Istanbul and JSCoverage-style instrumentation for CoffeeScript files.

CoffeeCoverage

Coverage Status

Instruments CoffeeScript files for code coverage. Compiles .coffee files to .js files, and adds JSCoverage or Istanbul style instrumentation for the original coffee script source.

NPM

Features

Quick Start

Assuming you have a folder named "test" full of mocha tests, which directly loads your .coffee files, then from your project's folder, run:

npm install --save-dev @danielx/coffeecoverage
npm install --save-dev istanbul
mocha --recursive --compilers coffee:coffeescript/register --require @danielx/coffeecoverage/register-istanbul test

./node_modules/.bin/istanbul report

You should now have an Istanbul coverage report in ./coverage/lcov-report/index.html.

If this doesn't quite do what you're after, check out our tutorials below:

What it Does

CoffeeCoverage is a tool for determining the coverage of your unit tests. It does this by instrumenting .coffee files to see how often each line, branch, or function is executed. CoffeeCoverage is capable of producing both Istanbul and JSCoverage style instrumentation.
