Creating Mock Resources

Code

var windowImplProvider = Substitute.For<IWindowImplProvider>(); // (1)!
var window = MockResourceFactory.Create(new ResourceHandle<Window>((nuint) 123UL), windowImplProvider);

window.Size = new XYPair<int>(100, 200); // (2)!
windowImplProvider.Received(1).SetSize(new ResourceHandle<Window>((nuint) 123UL), new XYPair<int>(100, 200));

1. This example demonstrates creating a mock implementation for Windows using NSubstitute, but you can use your preferred mocking library of choice.
2. This line sets the size of the mock Window to 100x200. The line below uses NSubstitute to check that the call was received on the mock IWindowImplProvider.

Explanation

You can create mock resources with MockResourceFactory.Create().

Every resource type in TinyFFR is constructed of a ResourceHandle<T> (where T is the resource type, e.g. Window) and an [...]ImplProvider interface (e.g. IWindowImplProvider).

The example above shows a simple demonstration of constructing a Window with a mock IWindowImplProvider; you can then use the mocked-out implementation to override the behaviour of the Window.

The ResourceHandle<T> can have any value set; note that resources with the same implementation reference and same handle integer value are considered equal.
