#has_css?(path, options = {}) ⇒ Boolean

Checks if a given CSS selector is on the page or 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 Finders#all accepts, such as :text and :visible.

page.has_css?('li', :text => 'Horse', :visible => true)

Parameters:

    Additional options

Options Hash (options):

  • :count (Integer) — default: nil —

Returns:

  • (Boolean) —

#has_selector?(*args) ⇒ Boolean

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

page.has_selector?('p#foo')

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:

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

Parameters:

    Either the kind of selector or the selector itself

  • locator (String) —

end

#has_table?(locator, options = {}) ⇒ Boolean

Checks if the page or current node has a table with the given id or caption.

If the options :rows is given, it will check that the table contains the rows and columns given:

Note that this option is quite strict, the order needs to be correct and the text needs to match exactly.

Parameters:

  • locator (String) —

    The id or caption of a table

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :rows (Array[Array[String]]) —

    A set of rows the table should contain

Returns:

  • (Boolean) —

    Whether it exist
