rspec测试失败：两个“科目”之间的冲突

Question

我无法通过测试。在我的应用程序中，用户可以有多个他们请求的会议（sent_meetings）以及他们请求的会议（received_meetings）。

首先，我（简化）user.rb型号：

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型号：

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 

我的测试：

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 

似乎是在我的规格文件（@sent_meeting和@received_meeting）两个“主题”行之间的冲突，以及一个覆盖另一个。这是我失败的测试消息：

失败：

1）会议请求 故障/错误：它（：请求者）{应==请求者} 预期：＃ 有：无（使用==） ＃./spec/models/meeting_spec.rb:15:in`块（2级）在'

在0.67458秒 36个实例成品，1次失败

失败的例子：

rspec的./spec/models/meeting_spec.rb:15＃会议请求

我发现有趣的是，我得到这个错误只为要么请求者或请求方（显然有冲突）。两个主题代码块的顺序很重要，当我切换它们时，我会得到与上面相同的错误，但对于'请求者'而不是'请求者'。

我怎样才能通过测试？谢谢！

你不能这样做。你必须这样做：

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 

你也可以使用让前，而不是像这样：

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 

它会更快。
