mocha　入门 (mocha quick start)

refer to:  http://mochajs.org/

mocha很简单。如果你已经有了rspec, unit test等经验的话

$ npm install -g mocha

$ mkdir test

$ vim test/test.js

var assert = require("assert")
describe('lala ', function(){
  describe('#ihaha ()', 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));
    })
  })
})

s mocha  或者 $mocha test

  Array
    #indexOf()
      ✓ should return -1 when the value is not present 


  1 passing (7ms)

值得一提的是，mocha 一样有before after, 

describe('hooks', function() {
  before(function() {
    // runs before all tests in this block
  })
  after(function(){
    // runs after all tests in this block
  })
  beforeEach(function(){
    // runs before each test in this block
  })
  afterEach(function(){
    // runs after each test in this block
  })
  // test cases
})

更逗的是，它的 结果报告做的很有意思。 大家可以自己看一下。
