We present the design of a peer-to-peer (P2P) live streaming system that uses scalable video coding as well as network coding. The proposed design enables flexible customization of video streams to support heterogeneous receivers, highly utilizes upload bandwidth of peers, and quickly adapts to network and peer dynamics. Our design is simple and modular.(More)
CSS is a widely used language for describing the presentation semantics of HTML elements on the web. The language has a number of characteristics, such as inheritance and cascading order, which makes maintaining CSS code a challenging task for web developers. As a result, it is common for unused rules to be accumulated over time. Despite these challenges,(More)
Context: The Web has had a significant impact on all aspects of our society. As our society relies more and more on the Web, the dependability of web applications has become increasingly important. To make these applications more dependable, for the past decade researches have proposed various techniques for testing web-based software applications. Our(More)
—The event-driven and highly dynamic nature of JavaScript, as well as its runtime interaction with the Document Object Model (DOM) make it challenging to test JavaScript-based applications. Current web test automation techniques target the generation of event sequences, but they ignore testing the JavaScript code at the unit level. Further they either(More)
—Web developers often write test cases manually using testing frameworks such as Selenium. Testing JavaScript-based applications is challenging as manually exploring various execution paths of the application is difficult. Also JavaScript's highly dynamic nature as well as its complex interaction with the DOM make it difficult for the tester to achieve high(More)
—Mutation testing is an effective test adequacy assessment technique. However, there is a high computational cost in executing the test suite against a potentially large pool of generated mutants. Moreover, there is much effort involved in filtering out equivalent mutants. Prior work has mainly focused on detecting equivalent mutants after the mutation(More)
Modern web applications rely heavily on JavaScript and client-side runtime manipulation of the DOM (Document Object Model) tree. However, JavaScript is loosely typed, dynamic, and challenging to analyze and test. We propose an automated technique to generate regression test cases at two complementary levels: (1) individual JavaScript functions, and (2) DOM(More)
