Class ThreadlessNotificationTestHelper

java.lang.Object

de.saxsys.mvvmfx.utils.notifications.ThreadlessNotificationTestHelper

All Implemented Interfaces:

NotificationObserver

public class ThreadlessNotificationTestHelper
extends Object
implements NotificationObserver

The ThreadlessNotificationTestHelper is an alternative to the NotificationTestHelper and can be used to test notifications, for instance from view models. Unlike the NotificationTestHelper, this class does not use a thread and does also not rely on the JavaFX runtime environment being started. This makes this class useful in unit tests within test environments where JavaFX can not be used.

This class implements NotificationObserver, which means that it can be added as subscriber. It records every received notification and can be queried afterwards.
