水豚的have_selector有哪些选项？ [英] What are the options to Capybara's have_selector?

问题描述

我在RSpec中遇到此错误。 have_selector 是否有任何文档解释选项哈希中的每个键及其确切作用？

I got this error in RSpec. Are there any docs for have_selector that explain each key in the options hash and what exactly it does?

invalid keys :content, should be one of :text, :visible, :between, :count, :maximum, :minimum, :exact, :match, :wait

推荐答案

capybara为rspec提供了此方法。 capybara的文档很难找到问题的答案，所以让我们关注源代码：

capybara provides this method to rspec. capybara's docs don't make it easy to find the answer to your question, so let's follow the source:

have_selector 在 Capybara :: RSpecMatchers 中。它委托给嵌套类 HaveSelector ，后者将委托给方法 assert_selector 。

have_selector is in Capybara::RSpecMatchers. It delegates to the nested class HaveSelector, which delegates to the method assert_selector.

assert_selector 在 Capybara :: Node :: Matchers 中。 （所以方法 has_selector是吗？，尽管那不是rspec调用的。） assert_selector 的rdoc 记录了：count 选项。它还说：它也接受Finders＃all接受的所有选项，例如：text和：visible。点击进入 Finders＃all 最终使我们了解所有选项的文档：

assert_selector is in Capybara::Node::Matchers. (So is a method has_selector?, although that's not what rspec calls.) assert_selector's rdoc documents the :count option. It also says "It also accepts all options that Finders#all accepts, such as :text and :visible." Clicking through to Finders#all finally gets us to the documentation of all the options:

选项哈希（选项）：

• 文本（字符串，正则表达式）—仅查找包含该文本或与该正则表达式匹配的元素


• 可见（布尔值）—仅查找页面上可见的元素。将其设置为错误的查找-不可见和可见的元素。


• count（整数）-预期将找到的精确匹配项


• 最大值（整数）-期望找到的最大匹配数


• 最小值（整数）-期望找到的最小匹配数


• 之间（范围）-找到的匹配数必须在给定范围内


• 精确（布尔值）-控制是否在是表达式中给定XPath完全或部分匹配

• text (String, Regexp) — Only find elements which contain this text or match this regexp
• visible (Boolean) — Only find elements that are visible on the page. Setting this to false finds - invisible and visible elements.
• count (Integer) — Exact number of matches that are expected to be found
• maximum (Integer) — Maximum number of matches that are expected to be found
• minimum (Integer) — Minimum number of matches that are expected to be found
• between (Range) — Number of matches found must be within the given range
• exact (Boolean) — Control whether is expressions in the given XPath match exactly or partially
