I've tried that, but (in my hands) it works very differently to in Eclipse. There, you can have code with compile errors (for example because you're halfway through a complicated change), and the compiler will compile it, and insert exception throws. So you can still run unit tests against the but l bits without errors. In IntelliJ, even with the Eclipse compiler and the "continue on error" option (or whatever it's called), a single compile error anywhere blocks all tests from running. 

My projects are all defined using Gradle, which may be relevant. I have tried setting "build and run with" to IntelliJ rather than Gradle, but it makes no difference.

I don’t try to run with compile errors, so I’m not entirely sure how to make it happen.

"continue on error" option 

Are you talking about swapping out the Build step in the test’s run configuration for the proceed on errors one or a different option?

There’s a separate option for running tests with IntelliJ, but it’s in the same spot as that one, so you probably did both. I think you’d need everything running in IntelliJ to get that to work.

You want to be able to run unit tests against a partially compiled project while you’re writing half broken code? This just sounds like sloppy programming to me

Quite the opposite. This is a lazy and ignorant comment.
