end

#assert_all_of_selectors([kind = Capybara.default_selector], *locators, **options) ⇒ Object

Asserts that all of the provided selectors are present on the given page or descendants of the current node. If options are provided, the assertion will check that each locator is present with those options as well (other than :wait).

page.assert_all_of_selectors(:custom, 'Tom', 'Joe', visible: all)
page.assert_all_of_selectors(:css, '#my_div', 'a.not_clicked')

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

The :wait option applies to all of the selectors as a group, so all of the locators must be present within :wait (Defaults to Capybara.default_max_wait_time) seconds.

def assert_all_of_selectors(*args, wait: nil, **options, &optional_filter_block)
  wait = session_options.default_max_wait_time if wait.nil?
  selector = extract_selector(args)
  synchronize(wait) do
    args.each do |locator|
      assert_selector(selector, locator, options, &optional_filter_block)
    end
  end
end

#assert_matches_selector(*args, &optional_filter_block) ⇒ Object

Asserts that the current_node matches a given selector

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

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

node.assert_matches_selector('li', text: 'Horse', visible: true)

Parameters:

  • kind (Symbol) —

    Optional selector type (:css, :xpath, :field, etc.) - Defaults to Capybara.default_selector

  • locator (String) —

    The locator for the specified selector

  • options (Hash) —

    a customizable set of options

Raises:

    raise Capybara::ExpectationNotMet, "Item does not match the provided selector" unless result.include? self
  end
end

#assert_no_selector(*args, &optional_filter_block) ⇒ Object Also known as: refute_selector

Asserts that a given selector is not on the page or a descendant of the 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:

#assert_no_text(type, text, **options) ⇒ true #assert_no_text(text, **options) ⇒ true

    Parameters:

    • type (:all, :visible) —

    • text (String, Regexp) —

      The string/regexp to check for. If it’s a string, text is expected to include it. If it’s a regexp, text is expected to match it.

  • #assert_no_text(text, **options) ⇒ true

    Parameters:

    • text (String, Regexp) —

      The string/regexp to check for. If it’s a string, text is expected to include it. If it’s a regexp, text is expected to match it.

#assert_none_of_selectors([kind = Capybara.default_selector], *locators, **options) ⇒ Object

Asserts that none of the provided selectors are present on the given page or descendants of the current node. If options are provided, the assertion will check that each locator is present with those options as well (other than :wait).

page.assert_none_of_selectors(:custom, 'Tom', 'Joe', visible: all)
page.assert_none_of_selectors(:css, '#my_div', 'a.not_clicked')

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

The :wait option applies to all of the selectors as a group, so none of the locators must be present within :wait (Defaults to Capybara.default_max_wait_time) seconds.

end

#assert_selector(*args, &optional_filter_block) ⇒ Object

Asserts that a given selector is on the page or a descendant of the 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:

  • kind (Symbol) —

    Optional selector type (:css, :xpath, :field, etc.) - Defaults to Capybara.default_selector

  • locator (String) —

    The locator for the specified selector

  • options (Hash) —

#has_select?(locator = nil, **options, &optional_filter_block) ⇒ Boolean

Checks if the page or current node has a select field with the given label, name or id.

It can be specified which option should currently be selected:

page.has_select?('Language', selected: 'German')

For multiple select boxes, several options may be specified:

page.has_select?('Language', selected: ['English', 'German'])

It’s also possible to check if the exact set of options exists for this select box:

page.has_select?('Language', options: ['English', 'German', 'Spanish'])

You can also check for a partial set of options:

page.has_select?('Language', with_options: ['English', 'German'])

Parameters:

  • locator (String) (defaults to: nil) —

    The label, name or id of a select box

  • options (Hash) —

    a customizable set of options

Options Hash (**options):

  • :options (Array) —

    Options which should be contained in this select box

  • :with_options (Array) —

    Partial set of options which should be contained in this select box

  • :selected (String, Array) —

    Options which should be selected

  • :with_selected (String, Array) —

    Partial set of options which should minimally be selected

Returns:

  • (Boolean) —

    Whether it exists

end

#has_selector?(*args, &optional_filter_block) ⇒ Boolean

Checks if a given selector is on the page or a descendant of the current node.

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

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

page.has_selector?('p.foo', count: 4)

This will check if the expression occurs exactly 4 times.

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

page.has_selector?('li', text: 'Horse', visible: true)

has_selector? can also accept XPath expressions generated by the XPath gem:

page.has_selector?(:xpath, XPath.descendant(:p))

Parameters:

  • args
  • kind (Symbol) —

    Optional selector type (:css, :xpath, :field, etc.) - Defaults to Capybara.default_selector

  • locator (String) —

    The locator for the specified selector

  • options (Hash) —

    a customizable set of options

Options Hash (*args):

  • :count (Integer) — default: nil —

    Number of times the text should occur

  • :minimum (Integer) — default: nil —

    Minimum number of times the text should occur

  • :maximum (Integer) — default: nil —

    Maximum number of times the text should occur

  • :between (Range) — default: nil —

    Range of times that should contain number of times text occurs

Returns:

  • (Boolean) —

    If the expression exists

#has_text?(type, text, **options) ⇒ Boolean #has_text?(text, **options) ⇒ Boolean Also known as: has_content?

Checks if the page or current node has the given text content, ignoring any HTML tags.
