def ==(other)
  self.eql?(other) or (other.respond_to?(:base) and base == other.base)
end

- (Object) assert_no_selector(*args) Also known as: refute_selector

Asserts that a given selector is not on the page or current node. Usage is identical to Capybara::Node::Matchers#assert_selector

Query options such as :count, :minimum, :maximum, and :between are considered to be an integral part of the selector. This will return true, for example, if a page contains 4 anchors but the query expects 5:

page.assert_no_selector('a', :minimum => 1) # Found, raises Capybara::ExpectationNotMet
page.assert_no_selector('a', :count => 4)   # Found, raises Capybara::ExpectationNotMet
page.assert_no_selector('a', :count => 5)   # Not Found, returns true

Raises:

def assert_no_selector(*args)
  query = Capybara::Query.new(*args)
  synchronize(query.wait) do
    begin
      result = all(*args)
    rescue Capybara::ExpectationNotMet => e
      return true
    else
      if result.size > 0 || (result.size == 0 && Capybara::Helpers.expects_none?(query.options))
        raise(Capybara::ExpectationNotMet, result.negative_failure_message)
      end
    end
  end
  return true
end

- (Object) assert_selector(*args)

Asserts that a given selector is on the page or current node.

page.assert_selector('p#foo')
page.assert_selector(:xpath, './/p[@id="foo"]')
page.assert_selector(:foo)

By default it will check if the expression occurs at least once, but a different number can be specified.

page.assert_selector('p#foo', :count => 4)

This will check if the expression occurs exactly 4 times. See Finders#all for other available result size options.

If a :count of 0 is specified, it will behave like #assert_no_selector; however, use of that method is preferred over this one.

It also accepts all options that Finders#all accepts, such as :text and :visible.

page.assert_selector('li', :text => 'Horse', :visible => true)

`assert_selector` can also accept XPath expressions generated by the XPath gem:

page.assert_selector(:xpath, XPath.descendant(:p))

Parameters:

  • options (Hash)

    a customizable set of options

Raises:
