TestKit

Defined in: src/testkit/TestKit.ts:21
Convenience fassade to create an ActorSystem pre-wired for deterministic testing: NoopLogger by default and a TestProbe factory handy.
Typical usage:
const tk = TestKit.create(‘my-spec’); const probe = tk.createTestProbe(); const ref = tk.system.spawn(() => new Worker(probe), ‘worker’); ref.tell(‘go’); await probe.expectMessage(‘done’); await tk.shutdown();
