/**
   * Setup the environment containing local and remote translation files.
   *
   * Update tests require a simulated environment for local and remote files.
   * Normally remote files are located at a remote server (e.g. ftp.drupal.org).
   * For testing we can not rely on this. A directory in the file system of the
   * test site is designated for remote files and is addressed using an absolute
   * URL. Because Drupal does not allow files with a po extension to be accessed
   * (denied in .htaccess) the translation files get a _po extension. Another
   * directory is designated for local translation files.
   *
   * The environment is set up with the following files. File creation times are
   * set to create different variations in test conditions.
   *   contrib_module_one
   *    - remote file: timestamp new
   *    - local file:  timestamp old
   *    - current:     timestamp medium
   *   contrib_module_two
   *    - remote file: timestamp old
   *    - local file:  timestamp new
   *    - current:     timestamp medium
   *   contrib_module_three
   *    - remote file: timestamp old
   *    - local file:  timestamp old
   *    - current:     timestamp medium
   *   custom_module_one
   *    - local file:  timestamp new
   *    - current:     timestamp medium
   * Time stamp of current translation set by setCurrentTranslations() is always
   * timestamp medium. This makes it easy to predict which translation will be
   * imported.
