Allow inheritance of test classes.  For example,

  package Parent;
  use Test2::Tools::xUnit;
  use Test2::V0;

  sub setup : BeforeAll { };
  sub cleanup : AfterAll { };

  sub test0 : Test { };

  package Child;
  use parent Parent;

  sub setup : BeforeAll { };
  sub cleanup : AfterAll { };

  sub test1 : Test { };

  done_testing;

will run

  Parent::setup;
  Child::setup;

  # arbitrary order
  test0;
  test1;

  # yes, this order looks inverted, but that's the order it's run
  Parent::cleanup;
  Child::cleanup;

Parent calss teardown methods are always run before child's, as they are registered
with Test2 first. Conventions can remediate this, for instance,

   package Parent;

   sub AfterAll { } # no attributes!

   package Child;

   use parent 'Parent';

   sub AfterAll :AfterAll {

      # perform Child teardown
      ...

      # move up the inheritance chain
      Child->SUPER::AfterAll;
   }
