我对如何使用新expect语法模拟类方法感到困惑.这有效:

Facebook
  .should_receive(:profile)
  .with("token")
  .and_return({"name" => "Hello", "id" => "14314141", "email" => "hello@me.com"})

这不是:

facebook = double("Facebook")
allow(facebook).to receive(:profile).with("token").and_return({"name" => "Hello", "id" => "14314141", "email" => "hello@me.com"})

谁能告诉我这里有什么问题？
