📌 Capybara all does not return an array
Although it looks like it returns an Array, Capybara's all finder actually
returns a Capybara::Result. This object includes Enumerable and responds to
many of the most used methods on Array such as [].
Given the following HTML:
<body>
<p>Some content</p>
<p>Other content</p>
<p>Final content</p>
</body>
The following really looks like we are dealing with an array:
paragraphs = all("p")
# => [<Capybara::Element>,<Capybara::Element>,<Capybara::Element>]
paragraphs[1]
# => <Capybara::Element>
paragraphs.map(&:text)
# => ["Some content", "Other content", "Final Content"]
However, if I try to use some of the Array monkey patches provided by
ActiveSupport:
paragraphs.second
# => NoMethodError: undefined method `second' for Capybara::Result
paragraphs.class
# => Capybara::Result
