@kasparsd could you review, merge, and tag a new version. I need this so I can send JS coverage to Coveralls. I can obviously do it a thousand other ways like the .travis.yml, but this is a bit more elegant since it also works in the pre-commit hook locally.

@kasparsd Yes this is expecting a user defined run_tests in the .dev-lib. So you're thinking before lint_js_files, have any suggestion for what to call it? How about a before_lint and a before_tests?

@derekherman How about a generic run_checks? Then again -- all of the checks are some sort of test so your original run_tests also sounds generic enough. I'll move the generic runner above everything else and we can leave it as is.

@kasparsd sounds good!
