how to determine junit code coverage?

Question

How can i determine what percentage of my methods are covered by jUnit tests? I am assuming there is a more sophisticated way then simply counting ...and one and two etc ...

I specifically wonder how will such counting be handled when single method is covered by 'n' tests.

please let me know and as always "thanks for reading"

I've used EclEmma very successfully to cover JUnit test runs. And its free.

Answer 3

I would suggest to go for cobertura for code coverage. It gives detailed information and can give you line by line coverage as well as branch coverage.
