ruby-on-rails - @controller 在测试 delete 时为 nil :destroy with Shoulda

Question

下面的代码：

  context "should destroy participation" do
    setup do
      @p = Factory.create :participation
      delete :destroy, :id => @p.id.to_param
    end

    should_redirect_to(:controller => 'configuration', :action => 'edit')   
  end

给我下面的错误，知道为什么吗？

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

Answer 1

您测试的非复数名称，但控制器是 ParticipationsController：

/test/functional/participation_controller_test.rb

将类名和文件名更改为：

参与控制器测试

参与控制器测试.rb

Answer 2

您必须包装should_redirect_to成一个函数，现在它在 ruby​​ 加载类时执行。

context "should destroy participation" do
  setup do
    @p = Factory.create :participation
  end

  should "redirect ...." do
    delete :destroy, :id => @p.id.to_param
    should_redirect_to(:controller => 'configuration', :action => 'edit')
  end 
end

Answer 3

控制器存在吗？在我的情况下，控制器不存在，然后 rails 没有加载控制器并向我抛出你得到的错误。
