Quantifying the value of developers’ code contributions to a software project requires more than simply counting lines of code or commits. We define the development value of code as a combination of its structural value (the effect of code reuse) and its non-structural value (the…
Open source software communities are increasingly aware of how social biases and discrimination negatively affect their culture. Many choose to establish policies regulating their contributors' social interactions without considering the efficacy of such measures. If these commun…
In spite of decades of research in bug detection tools, there is a surprising dearth of ground-truth corpora that can be used to evaluate the efficacy of such tools. Recently, systems such as LAVA and EvilCoder have been proposed to automatically inject bugs into software to quic…
Source code clones are categorized into four types of increasing difficulty of detection, ranging from purely textual (Type-1) to purely semantic (Type-4). Most clone detectors reported in the literature work well up to Type-3, which accounts for syntactic differences. In between…
Experimentation aspects (e.g., systematic observation, exploration of alternatives, formulation of hypotheses and empirical testing) can be found dispersed and intertwined in many software systems. Numerous examples are provided in this article. This suggests that experimental ac…
Novel research ideas require strong evaluations. Modern software engineering research evaluation typically requires a set of benchmark programs. Open source software repositories have provided a great opportunity for researchers to find such programs for use in their evaluations.…
Datalog has witnessed promising applications in a variety of domains. We propose a programming-by-example system, ALPS, to synthesize Datalog programs from input-output examples. Scaling synthesis to realistic programs in this manner is challenging due to the rich expressivity of…
Software effort estimation (SEE) usually suffers from data scarcity problem due to the expensive or long process of data collection. As a result, companies usually have limited projects for effort estimation, causing unsatisfactory prediction performance. Few studies have investi…
Automated testing (hereafter referred to as just `testing') has become an essential process for improving the quality of software systems. In fact, testing can help to point out defects and to ensure that production code is robust under many usage conditions. However, writing and…
Software repositories contain historical and valuable information about the overall development of software systems. Mining software repositories (MSR) is nowadays considered one of the most interesting growing fields within software engineering. MSR focuses on extracting and ana…
Web tests are prone to break frequently as the application under test evolves, causing much maintenance effort in practice. To detect the root causes of a test breakage, developers typically inspect the test's interactions with the application through the GUI. Existing automated …
Repairing broken web element locators represents the major main- tenance cost of web test cases. To detect possible repairs, testers typically inspect the tests’ interactions with the application under test through the GUI. Existing automated test repair techniques focus instead …
Reinforcement learning (RL) has seen tremendous success at solving a variety of problems ranging from industrial automation to games. This paper describes how existing programming languages can be augmented with new features so as to allow developers to exploit the power of moder…
Static analysis is a powerful technique to find software bugs. In past years, a few static analysis tools have become available for developers to find certain kinds of bugs in their programs. However, there is no evidence on how effective the tools are in finding bugs in real-wor…
Issue tracking data have been used extensively to aid in predicting or recommending software development practices. Issue attributes typically change over time, but users may use data from a separate time of data collection rather than the time of their application scenarios. We,…
The evolution of software introduces many challenges to its testing. Considerable test maintenance efforts are dedicated to the adaptation of the tests to the changing software. As a result, over time, the test repository may inflate and drift away from an optimal test plan for t…
Open-source projects do not exist in a vacuum. They benefit from reusing other projects and themselves are being reused by others, creating complex networks of interdependencies, i.e., software ecosystems. Therefore, the sustainability of projects comprising ecosystems may no lon…
FinTech, short for ``financial technology,'' has advanced the process of transforming financial business from a traditional manual-process-driven to an automation-driven model by providing various software platforms. However, the current FinTech-industry still heavily depends on …
Developers report testing their regular expressions less than the rest of their code. In this work, we explore how thoroughly tested regular expressions are by examining open source projects.
Alloy is a declarative modeling language that supports first-order logic with transitive closure. Alloy has been used in a variety of domains to model software systems and find design deficiencies. However, it is often challenging to make an Alloy model correct or to debug a faul…
