问题描述
尝试测试我的函数是否能正确地从异常中拯救出来,更改参数(文件名),然后再试一次.我可以让函数接收第一次尝试,但无法接收第二次尝试.
Trying to test that my function will properly rescue from an exception, change the parameters (filename), and try again one time. I can get the function to receive the first try, but can't get it to receive the 2nd attempt.
控制器
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
规格
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?
Tried a few things but nothing works. Any thoughts?
提前致谢!
推荐答案
你应该使用 and_raise
而不是 and_return
.
You should use and_raise
not and_return
.
controller.stub(:get_video).and_raise(Exception)
