Predictive Test Case Selection and Prioritization at Adyen

The set of regression and integration tests at many modern software companies is huge. It is difficult to run all tests after each code change, so the tests are often run for batches of code changes by different developers, late in the release cycle. This has developers waiting for tests longer than desirable and makes it...

Analyzing the Criticality of NPM Packages Through a Time-Dependent Dependency Graph

In (open-source) development, developers routinely rely on other libraries to improve their coding efficiency by reusing code. This reliance on other packages could cause issues when critical dependencies have suddenly have a vulnerability introduced to them. This work analyzes the criticality for NPM. To get an accurate picture of what the most...

Analyzing the effect of introducing time as a component in Python dependency graphs

The use of open-source packages is a common practice among developers. It decreases the development time and improves maintainability. But adding a dependency to a project comes with inherit risks such as introducing vulnerabilities. A few solutions that help visualize all of the dependencies of a project exist already. However, none provide the...

Analyzing the Criticality of Apache Maven Packages Through a Temporal Dependency Graph

Developers rely on different software to improve their efficiency as to reuse parts of code and be able to maintain it with ease, which is why open source software libraries have gained much pop- ularity over the past years. This paper analyzes what are the most used packages from Apache Maven, which is a build automation tool used primarily for...

Using a Time Dependency Graph to find the most widely used Debian package

The main principle of Open Source development is that developers can reuse different libraries over and over again to make their lives easier. That is why this practice has gained a lot of popularity. However, libraries usually depend on other already existing pieces of code. This means that whenever some small piece of code fails, the whole...

Finding most used software application by using a time-dependency graph

Using open-source packages when developing software applications is the general practice among a vast amount of software developers. However, importing open-source code which may depend on other existing technologies may lead to the appearance of a transitive dependency chain. As a result, failure of packages with a high amount of transitive...

A Study of Bugs Found in the Puppet Configuration Management System

This research studies the symptoms, root causes, impact, triggers, fixes, and system dependency of bugs in the Puppet configuration management system. Puppet is a widely used open-source configuration management system that performs various administrative tasks on machines based on a central specification. This paper aims to fill the research...

Studying bugs in the Salt Configuration Management System

Configuration management systems are a class of software used to automate system administrative tasks, one of which is the configuration of software systems. Although the automation is less error-prone than manual configuration done by a human, bugs in the source code can still cause configuration errors. This can result into unwanted...

A Study of Bugs Found in the Moby Configuration Management System

The study of bugs can provide important information to understand their nature in the context of complex software systems as well as supporting developers in their detection, fix and prevention. Previous studies focused on analyzing bugs under different perspectives such as changes at code level, frequency, semantics, symptoms, root causes and...

A study of bugs found in the Ansible configuration management system

Research that focuses on examining software bugs is critical when developing tools for preventing and for fixing software issues. Previous work in this area has explored other types of systems, such as bugs of compilers and security issues stemming from open source systems hosted on public repositories. This paper explores the bugs within the...
