Rails、Cucumber、Capybara：会话不持久

Question

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"

通过使用调试器，我发现信息正确地存储在会话中，但在每个新请求上我都会获得一个新会话。

至少每个场景都应该有一个工作会议吗？任何想法为什么不是这种情况？

提前致谢， 乔

Answer 1

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。场景类似于以下内容：

# 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

这可能值得研究。您可以在会话中获取current_url，并且可以使用host! 'newhost.org' 为水豚设置新主机

某些驱动程序没有明确的设置 cookie 的方法。在整理它们之前，这是一个 hacky 解决方法：

  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
