如何在工厂中使用’sequence’来避免使用’FactoryGirl.reload’？

必须使用FactoryGirl.reload可能会花费一些开销来运行所有测试（当存在许多测试时），并且它也被描述为反模式 。

如何继续使用唯一字段的排序，然后测试正确的值？

你可以在我的代码中看到……

• 我必须调用FactoryGirl.reload以便在任何先前的测试已经运行的情况下，增量从1开始。

• 我必须声明:count => 1因为只有一个该值的实例。

规格/工厂/ clients.rb

 FactoryGirl.define do factory :client do name "Name" sequence(:email} { |n| "email#{n}@example.com" } sequence(:username) { |n| "username#{n}" } end end 

规格/客户/ index.html.erb_spec.rb

 require 'spec_helper' describe "clients/index" do before do FactoryGirl.reload (1..5).each do FactoryGirl.create(:client) end @clients = Client.all end it "renders a list of clients" do render # Run the generator again with the --webrat flag if you want to use webrat matchers assert_select "tr>td", :text => "Name".to_s, :count => 5 assert_select "tr>td", :text => "[e-mail]".to_s, :count => 1 assert_select "tr>td", :text => "username1".to_s, :count => 1 end end 

Answer 1

如何为这个特定的测试传递特殊名称？

 require 'spec_helper' describe "clients/index" do before do (1..5).each do |num| FactoryGirl.create(:client, username: "special#{num}") end @clients = Client.all end it "renders a list of clients" do render assert_select "tr>td", :text => "special1".to_s, :count => 1 end end 

Answer 2

添加到mind.blank的答案…如果您希望测试增量值，也可以将它们放在增量循环中。

  it "renders a list of clients" do render (1..5).each do |num| assert_select "tr>td", :text => "special#{num}".to_s, :count => 1 end end
