Performance problems pose a significant risk to software vendors. If left undetected, they can lead to lost customers, increased operational costs, and damaged reputation. Despite all efforts, software engineers cannot fully prevent performance problems being introduced into an a…
In many critical systems domains, test suite adequacy is currently measured using structural coverage metrics over the source code. Of particular interest is the modified condition/decision coverage (MC/DC) criterion required for, e.g., critical avionics systems. In previous inve…
Many software maintenance tasks require locating code units that implement a certain feature (termed as feature location). Feature location has been an active research area for more than two decades. However, there is lack of publicly available, large scale benchmarks for e valua…
Code smells are indicators of issues with source code quality that may hinder evolution. While previous studies mainly focused on the effects of individual code smells on maintainability, we conjecture that not only the individual code smells but also the interactions between cod…
This tool paper presents a tool for performing memoized symbolic execution (Memoise), an approach we developed in previous work for more efficient application of symbolic execution. The key idea in Memoise is to allow re-use of symbolic execution results across different runs of …
Modern computer systems are prone to various classes of runtime faults due to their reliance on features such as concurrency and peripheral devices such as sensors. Testing remains a common method for uncovering faults in these systems. However, commonly used testing techniques t…
Efficient bug triaging procedures are an important precondition for successful collaborative software engineering projects. Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contri…
There are hundreds of general contests targeting undergraduate and graduate students. The prizes vary from cash, trip, fame, conference participation and others. Contests could be class, school, national, regional or global contests. In this paper, we compare between existing stu…
We present a technique that simplifies tests at the semantic level. We first formalize the semantic test simplification problem, and prove it is NP-hard. Then, we propose a heuristic algorithm, SimpleTest, that automatically transforms a test into a simpler test, while still pres…
This paper presents ConfDiagnoser, an automated configuration error diagnosis tool for Java software. Conf-Diagnoser identifies the root cause of a configuration error - a single configuration option that can be changed to produce desired behavior. It uses static analysis, dynami…
The behavior of a software system often depends on how that system is configured. Small configuration errors can lead to hard-to-diagnose undesired behaviors. We present a technique (and its tool implementation, called ConfDiagnoser) to identify the root cause of a configuration …
For a large and evolving software system, the project team could receive many bug reports over a long period of time. It is important to achieve a quantitative understanding of bug-fixing time. The ability to predict bug-fixing time can help a project team better estimate softwar…
In recent years, researchers have intensively investigated various topics in test-case prioritization, which aims to re-order test cases to increase the rate of fault detection during regression testing. The total and additional prioritization strategies, which prioritize based o…
A huge wealth of various data exist in the practice of software development. Further rich data are produced by modern software and services in operation, many of which tend to be data-driven and/or data-producing in nature. Hidden in the data is information about the quality of s…
Producing industrial impact has often been one of the important goals of academic or industrial researchers when conducting research. However, it is generally challenging to transfer research results into industrial practices. There are some common challenges faced when pursuing …
Remote code execution (RCE) attacks are one of the most prominent security threats for web applications. It is a special kind of cross-site-scripting (XSS) attack that allows client inputs to be stored and executed as server side scripts. RCE attacks often require coordination of…
This paper is a report on The 8th IEEE/ACM International Workshop on Automation of Software Test (AST 2013) at the 35th International Conference on Software Engineering (ICSE 2013). It sets a special theme on testing-as-a-service (TaaS). Keynote speech and charette discussions ar…
Client-side computation in web applications is becoming increasingly common due to the popularity of powerful client-side programming languages such as JavaScript. Clientside computation is commonly used to improve an application's responsiveness by validating user inputs before …
Missing requirements are known to be among the major causes of software failure. They often result from a natural inclination to conceive over-ideal systems where the software-to-be and its environment always behave as expected. Obstacle analysis is a goal-anchored form of risk a…
The uniqueness (or otherwise) of test outputs ought to have a bearing on test effectiveness, yet it has not previously been studied. In this paper we introduce a novel test suite adequacy criterion based on output uniqueness. We propose 4 definitions of output uniqueness with var…
