ruby-on-rails - Mocha 对关联构建调用失败的期望

Question

我有这个例子:

# GET New
context "on get to new" do
  it "should assign cardset" do
    @profile.cardsets.expects(:build).once.returns(Factory.stub(:cardset))
    get :new
    assigns[:cardset].should_not be_nil
  end
end

要测试此方法:

# GET /cardsets/new
def new
  @cardset = current_user.cardsets.build
end

我试图强制该关联是从 current_user 建立的。确保用户只创建属于自己的东西。我正在使用非常相似的期望来确保他们正在调用 find来自 current_user对象，它可以找到，但是在运行上面的示例时，我得到:

Mocha::ExpectationError in 'CardsetsController for a logged in user on get to new should assign cardset'
not all expectations were satisfied
unsatisfied expectations:
- expected exactly once, not yet invoked: [#<Cardset:0x102eaa8c8>, #<Cardset:0x102e12438>].build(any_parameters)
satisfied expectations:
- allowed any number of times, not yet invoked: ApplicationController.require_user(any_parameters)
- allowed any number of times, already invoked twice: #<CardsetsController:0x1030849c8>.current_user(any_parameters)

在对从 current_user 返回它的函数 stub 后，您将期望添加到 @profile。可能你需要做的是:

# GET New
context "on get to new" do
  it "should assign cardset" do
    @profile.cardsets.expects(:build).once.returns(Factory.stub(:cardset))
    controller.stubs(:current_user).returns(@profile)
    get :new
    assigns[:cardset].should_not be_nil
  end
end
