DEFAULT_CONFIGURATION = 
{
  helpers_paths: ['test_helpers'].freeze,

SKIPPED_DSL_METHODS =

Internal: Methods that are in the Capybara DSL but are so common that we don’t want to issue a warning if they are used as selectors.

[

  :body,
  :html,
].freeze
RESERVED_METHODS =

Internal: Methods that should not be overiden or used as locator aliases to avoid confusion while working on test helpers.

METHODS_EXPECTING_A_HASH =

Internal: Ruby 2.7 swallows keyword arguments, so for methods that take a Hash as the first argument as well as keyword arguments, we need to manually detect and move them to args if empty.
