Mocha vs. suite.js

mocha.js

// https://github.com/visionmedia/mocha
var assert = require("assert");

describe('Array', function(){
  describe('#indexOf()', function(){
    it('should return -1 when the value is not present', function(){
      assert.equal(-1, [1,2,3].indexOf(5));
      assert.equal(-1, [1,2,3].indexOf(0));
    })
  })
})

suite.js

// https://github.com/bebraw/suite.js
var suite = require('./suite');

suite([1, 2, 3].indexOf, [
    5, -1,
    0, -1
]);
