    A basic test runner implementation which prints results on standard error.  It
    has a few configurable parameters, but is essentially very simple.  Graphical
    applications which run test suites should provide alternate implementations.

+   special-cased and, when the warning filters are ``'default'`` or ``'always'``,
+   they will appear only once per-module, in order to avoid too many warning

+   :option:`-Wa` options and leaving *warnings* to ``None``.
