Check select box has certain options with Capybara
提问by Tom Maeckelberghe
How do I use Capybara to check that a select box has certain values listed as options? It has to be compatible with Selenium...
如何使用 Capybara 检查选择框是否将某些值列为选项？它必须与硒兼容...
This is the HTML that I have:
这是我拥有的 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>
This is what I want to do:
这就是我想要做的：
Then the "cars" field should contain the option "audi"

Try using the capybara rspec matcher have_select(locator, options = {})instead:
尝试使用水豚 rspec 匹配器have_select(locator, options = {})代替：
#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

For what it's worth, I'd call it a drop-down menu, not a field, so I'd write:
就其价值而言，我将其称为下拉菜单，而不是字段，因此我会这样写：
Then the "cars" drop-down should contain the option "audi"
To answer your question, here's the RSpec code to implement this (untested):
要回答您的问题，这是实现此功能的 RSpec 代码（未经测试）：
Then /^the "([^"]*)" drop-down should contain the option "([^"]*)"$/ do |id, value|
page.should have_xpath "//select[@id = '#{id}']/option[@value = '#{value}']"
end
If you want to test for the option text instead of the value attribute (which might make for more readablescenarios), you could write:
如果要测试选项文本而不是 value 属性（这可能会使场景更具可读性），您可以编写：
page.should have_xpath "//select[@id = '#{id}']/option[text() = '#{value}']"

As an alternative solution, and as I'm not familiar with xpaths, I did this to solve a similar problem:
作为替代解决方案，由于我不熟悉 xpaths，我这样做是为了解决类似的问题：
page.all('select#cars option').map(&:value).should == %w(volvo saab mercedes audi)
Its quite simple, but took me some time to figure out.
它很简单，但我花了一些时间才弄明白。

Well, since i was around and saw the question (and been testing today) decided to post my way:
好吧，因为我在附近看到了这个问题（今天一直在测试）决定发布我的方式：
within("select#cars") do
%w(volvo saab mercedes audi).each do |option|
expect(find("option[value=#{option}]").text).to eq(option.capitalize)
end
end

Then I should see "audi" within "#cars"
should do the trick
应该做的伎俩
