Rails，Cucumber，Capybara：session不会持久化 [英] Rails, Cucumber, Capybara: session is not persisted

问题描述

我试图写一个依赖于一些会话存储数据的功能的测试，我的场景看起来像这样：

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

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"

通过使用调试器我发现，正确地存储在会话中，但对于每个新请求，我都会得到一个新的会话。

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.

至少每个场景都应该有一个工作会话？任何想法为什么不是这种情况？

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

感谢提前，
Joe

Thanks in advance, Joe

推荐答案

的驱动程序没有清楚的设置cookie的方式。这是一个奇怪的解决方法，直到他们被整理出来：

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

  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
