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.

CukeModeler facilitates modeling a test suite that is written in Gherkin (e.g. Cucumber, SpecFlow, Lettuce, etc.). It does this by providing an abstraction layer on top of the Abstract Syntax Tree (AST) that the cucumber-gherkin generates when parsing features, as well as providing models for feature files and directories in order to be able to have a fully traversable model tree of a test suite's structure. These models can then be analyzed or manipulated more easily than the underlying AST layer.
