网络老鼠 +野科切 + CSS 选择器 +空格=噩梦

Question

我需要使用 Cucumber/Webrat 测试此按钮的存在：

<%=submit_tag 'Get it'%>

但是当我使用此自定义步骤时：

And I should see a button with a value of "Get it"

即：

Then /^I should see a button with a value of "([^\"]*)"$/ do |value|
 response.should have_selector("form input[value=#{value}]")
end

我得到：

    And I should see a button with a value of "Get it"                       # features/step_definitions/common_steps.rb:181
      unexpected ' ' after 'includesGet' (Nokogiri::CSS::SyntaxError)
      /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `_racc_do_parse_c'
      /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `__send__'
      /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `do_parse'
      ./features/step_definitions/common_steps.rb:182:in `/^I should see a button with a value of "([^\"]*)"$/'

当我使用一个单词值测试按钮时，它可以工作，所以它是“Get”和“it”之间的空格。

有想法吗？

谢谢

Answer 1

And I should see a button named "Get it"

custom_steps.rb

Then /^I should see a button named "([^\"]*)"$/ do |name|
 response.should have_xpath("//input[@type='submit' and @value='#{name}']")
end

对我来说，这似乎是 Nokogiri 的一个问题：

page.search("input[value='Next Batch']")   # => Nokogiri::CSS::SyntaxError
page.search("//input[@value='Next Batch']") # => Okay
