Question

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）并且它被描述为Anti-Pattern。

如何继续使用唯一字段的排序，然后测试正确的值？

您可以在我的代码中看到......

我必须调用FactoryGirl.reload，以便在1开始时增量开始，以防任何先前的测试已经运行。
我必须声明:count => 1，因为只会有一个该值的实例。

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/客户端/ 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 => "email1@example.com".to_s, :count => 1
    assert_select "tr>td", :text => "username1".to_s, :count => 1
  end
end

如何为此特定测试传递特殊名称？

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

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