Fixing time zone issue in specs between 0:00 and 2:00

README.md

Some of our specs failed between 0:00 and 2:00, but succeeded otherwise.

The issue had been that to_date itself does not consider the timezone, such that we had to replace expressions like

I18n.localize @some_datetime.to_date

with

I18n.localize @some_datetime.in_time_zone(TEST_TIMEZONE).to_date

in order to have the specs succeed at any time.

some_spec.rb

require 'spec_helper'

describe "something that depends on localized dates" do
  # ...
  
      it 'should be possible to change the date' do
        within('#corporate_vita') do

          @valid_from_formatted = I18n.localize @membership.valid_from.in_time_zone(TEST_TIMEZONE).to_date
          page.should have_content @valid_from_formatted

          @new_date = 10.days.ago.in_time_zone(TEST_TIMEZONE).to_date
          fill_in "valid_from_localized_date", with: I18n.localize(@new_date)
          
          page.should have_no_selector("input")
          page.should have_content I18n.localize(@new_date)
          
        end
      end

end

spec_helper.rb

I18n.default_locale = :de
I18n.locale = :de
TEST_TIMEZONE = "Berlin"
