水豚的多个会话

Question

背景

我想在我的网络应用程序上测试以多个用户身份登录，我正在使用 Cucumber 和 capybara 来执行此操作。我找到了关于如何处理多个会话的 this link，但不幸的是，cucumber 似乎无法找到定义的 in_session 方法。我怎样才能访问它？

黄瓜场景

Given I go to teacher login in Steve's browser

When I enter "Steve" in the username field 
     And I enter "StevesPassword" in the password field 
     And I click login 
Then I should see "Steve Lastname" as the current user

When I go to teacher login in Lisa's browser
     And I enter "Lisa" in the username field 
     And I enter "LisasPassword" in the password field 
     And I click login 
Then I should see "Lisa Lastname" as the current user

Ruby代码

#standard_definitions/switching_sessions.rb
When /^(.*) in (.*) browser$/ do |next_step, name|
    in_session(name) do
        step next_step
    end 
end

  #features/support/sessions.rb
  module Capybara
  module Driver
    module Sessions
      def set_session(id)
        Capybara.instance_variable_set("@session_pool", {
          "#{Capybara.current_driver}#{Capybara.app.object_id}" => $sessions[id]
        })
      end

      def in_session(id, &block)
        $sessions ||= {}
        $sessions[:default] ||= Capybara.current_session
        $sessions[id]       ||= Capybara::Session.new(Capybara.current_driver, Capybara.app)
        set_session(id)

        yield

        set_session(:default)
      end
    end
  end
end

错误

当我运行这样做时，我得到以下信息：

Scenario: multiple users                                  # features/Provebank/Provebank.feature:23
Given I go to teacher login in Steve's browser         # features/step_definitions/standard_definitions/switching_sessions.rb:5
  undefined method `in_session' for Capybara::Driver::Sessions:Module (NoMethodError)
  ./features/step_definitions/standard_definitions/switching_sessions.rb:8:in `/^(.*) in (.*) browser$/'
  features/test.feature:24:in `Given I go to teacher login in Steve's browser'

Answer 1

如文章顶部所述，您 link 编辑了 "This is now included in the Capybara library." - 除了该方法被命名为 Capybara.using_session 而不是 in_session，因此您不需要features/support/session.rb。请注意，您的测试编写方式以及您共享的 link 中的代码，只有以 "in xxxx's browser" 结尾的步骤实际上会出现在不同的会话中，而不是您在这些行下标记的步骤.要使这些步骤组中的每组都在它们自己的会话中发生，您需要在每一行上使用 "in xxx's browser"，或者在一个步骤中使用 Capybara.session_name = <name>，然后将其用于以后的步骤。如果直接设置 session_name 如果您希望将来的场景默认为该会话，您可能希望在 After 块中将其重置为 :default。

# only next_step will be executed in the alternate session
When /^(.) in (.*) browser$/ do |next_step, name|
  Capybara.using_session(name) do
     step next_step
  end 
end

# all future steps will be executed in the alternate session
# you probably want to reset this to :default in an After block
Given /^I switch to (.*) browser$/ do |name|
  Capybara.session_name = name
end

Answer 2

如果我正确理解了你的问题，那么一种方法是将 Capybara 会话重命名为：

user1 = Capybara::Session.new(:selenium)
user1.visit "foo/bar"

user2 = Capybara::Session.new(:selenium)
user2.visit "bar/foo"
user1.click_on "Sign in"
user2.click_on "Log in"

等等

另请查看 rack_session_access gem。也许这就是您要找的东西？
