Code coverage tool for Bash.
Bashcov is a code coverage analysis tool for Bash.
In most cases, you'll want overall coverage results for your project from shUnit2, Bats, bash_unit, assert.sh, bashaspec, etc. Bashcov automatically takes care of this by caching and merging results when generating reports, so your report includes coverage across your test suites and thereby gives you a better picture of blank spots.
It uses the SimpleCov coverage library to generate HTML reports. SimpleCov gets installed automatically when you install Bashcov.
