+### Verify with timeout
+
+This feature is useful when testing asynchronous functionality. You do some action and expect the result to arrive as an asynchronous function call to one of your mocks.
+
+```typescript
+let mockedFoo:Foo = mock(Foo);
+await verify(mockedFoo.getBar(3)).timeout(1000);
+```
+
+
