# Testing Cast Applications

> [!CAUTION]
> **Caution:** These test cases continuously evolve. Make sure you are using the most recent version. We suggest making a new copy before running your test cycle.

Developers are responsible for testing their applications and ensuring users
have a positive and consistent Cast experience, as well as for Cast Connect on
ATV devices. Please run the below test cases on your app across all platforms.

Take note of the test priority. P0 is the highest priority and your application
must not launch with a P0 bug.

Testing is currently manual. Test cases test all aspects of your Cast
application: the sender, Web Receiver, multi-sender scenario, playback, autoplay
(when applicable), queueing (when applicable), voice control, and experiences on
smart displays.
