SPDX-License-Identifier: Apache-2.0 GraphBLAS/Tcov: statement coverage tests Requirements: the mex command must use a C compiler supporting ANSI C11. Microft Visual Studio does not support ANSI C11 so this test is not available on Windows unless you use another compiler. Since nearly all GraphBLAS tests are in *.m files, I have taken the unusual step of creating a statement coverage mechanism to use within a mexFunction. To compile GraphBLAS for statement coverage testing, and to run the tests, type this in the Command Window. grbcov If you get a linking problem on linux, add this directory to your LD_LIBRARY_PATH, so that the libgraphblas_tcov.so constructed by grbmake can be found by the mexFunctions. Statement coverage tests results will be saved in Tcov/log.txt. The lines covered by the test are marked in each file in tmp_cover/. To remove all compiled files, type this in the Unix/Linux shell: make distclean Or, delete these files manually: *.o *.obj *.mex* cover_*.c errlog*.txt grbstat.mat tmp*/* To also remove the log.txt file: make purge -------------------------------------------------------------------------------- Files in GraphBLAS/Tcov: -------------------------------------------------------------------------------- Contents.m for 'help Tcov'; list of files grbcov.m makes the tests, runs them, and lists the test coverage grbcover.m compile GraphBLAS for statement coverage testing grbcover_edit.m create a version of GraphBLAS for statement coverage tests testcov.m run all GraphBLAS tests, with statement coverage grbshow.m create a test coverage report in tmp_cover/ Makefile just for 'make clean' and 'make purge' README.txt this file GB_cover_util.c get/put the coverage log_*.txt 100% test coverage certificates tmp_cover where coverage reports are placed tmp_include for include files augmented with coverate tests tmp_source for source files augmented with coverate tests
