Do you mean a multi-module maven project? – Coup

Yes, I mean a pom with multiple sub-poms. – Doodlebug

These days this is only in Ultimate – Washin

Answer 1

Create a Run Configuration that will look for tests in the whole project. Make sure that you choose All in package and In whole project in the configurations dialog:

Make sure that you choose the <default> package in the Choose Package dialog.

Now you can select to run this configuration using Run 'All in project' with Coverage:

The result will be presented in a separate coverate window:

And you will also see the result in the Project View window for a fast overview:

Answer 2

Right click on the parent module (root pom), and select Run 'All Tests' with Coverage.

There is no such option when I right click on the root module. May be the problem is that this folder is not marked as source/test. – Doodlebug

Works for me. Right-click the root directory where your pom.xml and src sit in. – Unperforated

Answer 3

There is a 'Coverage' plugin, which may not be enabled by default.

Find it at File->Settings->Plugins.

This will enable the 'Run with Coverage' buttons and menu items.

Answer 4

To expand on ceilfors answer since it has slightly changed.

Right click on the test module -> More Run/Debug -> Run 'Tests in ...' with Coverage

This is with IntelliJ IDEA 2022.3.2 (Ultimate Edition)

Also the doc shows another way to do it: https://www.jetbrains.com/help/idea/running-test-with-coverage.html
