Previously we were calling the `take_failed_screenshot` method in an `after_teardown` hook. However, this means that other teardown hooks have to be executed before we take the screenshot. Since there can be dynamic updates to the page after the assertion fails and before we take a screenshot, it seems desirable to minimize that gap as much as possible. Taking the screenshot in a `before_teardown` rather than an `after_teardown` helps with that, and has a side benefit of allowing us to remove the nested `ensure` commented on here: https://github.com/rails/rails/pull/34411#discussion_r232819478 |

= Action Pack -- From request to response
Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.
It consists of several modules:
* Action Dispatch, which parses information about the web request, handles
routing as defined by the user, and does advanced processing related to HTTP
such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
handling HTTP caching logic, cookies and sessions.
* Action Controller, which provides a base controller class that can be
subclassed to implement filters and actions to handle requests. The result
of an action is typically content generated from views.
With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.
You can read more about Action Pack in the {Action Controller Overview}[https://guides.rubyonrails.org/action_controller_overview.html] guide.
