What tools are out there that can perform code coverage analysis at the machine code level rather than the source code level? I'm looking for a possible solution to perform fuzz testing on software that I do not have source code access.
I think the IBM Rational test coverage tools instrument object code.
Assuming you had such a tool, but no access to the source, what exactly would code coverage mean, other than 100%?
If you didn't have 100% coverage, you'd know you hadn't exercised something. But you would have no way of knowing what.
