Another not so obvious case is when code coverage is needed on more than one project. The naive solution would be to select multiple projects and run all unit tests in them at once. As it turns out, unit tests may fail if the classpath changes and IntelliJ has exactly one classpath entry per run configuration. In this case, running unit tests on projects sequentially is actually sufficient. That's because at the end of each run IntelliJ (2017.2.5 Community Edition) asks if the collected coverage should replace or should be added to previously collected coverage stats.
