在Capybara的多个场景中重用Factory_Girl生成的列表

Question

我正在使用FactoryGirl gem来生成一组我的模型的实例，用于使用capybara进行测试。目前，测试正在检查过滤器是否工作。第一个测试通过了，但是第二个测试没有通过。

这是要运行测试的apply_filters.rb：

describe "applying filters to the scotland list" do 

 scenario "i apply a minimum income filter" do    
    charities = FactoryGirl.create_list(:scotland, 9)
    visit "/scotsfilter"
    fill_in('Minimum Income', :with => 5)
    click_button('Apply Filters')
    expect(page).to have_no_content(charities[0].Charity_Number)
    expect(page).to have_content(charities[5].Charity_Number)
    expect(page).to have_content(charities[6].Charity_Number)  
 end
 scenario "i apply a maximum income filter" do
    charities = FactoryGirl.create_list(:scotland, 9)
    visit "/scotsfilter"
    fill_in('Maximum Income', :with => 5)
    click_button('Apply Filters')
    expect(page).to have_content(charities[0].Charity_Number)
    expect(page).to have_no_content(charities[5].Charity_Number)
    expect(page).to have_no_content(charities[6].Charity_Number)  
  end
end

这是工厂：

FactoryGirl.define do
  factory :scotland do
    sequence(:id) {|n| n} 
    sequence(:Charity_Number){|n| "MyString#{n} "}
    Charity_Name "MyString"
    Registered_Date "MyString"
    Known_As "MyString"
    Charity_Status "MyString"
    Postcode "MyString"
    Constitutional_Form "MyString"
    Previous_Constitutional_Form_1 "MyString"
    Geographical_Spread "MyString"
    Main_Operating_Location "MyString"
    sequence(:Purposes){|n| "MyString#{n}"}
    sequence(:Beneficiaries){|n| "MyString#{n}"}
    Activities "MyString"
    Objectives "MyString"
    Principal_Office_Trustees_Address "MyString"
    Website "MyString"
    sequence(:Most_recent_year_income){|n| n}
    sequence(:Most_recent_year_expenditure){|n| n}
    Mailing_cycle "MyString"
    Year_end "MyString"
    Parent_charity_name "MyString"
    Parent_charity_number "MyString"
    Parent_charity_country_of_registration "MyString"
    Designated_religious_body "MyString"
    Regulatory_type "MyString"
  end
end

然而，第二个FactoryGirl.create_list(:scotland,9)生成一组从MyString10到MyString19的实例。我希望它使用原始的MyString1到MyString9。我尝试过全局变量，并将charities定义放置在任何地方。为了在即将到来的一系列测试中使用charities，我缺少了什么？

Answer 1

不能在多个测试中重用相同的对象，每个测试之间都会清除数据库，以便将一个测试与另一个测试隔离开来。此外，如果创建的对象的特定值对给定的测试很重要，则在创建对象时应该指定该值，并让工厂处理那些无关紧要的值。

因此，在您的示例测试中，您可能希望类似于

charities = (1..9).map {|income| FactoryGirl.create(:scotland, Most_recent_year_income: income }
