sinon.js 测试

sinon

sinon  spies, stubs(stəb,存根), mocks

spies sinon.spy() //会调用原来的function
stubs //完全代替之前的function,不会执行原来的function
mocks  //和stubs一样，可以用来替换整个对象以改变其行为

describe('incrementStoredData', function() {
  it('should increment stored value by one', function() {
    var storeMock = sinon.mock(store);
    storeMock.expects('get').withArgs('data').returns(0);
    storeMock.expects('set').once().withArgs('data', 1);

    incrementStoredData();

    storeMock.restore();
    storeMock.verify();
  });
});

//可以处理一个对象
