object FakeCameraIds

Utility for tracking and generating fake CameraId instances for testing.

Generated camera IDs are prefixed with "FakeCamera-" to ensure they are non-numerical. This helps identify code that incorrectly assumes camera IDs are parsable as integers (e.g., assuming camera ID "0" can be parsed to 0).

Summary

val default: CameraId

A default fake CameraId instance ("FakeCamera-default").

Use this when a test only needs a single camera ID and uniqueness across different components is not required.
