css-coverage

CSS Coverage!

Generates coverage information of your CSS files and creates reports using the optional source maps.

How is this different from other CSS coverage tools?

  • gives coverage information on your source files (SASS/LESS/Stylus/etc), not just the compiled CSS file
  • provides a command line script to run against individual test files

What can I do with css-coverage?

You can use the command line version to:

  • test a CSS and HTML file one at a time
  • use css-coverage as part of a build (like in GruntJS)
  • generate a LCOV Report for use in services like Coveralls or HTML reports using lcov

Can I make Reports?

You can also generate LCOV Files for Coveralls or just HTML reports:

# Run CSS Coverage and generate a LCOV report (with verbose output)
css-coverage --css ./test/test.css --html ./test/test.html --lcov ./css.lcov

# Optionally Generate an HTML report
genhtml ./css.lcov --output-directory ./coverage
