Code coverage tools in Java [closed]

Are there any such code coverage tools in Java that give the different paths in the program. Basically the idea is to ensure that all loops and nested loops are covered during execution. That is to be able to ascertain if all the loops in a code base have been executed at least through one iteration.

No, it is not. He asked for path coverage tools. See en.wikipedia.org/wiki/Code_coverage for definitions. Most of the answers provided to this question don't answer the question as posed. - Ira Baxter

Cobertura, EMMA and even Clover only do branch/decision coverage (in addition to line/statement coverage, of course). Clover also provides method coverage (which simply measures if a method was entered at all during execution).

For path coverage (plus line/statement coverage), try JMockit Coverage.

A sample report can be found here.

Actually, as of now this is only an initial version of the new path coverage support, which I still need to improve.

Cobertura is another popularly used tool.

I'd go with JaCoCo It's an open source tool (replacement for EMMA) distributed under Eclipse's public license.
