From package-based to call-based dependency networks

Modern programming languages such as Java, JavaScript, and Rust encourage software reuse by hosting diverse and fast-growing repositories of highly interdependent packages (i.e., reusable libraries) for their users. The standard way to study the interdependence between softwar ...

Build logs are textual by-products that a software build process creates, often as part of its Continuous Integration (CI) pipeline. Build logs are a paramount source of information for developers when debugging into and understanding a build failure. Recently, attempts to partly ...

Developer Testing in The IDE

Patterns, Beliefs, And Behavior

Software testing is one of the key activities to achieve software quality in practice. Despite its importance, however, we have a remarkable lack of knowledge on how developers test in real-world projects. In this paper, we report on a large-scale field study with 2,443 softwa ...

Blockchain technology has found a great number of applications, from banking to the Internet of Things (IoT). However, it has not yet been envisioned whether and which problems in Software Engineering (SE) Blockchain technology could solve. In this paper, we coin this field 'Bloc ...
Software developers today crave for feedback, be it from their peers in the form of code review, static analysis tools like their compiler, or the local or remote execution of their tests in the Continuous Integration (CI) environment. With the advent of social coding sites such ...
Software developers today crave for feedback, be it from their peers or even bots in the form of code review, static analysis tools like their compiler, or the local or remote execution of their tests in the Continuous Integration (CI) environment. With the advent of social codin ...
Debugging is an inevitable activity in most software projects, often difficult and more time-consuming than expected, giving it the nickname the “dirty little secret of computer science.” Surprisingly, we have little knowledge on how software engineers debug software problems in ...
Micro-clones are tiny duplicated pieces of code; they typically comprise only few statements or lines. In this paper, we study the “Last Line Effect,” the phenomenon that the last line or statement in a micro-clone is much more likely to contain an error than the previous lines o ...
The peer review process is central to the scientific method, the advancement and spread of research, as well as crucial for individual careers. However, the single-blind review mode currently used in most Software Engineering (SE) venues is susceptible to apparent and hidden bias ...

Synthesizing Travis CI and GitHub for Full-Stack Research on Continuous Integration

Continuous Integration (CI) has become a best practice of modern software development. Thanks in part to its tight integration with GitHub, Travis CI has emerged as arguably the most widely used CI platform for Open-Source Software (OSS) development. However, despite its prominen ...

Oops, My Tests Broke the Build

An Explorative Analysis of Travis CI with GitHub

AbContinuous Integration (CI) has become a best practice of modern software development. Yet, at present, we have a shortfall of insight into the testing practices that are common in CI-based software development. In particular, we
seek quantifiable evidence on how central te ...

Warnings From Multiple Automated Static Analysis Tools At A Glance

Automated Static Analysis Tools (ASATs) are an integral part of today’s software quality assurance practices. At present, a plethora of ASATs exist, each with different strengths. However, there is little guidance for developers on which of these ASATs to choose and combine for a ...

Automated test generation tools have been widely investigated with the goal of reducing the cost of testing activities. However, generated tests have been shown not to help developers in detecting and finding more bugs even though they reach higher structural coverage compared ...

How to catch 'em all

WatchDog, a family of IDE plug-ins to assess testing

As software engineering researchers, we are also zealous tool smiths. Building a research prototype is often a daunting task, let alone building an industry-grade family of tools supporting multiple platforms to ensure the generalizability of results. In this paper, we give advic ...
Continuous Delivery is an agile software develop- ment practice in which developers frequently integrate changes into the main development line and produce releases of their software. An automated Continuous Integration infrastructure builds and tests these changes. Claimed advan ...

Analyzing the State of Static Analysis

A Large-Scale Evaluation in Open Source Software

The use of automatic static analysis has been a software engineering best practice for decades. However, we still do not know a lot about its use in real-world software projects: How prevalent is the use of Automated Static Analysis Tools (ASATs) such as FindBugs and JSHint? How ...

The research community in Software Engineering and Software Testing in particular builds many of its contributions on a set of mutually shared expectations. Despite the fact that they form the basis of many publications as well as open-source and commercial testing application ...

What do we know about software testing in the real world? It seems we know from Fred Brooks' seminal work 'The Mythical Man-Month' that 50% of project effort is spent on testing. However, due to the enormous advances in software engineering in the past 40 years, the question s ...

Micro-clones are tiny duplicated pieces of code, they typically comprise only a few statements or lines. In this paper, we expose the "last line effect," the phenomenon that the last line or statement in a micro-clone is much more likely to contain an error than the previous l ...

Code review is the manual assessment of source code by humans, mainly intended to identify defects and quality problems. Modern Code Review (MCR), a lightweight variant of the code inspections investigated since the 1970s, prevails today both in industry and open-source softwa ...
