使用Xamarin.UITest与MvvmCross绑定

Question

I'm using the Xamarin.UITest framework to assert if some button is disabled or enabled. Unfortunately it seems that this is not working if the "Enabled" Property of the button is set via binding trough MVX (binding is working - button is really disabled).

Example axml with two buttons:

    <xxx.Widgets.Button
        android:id="@+id/btnSave"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:text="Save"
        style="@style/DefaultButton"
        local:MvxBind="Click SaveAndContinueCommand; Enabled SaveButtonActive" />
    <xxx.Widgets.Button
        android:id="@+id/btnTest"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:text="Test"
        style="@style/DefaultButton"
        android:enabled="false" />

Query with Xamarin.UITest:

var button = App.Query(v => v.Button("Save")).FirstOrDefault();
Assert.IsFalse(button.Enabled); // -> Button is always enabled

var testButton = App.Query(v => v.Button("Test")).FirstOrDefault();
Assert.IsFalse(button.Enabled); // -> Button is disabled. Correct!

Do I need to pay attention on something different? Has anyone experience with the combination of MVX and Xamarin.UITest?

Answer 1

I don't typically check button properties at the UI test level. I would check that in the core tests where I know that works. With that being said, you could actually tap the button with the UI test and verify that nothing happens if that's possible.

The next thing I would try is fire up your app with Calabash enabled, navigate to this screen and query the buttons to verify you are checking the properties that you should be.
