Kcov is a code coverage tester for compiled languages, Python and Bash. Kcov was originally a fork of Bcov, but has since evolved to support a large feature set in addition to that of Bcov.
Kcov, like Bcov, uses DWARF debugging information for compiled programs to make it possible to collect coverage information without special compiler switches.
Basic usage is straight-forward:
kcov /path/to/outdir executable [args for the executable]
/path/to/outdir will contain lcov-style HTML output generated continuously while the application runs. Kcov will also write cobertura- compatible XML output and can upload coverage data directly to http://coveralls.io for easy integration with travis-ci.
It's often useful to filter output, since e.g., /usr/include is seldom of interest. This can be done in two ways:
kcov --exclude-pattern=/usr/include --include-pattern=part/of/path,other/path \
/path/to/outdir executable
which will do a string-comparison and include everything which contains part/of/path or other/path but exclude everything that has the /usr/include string in it.
kcov --include-path=/my/src/path /path/to/outdir executable
kcov --exclude-path=/usr/include /path/to/outdir executable
Does the same thing, but with proper path lookups.
kcov coverage collection is easy to integrate with travis-ci and coveralls.io. To upload data from the travis build to coveralls, run kcov with
kcov --coveralls-id=$TRAVIS_JOB_ID /path/to/outdir executable
which in addition to regular coverage collection uploads to coveralls.
