Testing toasts#

android.widget.Toast

Warning

Testing toasts is a hard because other toasts can show up and yours will be queued. We hack app with proxy object to mitigate this.

It is also recommended to use snackbar, or your custom way to display brief unintrusive messages instead. So you should consider not testing it at all.

Proxy toast#

Use provided extension methods to be able to spy on showToast functions.

import com.avito.android.util.showToast

showToast("I'am a toast!")

implementation("com.avito.android:proxy-toast:$version")

ToastRule#

@get:Rule
val toastRule = ToastRule()

fun test() {
    toastRule.checks.toastDisplayedWithText("I'am a toast!")
}

androidTestImplementation("com.avito.android:toast-rule:$version")
