Rubyonrails 判断 Select 框与 Capybara 有某些选项

发布于11月22日

如何使用水豚来判断 Select 框是否有某些列为选项的值？

这是我的HTML:

<select id="cars"> 
  <option></option>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

这就是我想做的:

Then the "cars" field should contain the option "audi"

推荐答案

try 改用水豚rspec matcher have_select(locator, options = {}):

#Find a select box by (label) name or id and assert the given text is selected
Then /^"([^"]*)" should be selected for "([^"]*)"$/ do |selected_text, dropdown|
  expect(page).to have_select(dropdown, :selected => selected_text)
end

#Find a select box by (label) name or id and assert the expected option is present
Then /^"([^"]*)" should contain "([^"]*)"$/ do |dropdown, text|
  expect(page).to have_select(dropdown, :options => [text])
end
