class Capybara::Node::Simple

A {Capybara::Node::Simple} is a simpler version of {Capybara::Node::Base} which includes only {Capybara::Node::Finders} and {Capybara::Node::Matchers} and does not include {Capybara::Node::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.
