 `assert.async()` returns a callback function and pauses test processing until the callback function is called. The callback will throw an `Error` if it is invoked more often than the required call count.
 
+Since [QUnit 1.16][], it is usually better to write asynchronous tests as [async functions][]. This ensures that tests fail early, rather than timing out, if an exception causes the `done` callback to not be called.

 ### Wait for multiple callbacks
 
 Call `assert.async()` multiple times to wait for multiple async operations. Each `done` callback must be called exactly once for the test to pass.
