Common objects for testing
==========================
* :class:`PlatformTest` - used as a decorator, allows running a test function
only on a specific platform (see `plyer.utils.platform`).
* :func:`platform_import` - manual import of a platform specific class instead
of using `plyer.facades.*` proxies.
