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.
