Generate image files .gcno and data files .gcda under build/tests/CMakeFiles/.dir

Execute the following command in the build folder to generate an intermediate file for HTML:

$ lcov --capture --directory . --output-file testneuron.info --test-name testneuron

Execute the following command in the build folder to generate an HTML file in the result folder under the build folder:

$ genhtml -o result testneuron.info
