无头Chrome与Rspec数据库连接不工作

我有一个规格，通过但当我加js: true它失败。无头Chrome与Rspec数据库连接不工作

它失败，因为visit survey_path(survey)之前有一个survey和account然后尝试运行该行visit survey_path(survey)，我得到undefined method surveys for nil:NilClass因为没有账户或调查。

这就像所有东西都从数据库中删除。

我有一个视图内的反应组件，所以我想写它的功能规格，因此我需要js: true的原因。

任何人都知道为什么数据库没有调查和帐户，当我有js: true？

describe '#edit', js: true do 
    let(:new_survey_name) { 'new survey name' } 

    context 'authenticated user' do 
     before do 
     login_as user 

     # Here there is an account and survey. 
     # Then inside the code when Survey#show is hit there is 
     # no account or survey 
     visit survey_path(survey) 
     end 

     it 'can edit survey' do 
     click_link 'Settings' 
     fill_in 'survey[name]', with: new_survey_name 

     click_button 'Save' 
     visit survey_path(survey) 
     expect(page).to have_content(new_survey_name) 
     expect(page).not_to have_content('Status') 
     end 
    end

导轨帮助文件有这个里面

当你运行特性测试，建议使用:truncation清洁方法。只需添加这样的事情你database_cleaner配置：

config.before(:each, type: :feature) do 
    driver_shares_db_connection_with_specs = Capybara.current_driver == :rack_test 

    DatabaseCleaner.strategy = :truncation if !driver_shares_db_connection_with_specs 
end
