I read in a post from 2009 that IDEA does not support code coverage for FlexUnit. Is that still true? Is there a plugin I can get which will give me code coverage with FlexUnit?
There's nothing in common between Eclipse and IntelliJ plugin infrastructure as well as between Eclipse and IntelliJ project model, so it is not possible to convert a plugin, only write from scratch.
I'm afraid that is still true and no 3rd party plugin available. Vote/watch IDEA-54455.
Is there a way to get this eclipse plugin converted to IntelliJ?
