Ruby on rails 使用RubyonRails获取Flexmock断言以触发失败的Rspec测试

Ruby on rails 使用RubyonRails获取Flexmock断言以触发失败的Rspec测试,ruby-on-rails,testing,rspec,rspec2,Ruby On Rails,Testing,Rspec,Rspec2,使用RSpec(2.5.0)和flexmock,我发现即使我告诉flexmock对象它永远不会收到方法,我的测试还是通过了 require File.expand_path(File.dirname(__FILE__) + '/../spec_helper') class Foo end describe Foo do describe "flexmock" do it 'should fail when a method is called too many times

使用RSpec(2.5.0)和flexmock,我发现即使我告诉flexmock对象它永远不会收到方法,我的测试还是通过了

require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
class Foo
end

describe Foo do 

  describe "flexmock" do

      it 'should fail when a method is called too many times' do
        f = flexmock(:foo => :bar)
        f.should_receive(:foo).never
        f.foo
        ## this test should fail, but doesn't        

      end

  end
end

虽然这是一个人为的例子,但我希望用flexmock做一些事情,比如确保发送电子邮件

flexmock(电子邮件)。应收到(:朋友请求)。一次

在其他方法中,但是如果flexmock对象没有告诉rspec它的标准没有得到满足,那么这并不能真正帮助我

有没有办法让Flexmock在未达到预期时触发失败的rspec测试
