RSpec + Capybara— testing date_picker

author @no___tea/

I use bootstrap-datepicker for years because it’s easy to integrate to my favorite simple_form.

Here is some code of my module, which I use to test date_picker inputs.

# frozen_string_literal: true
module DatePickerHelper
  def click_on_date_picker_date(input_name, value:)
    find("input[name='#{input_name}']").click
    value_time = value.to_datetime.to_time
    move_to_needed_month value_time
    find('td.day:not(.old):not(.new)', exact_text: value.split('.').first.to_i.to_s).click
  end
private
  def move_to_needed_month(value_time)
    difference = TimeDifference.between(value_time, Time.now).in_months
    difference = DateTime.now.day < 15 ? difference.round.floor : difference.floor
    if value_time > Time.now
      difference.times { find('th.next').click }
    elsif value_time < Time.now
      difference.times { find('th.prev').click }
    end
  end
end

Params:

• input_name — name an attribute of date_picker in HTML code;
• value — date, you want to set in this input (in this case we expecting value in Russian %d.%m.%Y , but I’m sure that this module can be used for many formats);

What does it do?

• Click the input to open date_picker;
• click on << or >> to get needed month and year
• finding needed day in the month and click on it

Please, use it or share your own way to test date_pickers.
