<ul><li>To test CompletableFuture.runAsync() method, one can use Awaitility library.</li><li>The traditional approach of using Thread.sleep(...) to wait for asynchronous processing is inefficient.</li><li>By adding the Awaitility library as a dependency, test assertions can be wrapped with the await method.</li><li>The Awaitility library repeatedly evaluates the assertions until they are successful, ensuring completion of asynchronous processing before verification.</li></ul>
