Rails，Cucumber，Capybara：会话不会持续存在

I'm trying to write a test for a feature that relies on some session stored data and my scenario looks like this:

我正在尝试为依赖于某些会话存储数据的功能编写测试,我的场景如下所示:

Scenario: Create offer
  Given I am on the start offer page
  When I select "Foo" from "bar"
  And I press "Go on"
  Then I should see "You are going to offer foo"

By using the debugger I found out, that the information is stored in the session correctly, but on every new request I get a fresh session.

通过使用我发现的调试器,信息正确地存储在会话中,但是在每个新请求中我都会获得一个新的会话。

Should'nt there be a working session for at least every scenario? Any ideas why this isn't the case?

至少在每个场景中都不应该有工作会话吗?任何想法为什么不是这样的?

Thanks in advance, Joe

在此先感谢,乔

We had the problem with loosing the session due to capybara switching the host name in mid-test. The scenario was something like the following:

由于水豚在测试中期切换主机名,我们遇到了丢失会话的问题。场景如下:

# Good
When I visit some page
# will call 'http://capybarawhatever/some_page
And I click the the button
# will call 'http://capybarawhatever/some_new_page'
Then I still have the session

# Failing
When I visit some page
# will call 'http://capybarawhatever/some_page'
And I do something that redirects me to "http://newhost.org/new_page"
And I visit some page
# No this may go to 'http://newhost.org/some_page
Then I have lost my session

This may be worth investigating. You can get the current_url in your session, and you may set a new host for capybara using host! 'newhost.org'

这可能值得研究。你可以在你的会话中获得current_url,你可以使用host为capybara设置一个新的主机! 'newhost.org'

Some of the drivers don't have a clear way of setting cookies. This is a hacky workaround until they are sorted out:

一些驱动程序没有明确的设置cookie的方法。这是一个hacky解决方法,直到它们被整理出来:

  def set_cookie(name, value, domain)
    driver = Capybara.current_session.driver rescue nil

    return unless driver

    case driver
    when Capybara::Driver::RackTest
      driver.set_cookie "#{name}=#{value}"
    when Capybara::Driver::Selenium
      visit '/' # must visit the domain before we can set the cookie

      br = driver.browser.send(:bridge)

      br.addCookie({
        'name'    => name,
        'domain'  => domain,
        'value'   => value,
        'path'    => '/',
        'expires' => (Time.now + 100.years).to_i
      })
    else
      raise "Unsupported driver #{driver}"
    end
  end
