Comment (by SergeyBiryukov):

 In [changeset:"51628" 51628]:
 {{{
 #!CommitTicketReference repository="" revision="51628"
 Tests: Move loading the `PO` class to `set_up_before_class()`.

 This ensures that the class is loaded once before the first test of the
 test case class is run, and `require_once()` is not unnecessarily called
 for each test method individually.

 Follow-up to [1106/tests].

 See #53363.
