Rails、Cucumber、Capybara:会话不持久

问题描述

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:

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.

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议吗?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?

提前致谢，乔

推荐答案

由于 capybara 在测试中切换主机名，我们遇到了丢失会话的问题.场景类似于以下内容:

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:

# 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 为 capybara 设置新主机！'newhost.org'

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'
