ruby-on-rails – 加速rspec控制器测试：使用之前都失败？

我有一个简单的控制器测试,包含a.o.以下代码：

context "POST :create" do
  before (:each) do
    post :create,:user_id => @user.id,:account => { .. some data ... }
  end
  it { response.status.should == 201 }
  it { response.location.should be_present }
end

现在我想到了一个非常简单的方法来加速这个测试,并且使用before(：all)而不是before(：each).在这种情况下,该职位只会做一次.

所以我写道：

context "POST :create" do
  before (:all) do
    post :create,:account => { .. some data ... }
  end
  it { response.status.should == 201 }
  it { response.location.should be_present }
end

但是,我收到以下错误：

RuntimeError:
   @routes is nil: make sure you set it in your test's setup method.

这是设计吗？有办法规避吗？

解决方法

我在rspec邮件列表中提出了这个问题,并从@dchelimsky自己得到以下答复：

Yes. rspec-rails wraps the rails’ testing framework which doesn’t have a before(:all) concept in it,so all the data is reset before each example. Even if we wanted to support this in rspec-rails (which I don’t) it would require changes to rails first.

所以在以前(:(全部))中执行控制器调用是不可能的,它只能用于设置数据库或实例变量.
