Public Class Methods

HTML(html) click to toggle source

Parse raw html into a document using Nokogiri, and adjust textarea contents as defined by the spec.

@param [String] html The raw html @return [Nokogiri::HTML::Document] ::HTML document

# File lib/capybara.rb, line 289
def HTML(html)
  Nokogiri::HTML(html).tap do |document|
    document.xpath('//textarea').each do |textarea|
      textarea.content=textarea.content.sub(/\A\n/,'')
    end
  end
end
add_selector(name, &block) click to toggle source

Add a new selector to Capybara. Selectors can be used by various methods in Capybara to find certain elements on the page in a more convenient way. For example adding a selector to find certain table rows might look like this:

Capybara.add_selector(:row) do
  xpath { |num| ".//tbody/tr[#{num}]" }
end

This makes it possible to use this selector in a variety of ways:

find(:row, 3)
page.find('table#myTable').find(:row, 3).text
page.find('table#myTable').has_selector?(:row, 3)
within(:row, 3) { expect(page).to have_content('$100.000') }

Here is another example:

Capybara.add_selector(:id) do
  xpath { |id| XPath.descendant[XPath.attr(:id) == id.to_s] }
end

Note that this particular selector already ships with Capybara.

@param [Symbol] name The name of the selector to add @yield A block executed in the context of the new {Capybara::Selector}

# File lib/capybara.rb, line 106
def add_selector(name, &block)
  Capybara::Selector.add(name, &block)
end
configure() { |self| ... } click to toggle source

Configure Capybara to suit your needs.

node = Capybara.string <<-HTML
  <ul>
    <li id="home">Home</li>
    <li id="projects">Projects</li>
  </ul>
HTML

node.find('#projects').text # => 'Projects'
