# 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}" }
