end
assert_no_selector(*args) click to toggle source

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

@param (see Capybara::Node::Finders#assert_selector) @raise [Capybara::ExpectationNotMet] If the selector exists

# File lib/capybara/node/matchers.rb, line 99
def assert_no_selector(*args)
  synchronize do
    result = all(*args)
    result.matches_count? and raise Capybara::ExpectationNotMet, result.negative_failure_message
  end
  return true
end
assert_selector(*args) click to toggle source

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.

It also accepts all options that {Capybara::Node::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))

@param (see Capybara::Node::Finders#all) @option options [Integer] :count (nil) Number of times the expression should occur @raise [Capybara::ExpectationNotMet] If the selector does not exist

# File lib/capybara/node/matchers.rb, line 83
def assert_selector(*args)
  synchronize do
    result = all(*args)
    result.matches_count? or raise Capybara::ExpectationNotMet, result.failure_message
  end
  return true
end
