TravisTorrent: 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 prominent role in Software Engineering in practice, the benefits, costs,...

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<br/>seek quantifiable evidence on how central testing is to the CI process, how strongly the project language...

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 advice to academic and industrial tool smiths on how to design and build...

When, how, and why developers (do not) test in their IDEs

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 applications, these common expectations and beliefs are rarely ever questioned...

Automatically prioritizing pull requests

In previous work, we observed that in the pull-based development model integrators face challenges with regard to prioritizing work in the face of multiple concurrent pull requests. We present the design and initial implementation of a prototype pull request prioritisation tool called PRioritizer. PRioritizer works like a priority inbox for...

How (Much) Do Developers Test?

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 stands: Is this observation still true? In fact, was it ever true? The...
