public final class WindowLayoutInfoPublisherRule implements TestRule

A TestRule to help test consuming a stream of WindowLayoutInfo values. WindowLayoutInfoPublisherRule allows you to push through different WindowLayoutInfo values on demand.

To test the scenario where no WindowLayoutInfo is ever emitted. Just set the rule as a standard rule.

To test sending a generic feature build your own WindowLayoutInfo and publish it through the method WindowLayoutInfoPublisherRule.overrideWindowLayoutInfo.

Some helper methods are provided to test the following scenarios.

• A fold in the middle and the dimension matches the shortest window dimension.
• A fold in the middle and the dimension matches the longest window dimension.
• A fold in the middle and has vertical orientation.
• A fold in the middle and has horizontal orientation.
