Because you want to know which parts of your C++ code are actually being tested – not just assumed to be. Currently I've been using GCOVR and GCC coverage flags to produce detailed code coverage reports when using a C++ Typically, the problem is either that gcovr is confused about path names and thinks your source code isn't part of your project, or it doesn't manage to invoke gcov properly. This The EXECUTABLE option should define how to run something on your code and generate coverage data. Want to add code coverage and integrate that to the target ExperimentalCoverage. I was wondering if there is some kind of a coverage tool for cmake itself, which helps to identify dead Is it possible to get code coverage done by tests using google test (GTest) framework?
