#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.

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

Asserts that any 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_any_of_selectors(:custom, 'Tom', 'Joe', visible: all)

#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)

  end
end

#assert_no_selector(*args, &optional_filter_block) ⇒ Object

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

#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(:css, '#my_div', 'a.not_clicked')

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

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))

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_xpath?('.//li', text: 'Horse', visible: true)

has_xpath? can also accept XPath expressions generate by the XPath gem:

xpath = XPath.generate { |x| x.descendant(:p) }
page.has_xpath?(xpath)
