ruby 1.9.3dev (2011-09-23 revision 33323) [i686-linux]

gem 'rails', '3.2.9'

group :test do
  gem 'cucumber-rails', require: false
  gem 'capybara', '~> 2.0.3'
  gem 'rspec-rails'
  gem 'database_cleaner'
  gem 'factory_girl'
  gem "ffaker"
  gem "capybara-firebug", "~> 1.3.0"
  gem 'ruby-debug19'
end

在我的黄瓜步骤之一中，我试图断言下拉元素（<select> 标记）具有使用 Capybara API 和以下代码选择的特定选项。

  within('#myForm') do
    page.has_select?("#event_type", selected: @event_type).should be_true
  end

但是我收到此错误：

   expected: true value
   got: false (RSpec::Expectations::ExpectationNotMetError)

我在我的场景中使用 (capybara-firebug) 的@firebug标签检查了 DOM ，发现在下拉列表中选择了所需的选项（由 @event_type 持有）但是在 DOM 中没有添加“selected”属性到我猜是导致期望失败的选择标签。

我在这里找到了类似的参考：https ://github.com/jnicklas/capybara/issues/171 ，其中提到了有修复的提交，但我猜该提交没有合并到我正在使用的水豚版本中。我正在尝试挖掘源代码并发现https://github.com/jnicklas/capybara/issues/171中提到的修复程序 不存在于 Capybara 的代码库中。

任何机构都可以让我知道如何断言选择标签选择了特定选项吗？

注意：在没有任何版本的 Gem 文件中使用 capybara 时：

gem 'capybara'

Capybara 版本 2.1.0 已启动安装，但失败并出现错误：

capybara requires Ruby version >= 1.9.3

虽然我有所需的红宝石版本。

I don't use cucumber, but in you example

within('#myForm') do
  page.has_select?("#event_type", selected: @event_type).should be_true
end

it depends on your dom, but you don't have to use '#' in the id selector here, and 'selected:' should be the text in the option, not the value.

so it should be (assuming @event_type is what you are displaying for the text)

within('#myForm') do
  page.has_select?("event_type", selected: @event_type).should be_true
end

or i'd prefer

page.should have_select('event_type', selected: @event_type)
