A bridge for using Claire in Mocha

Claire for Mocha

Claire for Mocha is a library that makes it easier to use the [Claire][] property-based testing library in Mocha.

Just use Claire for Mocha's forAll to define your properties:

global <<< require 'claire-mocha'
global <<< (require 'claire').data
{ for-all } = require 'claire'
describe 'Lists' ->
  o 'Concatenation' -> do
                       for-all (List Int), (List Int)
                       .satisfy (xs, ys) -> (xs.length + ys.length) is (xs ++ ys).length

And run Mocha as you normally would:

$ mocha
    ✓ - Concatenation should yield lists with the same size    
$ npm install claire-mocha

MIT/X11. ie.: Do whatever you want.
