This doesn't help you with your Javascript problem but Cobertura4J2ME does work quite well now on mobile java code.

Ah I see. It precludes you from determining the answer statically, is all I meant (i.e. you can't just have a tool that looks at the code and figures it out). It can of course do it in the way you describe.

How does JavaScript having closures preclude it from code coverage analysis? Ruby has closures and it has some decent code coverage tools.

AFAIK most CC tools inject traces into the code and then run the tests, so computing what gets run and what does not.

Since JavaScript has closures, I think it's impossible to compute (though may be wrong). You could do it dynamically (i.e. run the scripts for a long time and see what happens) but it's not guaranteed to be correct. You could also get a conservative approximation using standard algorithms.

I'm hearing some rumblings too that a similar problem exists with J2ME code coverage tools. Apparently, there is an extension to Cobertura but it does not work correctly (yet).
