createTestContext

Creates mock PixiJS instances and a context provider. Returns { Provider, ticker, renderer, app }.

Property	Type	Purpose
Provider	Component	Wraps children in mock PixiAppContext, TickerContext, ScreenStoreContext
ticker	ManualTicker	Advance frames with fastForwardFrames() or fastForwardTime()
renderer	TestRenderer	Simulate resize events with emitResize()
app	Pixi.Application	Minimal stub for hooks that call getPixiApp()

Simulating resize

ctx.renderer.emitResize({ width: 1024 });
ctx.renderer.emitResize();
ctx.renderer.emitResize({ width: 1024, height: 768, x: 0, y: 0 });

Spying on mocks

const addSpy = vi.spyOn(ctx.ticker.ticker, "add");
const resizeSpy = vi.spyOn(ctx.renderer, "addListener");

Override defaults

const customTicker = createManualTicker();
vi.spyOn(customTicker.ticker, "add");
const ctx = createTestContext({ ticker: customTicker });
