Using rspec to verify an xpath (via capybara/cucumber)

luislavena · September 20, 2011, 11:51pm

I am doing:

page.should have_xpath(“//img[contains(@class, ‘foobar’)]”, :count =>
0)

but cucumber tells me:

expected xpath “//img[contains(@class, ‘foobar’)]” to return something
(RSpec::Expectations::ExpectationNotMetError)

… Shouldn’t this be returning true/false ?

have_xpath is a Capybara matcher that defines its own failure message:

github.com

teamcapybara/capybara/blob/master/lib/capybara/rspec/matchers.rb#L112-114


      
          #   RSpec matcher for select elements.
          #
          #   @see Capybara::Node::Matchers#has_select?
          
          
# @!method have_table(locator = nil, **options, &optional_filter_block)
          #   RSpec matcher for table elements.
          #
          #   @see Capybara::Node::Matchers#has_table?
          
          
%i[checked unchecked].each do |state|
            define_method "have_#{state}_field" do |locator = nil, **options, &optional_filter_block|
              Matchers::HaveSelector.new(:field, locator, **options.merge(state => true), &optional_filter_block)
            end
          end
          
          
# @!method have_checked_field(locator = nil, **options, &optional_filter_block)
          #   RSpec matcher for checked fields.
          #
          #   @see Capybara::Node::Matchers#has_checked_field?
          
          
# @!method have_unchecked_field(locator = nil, **options, &optional_filter_block)

“have_[xpath]” is a custom matcher in Capybara. So, the answer would be
no.

github.com

teamcapybara/capybara/blob/master/lib/capybara/rspec/matchers.rb

# frozen_string_literal: true

require 'capybara/rspec/matchers/have_selector'
require 'capybara/rspec/matchers/have_ancestor'

require 'capybara/rspec/matchers/have_current_path'
require 'capybara/rspec/matchers/match_style'
require 'capybara/rspec/matchers/have_text'
require 'capybara/rspec/matchers/have_title'
require 'capybara/rspec/matchers/become_closed'

module Capybara
  module RSpecMatchers
    # RSpec matcher for whether the element(s) matching a given selector exist.
    #
    # @see Capybara::Node::Matchers#assert_selector
    def have_selector(...)
      Matchers::HaveSelector.new(...)
    end
