Clean up your stinking pit of css.

Cesspit finds unused CSS by comparing your css to examples of your HTML. You can either provide HTML files, or integrate Cesspit with existing test suites.

You can analyze CSS using the standalone cesspit script:

$ cesspit --css test/fixtures/colors.css --html test/fixtures/red.html
test/fixtures/colors.css
	.blue

You may pass as many CSS and HTML documents as you like in. When Cesspit is done, it will print out unused selectors and the CSS files they were declared in.

Why bother generating piles of HTML documents when your tests already do it for you?

Cesspit integrates with Minitest.

# When run individually
ruby test/home_controller_test.rb --cesspit public/application.css

# With Rake:
TESTOPTS="--cesspit public/application.css" rake test

• Add support for other test frameworks.
