Covered uses modern Ruby features to generate comprehensive coverage, including support for templates which are compiled into Ruby. It has the following features:

• Incremental coverage -- if you run your full test suite, and the run a subset, it will still report the correct coverage - so you can incrementally work on improving coverage.

• Integration with RSpec, Minitest, Travis & Coveralls - no need to configure anything - out of the box support for these platforms.

• It supports coverage of views -- templates compiled to Ruby code can be tracked for coverage reporting.
