Strictly, self.stdout/err is a feature addition; however, it's a feature that is required in order to achieve a massive speedup in the tests and to maintain parity between 1.2.X and trunk tests. However, the feature is completely transparent -- the old technique will work fine, it just isn't as testable. Therefore, we'll treat this as an undocumented feature in the 1.2 branch. git-svn-id: http://code.djangoproject.com/svn/django/branches/releases/1.2.X@13364 bcc190cf-cafb-0310-a4f2-bffc1f526a37
