-Here is how to use gcov to test code coverage in ldb.
-
-Step 1: build ldb with gcov enabled
-
- make clean all WITH_GCOV=1
-
-Step 3: run the test suite
- make test-tdb
-
-Step 4: produce the gcov report
- make gcov
-
-Step 5: read the summary reports
- less *.report.gcov
-
-Step 6: examine the per-file reports
- less ldb_tdb\#ldb_tdb.c.gcov
-
-You can also combine steps 2 to 4 like this:
-
- make clean all test-tdb gcov WITH_GCOV=1
-
-Note that you should not expect 100% coverage, as some error paths
-(such as memory allocation failures) are very hard to trigger. There
-are ways of working around this, but they are quite tricky (they
-involve allocation wrappers that "fork and fail on malloc").
-
-The lines to look for in the per-file reports are the ones starting
-with "#####". Those are lines that are never executed.
