        paparazzi.snapshot(root)

It’s possible to use the snapshot method for composables from Paparazzi to easily wrap the ConstraintLayout view under test into a column so the height is not the device height anymore. Like:

fun method() {
  val yourView = paparazzi.inflate<ConstraintLayout>(R.layout.your_view)
  paparazzi.snapshot {
    Column {
      AndroidView(modifier = Modifier.fillMaxWidth(), factory = {
        yourView
      })
    }
  }
}

But the margins of the ConstraintLayout are gone 😦

It’s now working, but margins around the view are not there:
