Starting with Android Espresso libs 3.6.0 the captureToBitmap was changed
Previous with 3.5.x:
fun ViewInteraction.captureToBitmap(): Bitmap {
using it
onView(isRoot()).captureToBitmap().writeToTestStorage("${javaClass.simpleName}_${nameRule.methodName}-open")
Now in 3.6.x
I only found
class CaptureToBitmapAction(val bitmapReceiver: ViewActions.BitmapReceiver) : ViewAction {
So I tried
class BitmapReceiver(name: String) : ViewActions.BitmapReceiver {
override fun onBitmapCaptured(bitmap: Bitmap?) {
TODO("Not yet implemented")
}
}
val receiver = BitmapReceiver("${javaClass.simpleName}_${nameRule.methodName}-open")
onView(isRoot()).perform(CaptureToBitmapAction(receiver))
But I don’t know what to do in onBitmapCaptured
The question is now, how to do an Espresso test screenshot with 3.6.x ?
I made it work with
import android.graphics.Bitmap
import androidx.test.core.graphics.writeToTestStorage
import androidx.test.espresso.action.ViewActions
class BitmapReceiver(val name: String) : ViewActions.BitmapReceiver {
override fun onBitmapCaptured(bitmap: Bitmap?) {
bitmap?.writeToTestStorage(name)
}
}
using it
val receiver = BitmapReceiver("${javaClass.simpleName}_${nameRule.methodName}-open")
onView(isRoot()).perform(CaptureToBitmapAction(receiver))
