Comment Re:Beware coverage tools (Score 1) 169
A code coverage tool is useful to find the parts of the code not tested at all. As long as you remember that, it is a great tool (assuming it is free and easy to deploy). If you think achieving enough code coverage alone is all you need then you lose. But even in that case if you did not have the code coverage tool, you would probably just test even less.
Once sufficient code coverage is achieved, I would look at the interesting cases and if necessary just build a simple test generator to generate tests and track the achieved coverage in terms of combinations of these. Even here the code coverage is useful to have to show you someone implemented something "interesting" that you are never testing since it is undocumented..
So. Not the perfect tool but can be useful.
