# 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.
|
|
#

|
|
# @yield A block executed in the context of the new {Capybara::Selector}

#
|
|
# Modify a selector previously craeated by {Capybara.add_selector}.
|
|
# For example modifying the :button selector to also find divs styled
|
|
# to look like buttons might look like this
|
|
#
|
|
# Capybara.modify_selector(:button) do
|
|
