lcov

Summarise Code coverage information from GCOV

LCOV is an extension of GCOV, a GNU tool which provides information about what parts of a program are actually executed (i.e. "covered") while running a particular test case. The extension consists of a set of Perl scripts which build on the textual GCOV output to implement the following enhanced functionality: - HTML based output: coverage rates are additionally indicated using bar graphs and specific colors. - Support for large projects: overview pages allow quick browsing of coverage data by providing three levels of detail: directory view, file view and source code view.
