Method: Capybara::Node::Matchers#has_selector?

Defined in:
lib/capybara/node/matchers.rb

#has_selector?(*args, **options, &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))

  • :maximum (Integer) — default: nil —
