in IntelliJ IDEA with jUnit Text. Can I see how much of the project was covered in test

Yes. You need to run the test with code coverage. You can use the Run With Coverage buton . This button was a recent add (IDEA 12 I believe). Prior to it you need to turn coverage on in the run/debug configuration. In both cases, you can configure how the code coverage executes on the "Code Coverage" tab in the test's run/debug configuration.

p.s. I forgot to mention, after running you will see red and green areas on the left gutter to indicate covered (green) and not covered (red). For more information, See Help> Help Topics >IntelliJ IDEA Usage Guidelines > Code Coverage for more information.
