Traditionally code coverage products were relegated to the developer desktop environment. More recently, products like NCover (measures managed processes) have expanded that understanding to directly include white box testing and indirectly support coverage analysis for black box testing (via monitoring child processes for test applications such as QTP, TestComplete, or AutomatedQA).

The confluence of emerging development processes (Agile, BDD, etc) and the measured improvement of QA initiatives seems to demand a flexing of what was once a novelty metric. Further, many make the case that the best use of code coverage as an objective measurement of functional testing needs to include access to corollary cyclomatic complexity metrics.

By the way, NCover provides a no-strings-attached trial for anyone doing .NET development. And if you are working on anything OSS, come ask us for a complimentary license.
