Composable screenshots with SideEffects

[St4B]

I am not sure whether I use Paparazzi wrongly or if there is a way to achieve the desired behavior, but I think that the API should provide a way to take snapshots after all side effects are executed. For example, I have a composable that renders differently when it has focus. In order to set focus programmatically in our screenshot test, we need to use SideEffect like that:

val focusRequester = remember { FocusRequester() }
MyAwesomeComposable(modifier = Modifier.focusRequester(focusRequester))
SideEffect { focusRequester.requestFocus() }

If I try to take a screenshot while the composable has focus:

paparazzi.snapshot("Awesome composable with focus") {
    val focusRequester = remember { FocusRequester() }
    MyAwesomeComposable(modifier = Modifier.focusRequester(focusRequester))
    SideEffect { focusRequester.requestFocus() }
}

then it seems that the screenshot was taken before the focus was gained (which I think is expected).

Maybe we need something like IdlingResource, or something to force all recompositions to happen.

Can you try this with the latest version 1.3.5. We added the ability to rerender the first frame if a pending recomposition is detected.

Updated to v1.3.5 but it's still not capturing focused state on a button component that's supposed to have an alpha on focus.
