### Generating *.gcov files with LLVM/clang toolchain to check tests coverage
* Ensure `llvm-cov` is available
* Build and link mapnik with `--coverage` and ensure optimisation is off and profile flags is present. For example pass following options to Scons: `CUSTOM_CXXFLAGS='--coverage -g -O0' LDFLAGS='--coverage'`
* Run test(s) e.g `./test/unit/run`
* Ensure `llvm-cov` is available
* On OS X do `xcrun -f llvm-cov` to see the location of the binary
* Build and link mapnik with `--coverage` and ensure optimization is off and profile flags are present. For example pass following options to Scons: `CUSTOM_CXXFLAGS='--coverage -g -O0' LDFLAGS='--coverage'`
* Run test(s) e.g `make test`
* To generate *.gcov file(s) run `llvm-cov gcov <path-to-cpp-file>`
* *.gcov files can be viewed in text editor
