Hello,

MVVM ViewModels are Pojos, so they are easy to test... At least, that's half the truth. In reality, ViewModels also contain a lot of annotations (@Command, @GlobalCommand, @NotifyChanges). Of course I can test the pojo, but much of the logic is in the annotations, so while 100% of the pojo may be executed, not nearly 100% of the ViewModel will be tested.

Obviously it would be great to test the ViewModel from the Outside, for example by allowing me to do this..

MyViewModel vm = new MyViewModel();
BindTestUtil.save(vm, "firstName", "Franklin");
BindTestUtil.verifyNotifyChanged(vm, "someProperty");

Is there any way to do this? Preferably without having to simulate ZK's code, since that will only lead to guessing what it might do. ZATS is also overkill for a test like this.... Better ideas, anyone?
