Instructions for Testing and Measuring Code Coverage
|
||
|
|
====================================================
|
||
|
|
|
||
|
|
To measure [code coverage][cover], compile TESTCOV build using g++:
|
||
|
|
|
||
|
|
mkdir -p build/testcov
|
||
|
|
cd build/testcov
|
||
|
|
cmake -DCMAKE_BUILD_TYPE=TESTCOV -DCMAKE_CXX_COMPILER=g++-4.8 -G Ninja ../../src
|
||
|
|
ninja
|
||
|
|
|
||
|
|
and run test cases:
|
||
|
|
|
||
|
|
ctest
|
||
|
|
|
||
|
|
and collect coverage data using [lcov][lcov] and [gcov][gcov]:
|
||
|
|
|
||
|
|
lcov -c -b ../../src -d . -o cov.info --no-external --gcov-tool gcov-4.8
|
||
|
|
|
||
|
|
and generate HTML output:
|
||
|
|
|
||
|
|
genhtml cov.info --output-directory lcov
|
||
|
|
|
||
|
|
Note: make sure that the version of ``gcov`` matches with the one of
|
||
|
|
``g++``. Also try to use the latest ``lcov`` if you have a problem
|
||
|
|
with the existing one.
