Overview

SitePrism::Page

SitePrism Pages are the top level construct of the POM framework

Instances of this class represent a full web page that can either be dynamically navigated to through clicking buttons or filling in fields, or verbosely loaded by using the ‘#load` method

All method calls made whilst on a page are scoped using ‘#to_capybara_node` which defaults to the current Capybara session or the `@page` that has been loaded in-line

end

.set_url_matcher(page_url_matcher) ⇒ Regexp

Sets and returns the specific url matcher that will be used to validate the page is loaded

# File 'lib/site_prism/page.rb', line 32

def set_url_matcher(page_url_matcher)
  @url_matcher = page_url_matcher
end

.url_matcher ⇒ Regexp || String

The specific url matcher that is used to validate the page is loaded. When one hasn’t been previously set, use the url that was set as a direct Regexp exact matcher

#load(expansion_or_html = {}, &block) ⇒ Object

Loads the page. The page will yield the block if defined.

Executes the block, if given. Runs load validations on the page, unless input is a string

When calling #load, all the validations that are set will be ran in order

end

#url(expansion = {}) ⇒ NilClass || String

Returns the templated url from the set_url property defined during the page definition Returns ‘nil` if there was not a property set (i.e. the page should not be directly loaded)

end

#url_matches(seconds = Capybara.default_max_wait_time) ⇒ Nil || MatchData || Hash

Return the matching information of a page

Return nil if the page is not displayed correctly Return the regex matches if we have provided a regexp style url_matcher Otherwise fall back to an addressable-style template of matches

  return regexp_backed_matches if url_matcher.is_a?(Regexp)

  template_backed_matches
end

#wait_until_displayed(*args) ⇒ Boolean

Wait until the page is displayed according to input arguments If no url_matcher is provided we don’t know how to determine if the page is displayed. So we return an error Then we wait until the url matches the expected mappings
