describe AdminController do  
integrate\_views

before(:each) do  
@params = {:login =\> ‘username’, :pass =\> ‘password’, :code\_image =\>  
“1234”}  
end

it “should redirect after input login and pass” do  
session.should\_receive(:[]).with(:code).and\_return(“1234”) # this  
does’nt work!!!  
#session.stub!(:[]).with(:code).and\_return “1234”  
Admin.should\_receive(:authenticate).with(params[:login],  
params[:pass]).and\_return(true)  
post ‘/’, @params  
response.should be\_redirect  
end

end

错误提示是：
