什么是“应该”？在 Rspec 中？为什么 `should redirect_to` 有效？
Rspec 有很多魔力。我不知道应该是什么以及如何使用它。
response.should redirect_to(some_path)
Rdoc 说 should 可以是使用 ==、===、~= 和匹配器（它是什么？）调用。我猜 redirect_to(some_path) 是匹配器。
但这意味着什么呢？这个redirect_to和ActionController::Redirecting#redirect_to一样吗？ should 可以知道 Rails 是否调用此方法吗？
还有其他的事情......
should render_template
should have_text
render_template 是 ActionView::LogSubscriber#render_template 吗？那么任何 Rails 方法都可以附加在 should 之后吗？而且，Rails 没有 have_text 方法，那么它是什么呢？为什么应该知道？
Rspec has a lot of magics. I can't find out what should is and how to use it.
response.should redirect_to(some_path)
The Rdoc says should can be called with ==, ===, ~=, and a matcher(what is it?). I guess redirect_to(some_path) is the matcher.
But what does it mean? This redirect_to is the same as the ActionController::Redirecting#redirect_to? Can should know whether Rails calls this method?
And the other things...
should render_template
should have_text
Is render_template the ActionView::LogSubscriber#render_template? So any Rails method can be attached after should? Moreover, Rails doesn't have the method have_text, so what is it? Why does should know?

不，
redirect_to是另一回事。您在执行should redirect_to()时使用的是这个匹配器 - http://relishapp.com/rspec/rspec-rails/v/2-6/dir/matchers/redirect-to-matcher与 < 相同一个href="http://relishapp.com/rspec/rspec-rails/v/2-6/dir/matchers/render-template-matcher" rel="nofollow">render_template
No, that
redirect_tois a different thing. The one you're using when doingshould redirect_to()is this matcher - http://relishapp.com/rspec/rspec-rails/v/2-6/dir/matchers/redirect-to-matcherSame with render_template
