Feature: Update existing PO files from a POT file

  Background:
    Given an empty directory

  Scenario: Bail for invalid source file
    When I try `wp i18n update-po bar/baz.pot`
    Then STDERR should contain:
      """
      Error: Source file does not exist!
      """
    And the return code should be 1

  Scenario: Does nothing if there are no PO files
    Given an empty foo-plugin directory
    And a foo-plugin/foo-plugin.pot file:
