Instructions for Testing and Measuring Code Coverage Instructions for Testing and Measuring Code Coverage

To measure [code coverage][cover], compile TESTCOV build using g++: To measure code coverage, compile TESTCOV build using g++:
mkdir -p build/testcov mkdir -p build/testcov
cd build/testcov cd build/testcov
cmake -DCMAKE_BUILD_TYPE=TESTCOV -DCMAKE_CXX_COMPILER=g++-4.8 -G Ninja ../../src cmake -DCMAKE_BUILD_TYPE=Debug -DTESTCOV=ON -DCMAKE_CXX_COMPILER=g++-4.8 -G Ninja ../../src
ninja
and run test cases: and run:
ctest ninja cov
and collect coverage data using [lcov][lcov] and [gcov][gcov]: It will build the project, run testcases, and compute code-coverage.
In the end, you have ``build/testcov/coverage`` directory containing
lcov -c -b ../../src -d . -o cov.info --no-external --gcov-tool gcov-4.8 a code-coverage report in HTML format.
and generate HTML output:
genhtml cov.info --output-directory lcov
