SampleApp::Application.routes.draw do

    match '/signup', to: 'users#new',   via: 'get'

我觉得apneadiving是对的，它看起来应该是小写字母。我也看看GitHub code for the tutorial

describe "with valid information" do 
     let(:user) { FactoryGirl.create(:user) } 
     before do 
     fill_in "Email", with: user.email.upcase 
     fill_in "Password", with: user.password 
     click_button "Sign in" 
     end 

它也有小写。根据David Flanagan，Yukihiro Matsumoto的Ruby编程语言书，只要确定我也检查了Ruby是一种区分大小写的语言。
