Helper to select a Select2 item with Capybara/Cucumber

select2_helper.rb

# spec/support/capybara/select2_helper.rb or features/support/select2_helper.rb

module Select2Helper
  # @example
  #   select2 "Item", from: "select_id"
  #   select2 /^Item/, from: "select_id"
  #
  # @note Works with Select2 version 3.4.1.
  def select2(text, options)
    find("#s2id_#{options[:from]}").click
    all(".select2-result-label").find do |result|
      result.text =~ Regexp.new(text)
    end.click
  end
end

I updated your Gist because it doesn't work if you use the createSearchChoice method in Select2.

module Select2Helper
  def select2(value, attrs)
    first("#s2id_#{attrs[:from]}").click
    find(".select2-input").set(value)
    within ".select2-result" do
      find("span", text: value).click
    end
  end
end

I updated it again for a project im doing.
Hope it provide help or guidance to anybody that needs it.

module Select2Helper
  def select2(value, attrs)
    find("#select2-#{attrs[:from]}-container").click
    find(".select2-search__field").set(value)
    within ".select2-results" do
      find("li", text: value).click
    end
  end
end
World(Select2Helper)

module Select2Helper
  def select2(value, attrs)
    find("#select2-#{attrs[:from]}-container").click

    list = find(:xpath, '//span[@class="select2-results"]', visible: :all)
    list.find("li", text: value).click
  end
end
World(Select2Helper)

I agree with the other posters. I'm using:

find(".select2-result-label", text: Regexp.new(text)).click

One problem is that if the list of options is fetched from a remote source, it won't be loaded immediately. In that scenario, if we use:

all(..).find { |result| result.text ... }

...that means that capybara won't wait for the results to exist, so that block will return nil.

If instead we use:

find(..., text: ...)

...then we're telling Capybara to wait for an element to exist which contains that text, and to fail if it doesn't exist.

This blog post was very helpful in understanding this: https://www.varvet.com/blog/why-wait_until-was-removed-from-capybara/

I wrapped the code which selects options from select2 into a gem capybara-select-2
