ruby-on-rails - Rspec:测试救援

Question

尝试测试我的函数是否能正确地从异常中解救出来，更改参数(文件名)，然后再试一次。我可以获得接收第一次尝试的功能，但无法接收第二次尝试。

Controller

begin
  @video = get_video(video_id)
rescue
  matches = video_id.match(/(.*)[-](\d+)+x(\d+)_(\d+)/)
  swapped_dash = (matches && matches.size == 5) ? "#{matches[1]}_#{matches[2]}x#{matches[3]}_#{matches[4]}" : nil
  @video = swapped_dash.nil? ? false : get_video(swapped_dash) rescue false
end

规范

it "attempts to find a video with an underscore if the original filename is not found" do
  controller.stub(:get_video).and_return(Exception)
  controller.should_receive(:get_video).with("MyString-480x272_8").once.ordered
  controller.should_receive(:get_video).with("MyString_480x272_8").once.ordered
  get 'player_only', :video_id => "MyString-480x272_8"
end

错误:

(#<WatchController:0x00000105d03c60>).get_video("MyString_480x272_8")
    expected: 1 time
    received: 0 times

尝试了一些东西，但没有任何效果。有什么想法吗？

提前致谢!

您应该使用 and_raise 而不是 and_return。

controller.stub(:get_video).and_raise(Exception)
