模拟Rails控制器规范中的外部类

Question

我有一个使用RSpec测试的Rails 3应用程序。我已经使用外部类MustMock作为

class FooController < ApplicationController 
    def myaction 
    mockme = MustMock.new 
    @foobar = mockme.do_something 
    end 
end 

我怎样才能最好地嘲笑的MustMock实例在我的控制器规格控制器？

Answer 1

describe FooController do 
    specify :myaction do 
    MustMock.should_receive(:new) 
      .and_return(stub :do_something => :something) 
    get :myaction 
    assigns[:foobar].should == :something 
    end 
end 

Answer 2

你可以试试这个：

it "does something in myaction" do 
    my_stub = stub() 
    my_stub.should_receive(:do_something).once.and_return(:foobar) 
    MustMock.stub(:new => my_stub) 
    get :myaction 
    response.should be_success 
end
