Getting started

If you're new to this crate, check out the input_playback example to get a good overview of how it all works in practice.

Playback-powered testing

This crate can be used to capture, save to disk, and then play back user inputs in a macro-like fashion. This serialization-based workflow is a natural (if somewhat brittle) fit for testing UI, app logic and gameplay elements of your Bevy apps.

Simply toggle on InputCapturePlugin, set a PlaybackFilePath, perform your inputs and then close the app.

Then, when evaluating tests, loop through each saved input sample, and run your app with the InputPlaybackPlugin, providing a PlaybackFilePath corresponding to the input sample you are testing. AppExit events are also captured, your tests will close down automatically when they're complete.
