# compose

is there a way to turn off animations for a compose hierarchy, for example, in paparazzi snapshots, i want the animation to complete immediately. I can set a property / composition local manually in my composables, but that doesnt seem ideal. 🤔

If you’re talking about setting MotionDurationScale to 0, then yea that’s how to do it. That’s also how the compose animation system handles a11y-disabled animations.

Oh thanks. I couldn’t find in source directly where it is used. Nice!

Thank you

@Zach Klippenstein (he/him) [MOD] do you have any examples of swapping it out?

[agrosner]

it seems its tied to a specific coroutine context

I don’t know how paparazzi initializes compose. It might actually require support from paparazzi, which it can do whenever it’s creating the coroutine context to pass to the recomposer.

But before I assume any more, maybe @Doris Liu knows if there’s already a way to configure this for tests in general?

Paparazzi just creates a compose view and adds it to a framelayout https://github.com/cashapp/paparazzi/blob/b47484676ea53e74d7ef643e385b7b641a5f3e7f/paparazzi/paparazzi/src/main/java/app/cash/paparazzi/Paparazzi.kt#L195

It seems to make sense to allow the MotionDurationScale to be adjusted for test purposes. Please feel to file a feature request for it.

In the meantime, you could set the "animator duration scale" to 0 for your tests via ContentResolver or developer options. The MotionDurationScale is observing that duration scale, so you'll be indirectly changing it. See https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]ondurationScale&ss=androidx%2Fplatform%2Fframeworks%2Fsupport
