Overview

A Simple is a simpler version of Base which includes only Finders and Matchers and does not include Actions. This type of node is returned when using Capybara.string.

It is useful in that it does not require a session, an application or a driver, but can still use Capybara’s finders and matchers on any string that contains HTML.
