Blanket.js is a code coverage tool for javascript that aims to be:
- Easy to install
- Easy to use
- Easy to understand
Blanket.js can be run seamlessly or can be customized for your needs.
JavaScript code coverage compliments your existing JavaScript tests by adding code coverage statistics (which lines of your source code are covered by your tests).
Blanket works in a 3 step process:
- Loading your source files using a modified RequireJS/Require script
- Parsing the code using Esprima and node-falafel, and instrumenting the file by adding code tracking lines.
- Connecting to hooks in the test runner to output the coverage details after the tests have completed.
A Grunt plugin has been created to allow you to use Blanket like a "traditional" code coverage tool (creating instrumented copies of physical files, as opposed to live-instrumenting). The plugin runs as a standlone project and can be found here.
See the Compatiblity and Feature List including links to working examples.
git clone git@github.com:alex-seville/blanket.gitnpm install- Add your custom build details to the grunt.js file under
concat grunt buildit
A minified and unminfied copy of the source can be created (see the min task).
All development takes place on the development branch
Your pull request must pass all tests (run npm test to be sure) and respect all existing coverage thresholds
Feel free to add questions to the Issue tracker, or send them to @blanket_js.
Thanks to the many people who have contributed to the project.
And thanks also to: RequireJS, Esprima, node-falafel, Mocha, Qunit.

Loaded reverting for grunt-blanket, branch tracking reporter fixed, coverage on-the-go (displaying coverage results while a single page is being used).
Apr 28-13 - 1.1.3 YUI support added with custom adapter (and some wrapping code). CompoundJS support appears to be outside the scope of project.
