echo " How to use this script "
echo " "
echo " 0) Use Linux or Mac "
echo " - install lcov"
echo " - use the gcc compiler"
echo " "
echo " 1) Add the CMake flags: "
echo " "
echo " CMAKE_CXX_FLAGS:STRING=-g -O0 -fprofile-arcs -ftest-coverage "
echo " CMAKE_C_FLAGS:STRING= -g -O0 -fprofile-arcs -ftest-coverage "
echo " "
echo " 2) Compile VTK for Debug "
echo " "
echo " CMAKE_BUILD_TYPE Debug "
echo " "
echo " 3) From the TOP of the binary directory type the "ctest" expression that "
echo " selects the tests that you want to use to generate coverage (Ideally "
echo " this should only need to be the unit tests of the class in question). "
echo " "
echo " For example: "
echo " "
echo " ctest -R TestPLY -V -N "
echo " "
echo " This will print to the console the command line instructions needed to "
echo " run the tests (-V option), but without running the tests (-N option). "
echo " "
echo " 4) From the TOP of the binary directory type the path to this script in "
echo " the VTK source tree. Add the relative path from your location at the TOP "
echo " of the binary directory to the directory of the Module for which you want "
echo " to compute code coverage, and add the selection expression that you put "
echo " after ctest in numeral (3) above. "
echo " "
echo " More specifically, for example: "
echo " "
echo " computeCodeCoverageLocallyForOneTest.sh ./IO \ "
echo " -R TestPLY "
echo " "
echo " "
echo " This will run the selected tests in VTK and generate code coverage for "
echo " the entire toolkit, but only from the test that you have selected. The "
echo " code coverage report will be generated in HTML can be opened with your "
echo " favorite browser. The HTML report will be placed in the IO directory. "
echo " For example, in the case above: "
echo " "
echo " In Linux, you can do firefox ./IO/index.html "
echo " In Mac, you can do open ./IO/index.html "
echo " "

SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
