rspec測試失敗：兩個「科目」之間的衝突

Question

我無法通過測試。在我的應用程序中，用戶可以有多個他們請求的會議（sent_meetings）以及他們請求的會議（received_meetings）。

首先，我（簡化）user.rb型號：

user.rb

class User < ActiveRecord::Base 
    attr_accessible :name, :email, :password, :password_confirmation 
    has_secure_password 

    has_many :sent_meetings, :foreign_key => "requestor_id", :class_name => "Meeting" 
    has_many :received_meetings, :foreign_key => "requestee_id", :class_name => "Meeting" 
end 

而且我meeting.rb型號：

meeting.rb

class Meeting < ActiveRecord::Base 
    attr_accessible :intro, :proposed_date, :proposed_location 

    belongs_to :requestor, class_name: "User" 
    belongs_to :requestee, class_name: "User" 
end 

我的測試：

meeting_spec.rb

require 'spec_helper' 

describe Meeting do 

    let(:requestee) { FactoryGirl.create(:user) } 
    let(:requestor) { FactoryGirl.create(:user) } 

    before { @received_meeting = requestee.received_meetings.build(intro: "Lorem ipsum") } 
    before { @sent_meeting = requestor.sent_meetings.build(intro: "Lorem ipsum") } 

    subject { @sent_meeting } 
     it { should respond_to(:intro) } 
     it { should respond_to(:requestor_id) } 
     it { should respond_to(:requestor) } 
     its(:requestor) { should == requestor } 
     # it { should be_valid } 

    subject { @received_meeting } 
    it { should respond_to(:intro) } 
    it { should respond_to(:requestee_id) } 
    it { should respond_to(:requestee) } 
    its(:requestee) { should == requestee } 
    # it { should be_valid } 

end 

似乎是在我的規格文件（@sent_meeting和@received_meeting）兩個「主題」行之間的衝突，以及一個覆蓋另一個。這是我失敗的測試消息：

失敗：

1）會議請求 故障/錯誤：它（：請求者）{應==請求者} 預期：＃ 有：無（使用==） ＃./spec/models/meeting_spec.rb:15:in`塊（2級）在'

在0.67458秒 36個實例成品，1次失敗

失敗的例子：

rspec的./spec/models/meeting_spec.rb:15＃會議請求

我發現有趣的是，我得到這個錯誤只爲要麼請求者或請求方（顯然有衝突）。兩個主題代碼塊的順序很重要，當我切換它們時，我會得到與上面相同的錯誤，但對於'請求者'而不是'請求者'。

我怎樣才能通過測試？謝謝！

Answer 1

你不能這樣做。你必須這樣做：

require 'spec_helper' 

describe Meeting do 

    let(:requestee) { FactoryGirl.create(:user) } 
    let(:requestor) { FactoryGirl.create(:user) } 

    before { @received_meeting = requestee.received_meetings.build(intro: "Lorem ipsum") } 
    before { @sent_meeting = requestor.sent_meetings.build(intro: "Lorem ipsum") } 

    describe "sent meetings" do 
    subject { @sent_meeting } 
    it { should respond_to(:intro) } 
    it { should respond_to(:requestor_id) } 
    it { should respond_to(:requestor) } 
    its(:requestor) { should == requestor } 
    it { should be_valid } 
    end 

    describe "received meetings" do 

    subject { @received_meeting } 
    it { should respond_to(:intro) } 
    it { should respond_to(:requestee_id) } 
    it { should respond_to(:requestee) } 
    its(:requestee) { should == requestee } 
    # it { should be_valid } 
    end 

end 

你也可以使用讓前，而不是像這樣：

require 'spec_helper' 

describe Meeting do 

    let(:requestee) { FactoryGirl.create(:user) } 
    let(:requestor) { FactoryGirl.create(:user) } 
    let(:received_meeting) { requestee.received_meetings.build(intro: "Lorem ipsum") } 
    let(:sent_meeting) { requestor.sent_meetings.build(intro: "Lorem ipsum") } 

    describe "sent meetings" do 
    subject { sent_meeting } 
    it { should respond_to(:intro) } 
    it { should respond_to(:requestor_id) } 
    it { should respond_to(:requestor) } 
    its(:requestor) { should == requestor } 
    it { should be_valid } 
    end 

    describe "received meetings" do 
    subject { received_meeting } 
    it { should respond_to(:intro) } 
    it { should respond_to(:requestee_id) } 
    it { should respond_to(:requestee) } 
    its(:requestee) { should == requestee } 
    it { should be_valid } 
    end 

end 

它會更快。
