# end
#
# #### Configurable options
#
# - **allow_gumbo** (Boolean = `false`) - When `nokogumbo` is available, whether it will be used to parse HTML strings.
# - **always_include_port** (Boolean = `false`) - Whether the Rack server's port should automatically be inserted into every visited URL
# unless another port is explicitly specified.
# - **app_host** (String, `nil`) - The default host to use when giving a relative URL to visit, must be a valid URL e.g. `http://www.example.com`.
# - **asset_host** (String = `nil`) - Where dynamic assets are hosted - will be prepended to relative asset locations if present.
# - **automatic_label_click** (Boolean = `false`) - Whether {Capybara::Node::Element#choose Element#choose}, {Capybara::Node::Element#check Element#check},
# {Capybara::Node::Element#uncheck Element#uncheck} will attempt to click the associated `<label>` element if the checkbox/radio button are non-visible.
# - **automatic_reload** (Boolean = `true`) - Whether to automatically reload elements as Capybara is waiting.
# - **default_max_wait_time** (Numeric = `2`) - The maximum number of seconds to wait for asynchronous processes to finish.
# - **default_normalize_ws** (Boolean = `false`) - Whether text predicates and matchers use normalize whitespace behavior.
# - **default_selector** (`:css`, `:xpath` = `:css`) - Methods which take a selector use the given type by default. See also {Capybara::Selector}.
# - **default_set_options** (Hash = `{}`) - The default options passed to {Capybara::Node::Element#set Element#set}.
# - **enable_aria_label** (Boolean = `false`) - Whether fields, links, and buttons will match against `aria-label` attribute.
# - **enable_aria_role** (Boolean = `false`) - Selectors will check for relevant aria role (currently only `button`).
# - **exact** (Boolean = `false`) - Whether locators are matched exactly or with substrings. Only affects selector conditions
# written using the `XPath#is` method.
# - **exact_text** (Boolean = `false`) - Whether the text matchers and `:text` filter match exactly or on substrings.
# - **ignore_hidden_elements** (Boolean = `true`) - Whether to ignore hidden elements on the page.
# - **match** (`:one`, `:first`, `:prefer_exact`, `:smart` = `:smart`) - The matching strategy to find nodes.
# - **predicates_wait** (Boolean = `true`) - Whether Capybara's predicate matchers use waiting behavior by default.
# - **raise_server_errors** (Boolean = `true`) - Should errors raised in the server be raised in the tests?
# - **reuse_server** (Boolean = `true`) - Whether to reuse the server thread between multiple sessions using the same app object.
# - **run_server** (Boolean = `true`) - Whether to start a Rack server for the given Rack app.
# - **save_path** (String = `Dir.pwd`) - Where to put pages saved through {Capybara::Session#save_page save_page}, {Capybara::Session#save_screenshot save_screenshot},
# {Capybara::Session#save_and_open_page save_and_open_page}, or {Capybara::Session#save_and_open_screenshot save_and_open_screenshot}.
# - **server** (Symbol = `:default` (which uses puma)) - The name of the registered server to use when running the app under test.
# - **server_port** (Integer) - The port Capybara will run the application server on, if not specified a random port will be used.
# - **server_errors** (Array\<Class> = `[Exception]`) - Error classes that should be raised in the tests if they are raised in the server
# and {configure raise_server_errors} is `true`.
# - **test_id** (Symbol, String, `nil` = `nil`) - Optional attribute to match locator against with built-in selectors along with id.
# - **threadsafe** (Boolean = `false`) - Whether sessions can be configured individually.
# - **w3c_click_offset** (Boolean = 'false') - Whether click offsets should be from element center (true) or top left (false)
#
# #### DSL Options
#
# When using `capybara/dsl`, the following options are also available:
#
# - **default_driver** (Symbol = `:rack_test`) - The name of the driver to use by default.
# - **javascript_driver** (Symbol = `:selenium`) - The name of a driver to use for JavaScript enabled tests.

#
# Add a new selector to Capybara. Selectors can be used by various methods in Capybara
# to find certain elements on the page in a more convenient way. For example adding a
# selector to find certain table rows might look like this:
#
# Capybara.add_selector(:row) do
# xpath { |num| ".//tbody/tr[#{num}]" }
# end
#
# This makes it possible to use this selector in a variety of ways:
#
# find(:row, 3)
# page.find('table#myTable').find(:row, 3).text
# page.find('table#myTable').has_selector?(:row, 3)
# within(:row, 3) { expect(page).to have_content('$100.000') }
#
# Here is another example:
#
# Capybara.add_selector(:id) do
# xpath { |id| XPath.descendant[XPath.attr(:id) == id.to_s] }
# end
#
# Note that this particular selector already ships with Capybara.
#
# @param [Symbol] name The name of the selector to add
# @yield A block executed in the context of the new {Capybara::Selector}
#
def add_selector(name, **options, &block)
Capybara::Selector.add(name, **options, &block)
end
##
#
# Modify a selector previously created by {Capybara.add_selector}.
# For example, adding a new filter to the :button selector to filter based on
# button style (a class) might look like this
#
# Capybara.modify_selector(:button) do
# filter (:btn_style, valid_values: [:primary, :secondary]) { |node, style| node[:class].split.include? "btn-#{style}" }
# end
#
#
# @param [Symbol] name The name of the selector to modify
# @yield A block executed in the context of the existing {Capybara::Selector}
#
def modify_selector(name, &block)
Capybara::Selector.update(name, &block)

# <li id="home">Home</li>
# <li id="projects">Projects</li>
# </ul>
# HTML
#
# node.find('#projects').text # => 'Projects'
