Class: FakeTicker

Defined in: testing/FakeTicker.ts:17

Minimal drop-in for PIXI.Ticker in tests. Exposes the surface the engine uses (add, remove, deltaMS) plus tick(ms) and tickFor(ms) to advance time by hand, so a whole spin runs in a unit test with no requestAnimationFrame and no wall clock.

const ticker = new FakeTicker();
const wheel = new WheelBuilder().ticker(ticker as unknown as Ticker)...build();
ticker.tickFor(5000); // five seconds, in 16 ms frames
