Capybara Selenium WebDriver没有看到我的测试数据

Question

我的测试数据库对象不能被Capybara Selenium WebDriver查看。有没有人看到我的设置有问题或我可能错过了什么？

rails_helper.rb

... 
RSpec.configure do |config| 

    config.use_transactional_fixtures = false 
    ... 
end 

database_clearner.rb

RSpec.configure do |config| 

    config.use_transactional_fixtures = false 

    config.before(:suite) do 
    DatabaseCleaner.clean_with(:truncation) 
    end 

    config.before(:each) do 
    DatabaseCleaner.strategy = :transaction 
    end 

config.before(:all) do 
    DatabaseCleaner.start 
end 

config.before(:each, type: :feature) do 
    # :rack_test driver's Rack app under test shares database connection 
    # with the specs, so continue to use transaction strategy for speed. 
    driver_shares_db_connection_with_specs = Capybara.current_driver == :rack_test 

    if !driver_shares_db_connection_with_specs 
    # Driver is probably for an external browser with an app 
    # under test that does *not* share a database connection with the 
    # specs, so use truncation strategy. 
    DatabaseCleaner.strategy = :truncation 
    end 
end 

config.before(:each, :js => true) do 
    DatabaseCleaner.strategy = :truncation 
end 

config.before(:each) do 
    DatabaseCleaner.start 
end 

config.append_after(:each) do 
    DatabaseCleaner.clean 
end 

config.after(:all) do 
    DatabaseCleaner.clean 
end 

end 

external_user_viewing_resources_sel_spec.rb

require 'rails_helper' 
require 'support/selenium_helper' 

RSpec.feature "External user " do 

before(:all) do 
    get_driver 
    login_user(:external_user) 
end 

after(:all) do 
    #@driver.find_element(:id, "logout").click() 
    #quit_driver 
end 

scenario "can view and click resources (helpful links)", js: true do 
    @d1_inst_resource = create(:d1_inst_resource) 
    puts @d1_inst_resource.inspect 
    @driver.find_element(:id, 'helpful_links_panel') 
    @driver.find_element(:id, "#{@d1_inst_resource.id}").click(); 
end 
end 

selenium_helper.rb

require 'selenium-webdriver' 

def get_driver 
    Capybara.current_driver = Selenium::WebDriver.for :firefox #:chrome 
    @driver = Capybara.current_driver 
end 

def quit_driver 
    @driver.quit 
    Capybara.use_default_driver 
end 

def login_user(user) 
    @user = build_stubbed(user) 
    @driver.get "http://localhost:3000" 
    @driver.find_element(:id, "username").send_keys("#{@user.email}") 
    @driver.find_element(:id, "password").send_keys("#{@user.password}") 
    @driver.find_element(:css, "button[type='submit']").click() 
end 

错误

Selenium::WebDriver::Error::NoSuchElementError: 
    Unable to locate element: {"method":"id","selector":"10534"} 

我见过的其他物品，但他们不解决我的问题。据我所知，他们在不同的线程中运行，但我觉得上面的配置已经采取的是照顾......

Capybara with :js => true causes test to fail

*****更新的代码*****

selenium_helper.rb

def login_user(user) 
    @user = build_stubbed(user) 
    page.visit "/" 
    page.fill_in "username", with: @user.email 
    page.fill_in "password", with: @user.password 
    page.find("button[type='submit']").click()

更改我的database_cleaner .rb文件修复了这个问题，它们不再运行在两个不同的线程中。

RSpec.configure do |config| 
    config.use_transactional_fixtures = false 

    config.before :each do 
    if Capybara.current_driver == :rack_test 
     DatabaseCleaner.strategy = :transaction 
    else 
     DatabaseCleaner.strategy = :truncation 
    end 
    DatabaseCleaner.start 
    end 

    config.after do 
    DatabaseCleaner.clean 
    end 
end

你没有看到这个资源，因为它没有被创建，直到这个页面已经被加载完毕，然而你也没有真正在你的例子中使用Capybara，因为你完全绕过了它并直接使用了selenium实例。

在get_driver当你想要一个与Capybara注册的驱动程序匹配的符号时，你将Capybara.current_driver设置为Selenium :: WebDriver的一个实例。在`login_user'中，你正在创建一个存根对象（即不是真正的/保存到数据库），然后使用它登录，这将无法工作，因为数据库中没有用户要加载应用程序线程。我可能不理解你想要做什么，但我希望你的文件看起来更像

external_user_viewing_resources_sel_spec.rb

require 'rails_helper' 
require 'support/selenium_helper' 

RSpec.feature "External user " do 

before(:each) do 
    login_user(:external_user) 
end 

scenario "can view and click resources (helpful links)", js: true do 
    @d1_inst_resource = create(:d1_inst_resource) 
    page.visit("whatever page should should show the record") 
    page.find(:id, @d1_inst_resource.id").click(); 
    # some check for what should happen based on the click 
end 
end 

selenium_helper.rb

def login_user(user) 
    @user = create(user) 
    page.visit "http://localhost:3000" #Is this meant to be a different system than the app under test? if not it should just be page.visit '/' 
    page.fill_in("username", with: @user.email) 
    page.fill_in("password", with: @user.password) 
    page.find(:css, "button[type='submit']").click() 
    #some check for whatever happens on the page to show the user has logge in 
end
