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 {Capybara::Node::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.

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 {Capybara::Node::Finders#all} accepts, such as :text and :visible.

Asserts that a given selector is not on the page or a descendant of the current node. Usage is identical to #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

Asserts that the page or current node doesn't have the given text content, ignoring any HTML tags.

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')

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 {Capybara::Node::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 {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

Asserts that the page or current node has the given text content, ignoring any HTML tags.

Checks if a given CSS selector is on the page or a descendant of the current node.
page.has_css?('p#foo')
By default it will check if the selector occurs at least once, but a different number can be specified.
page.has_css?('p#foo', count: 4)
This will check if the selector occurs exactly 4 times.
It also accepts all options that {Capybara::Node::Finders#all} accepts, such as :text and :visible.

Checks if the page or current node has a form field with the given label, name or id.
For text fields and other textual fields, such as textareas and HTML5 email/url/etc. fields, it's possible to specify a :with option to specify the text the field should contain:
page.has_field?('Name', with: 'Jonas')
It is also possible to filter by the field type attribute:
page.has_field?('Email', type: 'email')
Note: 'textarea' and 'select' are valid type values, matching the associated tag names.

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:

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 {Capybara::Node::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))

Checks if the page or current node has the given text content, ignoring any HTML tags.
Whitespaces are normalized in both node's text and passed text parameter. Note that whitespace isn't normalized in passed regexp as normalizing whitespace in regexp isn't easy and doesn't seem to be worth it.
By default it will check if the text occurs at least once, but a different number can be specified.
page.has_text?('lorem ipsum', between: 2..4)
This will check if the text occurs from 2 to 4 times.

Checks if a given XPath expression is on the page or a descendant of the current node.
page.has_xpath?('.//p[@id="foo"]')
By default it will check if the expression occurs at least once, but a different number can be specified.
page.has_xpath?('.//p[@id="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.has_xpath?('.//li', text: 'Horse', visible: true)
