Manila tempest tests should be independent from tempest code as much as possible. The decorator test.attr is widely used in all tests to set testcase attrs. This decorator doesn't really do anyting else than calling testtools.testcase.attr. Change-Id: If10beb9ae7562524f602a6fd7254aa95ef24d70e Partially-Implements: bp tempest-no-deps
