Advantages of MiniTestPlugin?

[toppsdown]

Thanks for this Gem! It's working well and I really appreciate it.

I have a question about the Readme, specifically the following note:

Also, consider adding include Capybara::Screenshot::MiniTestPlugin to any test classes that fail. For example, to capture screenshots for all failing integration tests in minitest-rails, try something like:

class ActionDispatch::IntegrationTest
  include Capybara::Screenshot::MiniTestPlugin
  # ...
end

What does including the MiniTestPlugin do? what extra features does it provide? Just trying to figure out if I should include it or not

Thanks!
