How do you get code coverage to work?

"View -> show code coverage information" is probably what you are looking for.

Thanks! ... :-D

Have you got a key for the colours used in the gutter?

And can you change them?

No, haven't had time for this yet, sorry:(

No problem. Easy enough to work out ... but always nice just for completeness ... :)

I've done all that, but, still, no coloring shows up. Any ideas where to look next?

Well, you need to provide a step-by-step description of what you we doing, and what IDEA was telling you at each step.

Have you included the emma.jar file as part of your project?

• I included emma.jar in my project

• I enabled code coverage in my JUnit test configuration

• I run my tests.

• I select "show code coverage info"

• The resulting window shows one choice, from the just-completed test run

• I select it.

After that, no coloring, no percentages in the packages view. No visible sign of any coverage information that I can see.

Is there a *.es file stored in $IDEA_HOME/system/coverage directory?

No, there are no files at all in $IDEA_HOME/system/coverage.

OK, then I suppose there was a message in run console saying something like "No coverage gathered"?

No, there is no such message. Here's what's on the console:

Does it help if you change the name of the configuration from ]]> to something meaningful?

Does it help if you change the name of the
configuration from <default> to something meaningful?

Where do I change that? The name of my test configuration is 'unittest', so I'm not sure where the is coming from. The ]]> is almost certainly the problem, since that's not a legal filename.

OK, then I'll most probably be able to fix it by next EAP. It's already 11 PM, and it's football time here in Europe:)

>It's already 11 PM, and it's football time here

in Europe:)

I hear that!

OK, I've fixed the problem. Till next EAP you can play with coverage support running tests for non-default packages.

Also you may try setting up the filters to instrument your classes only. This way you will get a much better tests startup performance.

Ah, after supplying a non-default package, the coverage information shows up as expected.
