in IntelliJ

Now in IntelliJ you need to configure a remote debugger configuration on localhost and port 5005

Remote debugger configuration for integration tests

Step 3: Debug your app

Finally, run the maven command. Just before testing it will stop and wait for the debugger to start running the tests. The following message will be displayed in the terminal

Listening for transport dt_socket at address: 5005

Then start remote debugger configured in step 2. This should allow you to debug your app on integration tests break-points.
