The web has had a significant impact on many aspects of our lives and societies. Web applications have become integral parts of our education, entertainment, governments, businesses, and personal and social lives. Rigorous testing is required to ensure all these applications function as expected. However, testing web applications is a particularly challenging endeavour. JavaScript has been the lingua franca of client-side web development. More recently, platforms such as Node.js have made it possible to use JavaScript for writing code that runs outside of the browser on a light-weight, fast, and scalable platform. As such, server-side JavaScript development has also experienced an exponential growth in the past few years. JavaScript owes some of its popularity to the particular set of the language's paradigms, such as asynchronous execution. JavaScript is single-threaded and thus asynchronous callbacks are used regularly to simulate concurrency and provide capabilities such as rich user interactions, non-blocking I/O, and seamless client/server communications. Unfortunately, the analysis and testing techniques have not evolved nearly as much as our programming paradigms in web development have, and are thus not sufficient for detecting and revealing various bugs in asynchronous code. The goal of this research is to facilitate the process of testing asynchronous JavaScript programs in order to allow the development of robust web applications. To this end, we will provide novel techniques and tool support in development environments for JavaScript programmers and testers' everyday testing activities. Our proposed research will examine traditional testing techniques to better understand and address their shortcomings in the presence of new programming paradigms. We propose to revisit testing of asynchronous code, by introducing new paradigms for assessing the adequacy of existing testing techniques for asynchronous JavaScrip execution, generation of tests that address inadequacies of traditional testing for this evolved programming paradigm, and prioritization of the tests. The outcome of this research will have great impact in research and in industry, and will evolve our view of testing asynchronous code.

网络对我们生活和社会的许多方面产生了重大影响。 Web应用程序已成为我们教育，娱乐，政府，企业以及个人和社交生活的组成部分。需要进行严格的测试以确保所有这些应用程序按预期运行。但是，测试Web应用程序是一项特别具有挑战性的努力。 JavaScript一直是客户端Web开发的通用语言。最近，诸如Node.js之类的平台使使用JavaScript进行编写代码成为可能，该代码在浏览器外部以轻质，快速和可扩展的平台在浏览器之外运行。因此，在过去的几年中，服务器端JavaScript开发也经历了指数级的增长。 JavaScript归功于该语言范式的特定集合，例如异步执行。 JavaScript是单线读取的，因此定期使用异步回调来模拟并发性并提供诸如丰富的用户交互，非障碍I/O和无缝客户端/服务器通信等功能。不幸的是，分析和测试技术的发展几乎没有我们在Web开发中的编程范例的发展，因此不足以检测和揭示异步代码中的各种错误。这项研究的目的是促进测试异步JavaScript程序的过程，以允许开发强大的Web应用程序。为此，我们将为JavaScript程序员和测试人员的日常测试活动提供新颖的技术和工具支持。我们拟议的研究将检查传统的测试技术，以更好地理解和解决新编程范式的缺点。我们建议通过引入新的范式来评估异步测试技术的适当性，以重新审视异步代码的测试。这项研究的结果将在研究和行业中产生重大影响，并将发展我们测试异步代码的看法。
