#3819: Add test coverage of C files
-------------------------+-------------------------
Reporter: pmav99 | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone:
Component: Compiling | Version: svn-trunk
Keywords: | CPU: Unspecified
Platform: Unspecified |
-------------------------+-------------------------
Disclaimer: I've only tested with gcc.
Using the info from these links I managed to get test coverage for the C
codebase:
- https://stackoverflow.com/questions/16682606/how-to-resovle-gcov-init-
undefined-reference-issue-when-link
- https://stackoverflow.com/questions/39086957/test-coverage-from-swig-
compiled-c-python-code
1. install [https://gcc.gnu.org/onlinedocs/gcc/Gcov.html gcov]
2. Compile with these options:
{{{
export CFLAGS='-O0 -fPIC -march=native -std=gnu99 -fprofile-arcs -ftest-
coverage -g'
export LDFLAGS='-s -lgcov --coverage'
}}}
3. Run tests
4. Generate test coverage reports (there may be warning/errors):
{{{
mkdir -p coverage
gcovr -r . --filter="" --html --html-details -o coverage/coverage.html
}}}
5. Inspect coverage:
{{{
firefox coverage/coverage.html
}}}
If possible, this should be added to fatra and once #3771 is resolved, on
travis too.
I guess that it would also make sense to add a configure option like e.g.
[https://www.gaia-gis.it/fossil/libspatialite/artifact/f5c88dedc9888f65
libspatialite]:
{{{
#-----------------------------------------------------------------------
# --enable-gcov
#
# Check whether --enable-gcov was given.
if test "${enable_gcov+set}" = set; then :
enableval=$enable_gcov;
fi
if test "x$enable_gcov" = "xyes"; then
CFLAGS=$CFLAGS" -fprofile-arcs -ftest-coverage -g"
GCOV_FLAGS="-lgcov"
fi
#-----------------------------------------------------------------------
}}}
