De esta pregunta / respuesta tuve la idea de usar UIAutomator para probar mi aplicación que requiere iniciar sesión en Facebook.

Escribir pruebas para una aplicación de Android que inicia sesión en Facebook

Lo intenté

        UiObject2 editText = mDevice.findObject(By.clazz("android.widget.EditText"));
        editText.setText("[email protected]");

Además de otras cosas, pero haga lo que haga, no puedo hacer que complete el campo. Utilicé la herramienta hierachyviewer para ver que era un EditText. Sin embargo, es una vista web, así que no lo sé.

es posible?

Mi clase de código de prueba completa se adjunta a continuación:

Editar: en realidad usé uiautomatorviewer no hierachyviewer. Aquí hay una captura de pantalla que muestra que es un texto de edición. Al menos según esta herramienta.
