Capybara声明下拉列表,其中选择的期望值不起作用

gem 'rails', '3.2.9'

group :test do
  gem 'cucumber-rails', require: false
  gem 'capybara', '~> 2.0.3'

  gem 'database_cleaner'
  gem 'factory_girl'
  gem "ffaker"
  gem "capybara-firebug", "~> 1.3.0"
  gem 'ruby-debug19'
end

在我的一个Cucumber Step中,我试图断言一个下拉元素 (< select>标记)使用Capybara API选择了特定选项 使用以下代码。

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

但是我收到了这个错误:

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

我在我的场景中使用 @firebug 标签(capybara-firebug)检查了DOM 并发现所需的选项(由@event_type持有)正在被选中 但是在DOM中的下拉列表中,“selected”属性没有得到 添加到select标签,我猜这会导致期望失败。

我在这里找到了类似的参考:https://github.com/jnicklas/capybara/issues/171 提到有修复的提交,但我想提交不是 合并到我正在使用的水豚版本。我正在尝试挖掘源代码 并发现https://github.com/jnicklas/capybara/issues/171中提到的修补程序 并没有出现在Capybara的代码库中。

任何正文都可以让我知道如何断言选择标签有一个 是否选择了特定选项?

注意:在我的Gem文件中使用capybara时没有任何版本:

gem 'capybara'

Capybara版本2.1.0已启动安装,但失败并显示错误:

capybara requires Ruby version >= 1.9.3

虽然我有所需的ruby版本。

我不使用黄瓜,但在你的例子中

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

这取决于你的dom,但你不必在id选择器中使用'#', 并且'selected:'应该是选项中的文本,而不是值。

所以它应该是(假设@event_type是你为文本显示的内容)

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

或者我更喜欢

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