失敗RSpec的測試 - 不被創建的對象

Question

我有以下的測試代碼：

require 'spec_helper' 
require 'matchers/be_valid_verbose' 

describe User do 

before do 
    @user = User.new(first_name: "First", last_name: "Last", email: "test@test.com", role: "admin", 
        password: "foobar12", password_confirmation: "foobar12") 
end 
subject (@user) 

specify { should be_valid_verbose } 

describe "return value of authendicate method" do 
    before { @user.save } 
    let(:found_user) { User.find_by_email(@user.email) } 

    describe "with valid password" do 
     it { should == found_user.authenticate(@user.password) } 
    end 

     describe "with invalid password" do 
      let(:user_for_invalid_password) { found_user.authenticate("invlaid") } 

      it { should_not == user_for_invalid_password } 
      specify { user_for_invalid_password.should be_false } 
    end 
end 

末

我不明白爲什麼：它應該{} be_valid是gettig一個完全空的用戶目的。在before do語句中創建用戶對象後，我嘗試使用find_by_email時也是如此。 這裏是我的測試輸出

$ bundle exec rspec spec/models/user_trial_spec.rb 
FF..

好吧，我剛纔看到的問題。我用

subject (@user) 

而不是正確的

subject { @user } 

DOH！
