An Introduction To JenkinsKnoldus Inc.

Continuous integrationamscanne

Continuous integration (CI) is a software development practice where developers integrate code into a shared repository frequently, preferably multiple times a day. Each integration is verified by an automated build and test process to detect errors early. CI utilizes source control, automated builds, and tests to minimize the time between code changes being integrated and identified issues being found. While CI focuses on frequent code integration and testing, it does not require constant production releases or infrastructure automation. CI helps reduce integration problems and allows development teams to work together more efficiently.

Introduction to jenkinsAbe Diaz

Jenkins presentationValentin Buryakov

Jenkins is a continuous integration server that detects code changes, runs automated builds and tests, and can deploy code. It supports defining build pipelines as code to make them version controlled and scalable. Popular plugins allow Jenkins pipelines to integrate with tools for testing, reporting, notifications, and deployments. Pipelines can define stages, run steps in parallel, and leverage existing Jenkins functionality.

Continuous Integration for OpenVMS with Jenkinsecubemarketing

Contineous integrationRadhakrishna Mutthoju

This document discusses Continuous Integration (CI), including its definition, workflow, popular tools, requirements, principles, functionalities, and Jenkins configuration. CI is a software development practice where team members frequently integrate their work and have it automatically tested. The workflow involves integrating code changes, building, testing, archiving, and deploying. Popular CI tools include Jenkins, TravisCI, TeamCity, BuildBot, and Bamboo. Jenkins can be installed via packages or by running its WAR file. The advantages of CI include easier configuration, detecting integration issues early, and keeping the codebase bug-free. Initial setup and developing tests can be disadvantages.

From Virtual Machines to Containerscamunda services GmbH

The document discusses Camunda's transition from a traditional Jenkins setup with virtual machines to a containerized continuous integration infrastructure using Docker and Jenkins. Some of the key problems with the previous setup included a lack of isolation between jobs, limited scalability, and difficulties maintaining the infrastructure. The new system achieves isolated and reproducible jobs through one-off Docker containers, scalability through Docker Swarm on commodity hardware, and infrastructure maintenance through immutable Docker images and infrastructure as code definitions. Lessons learned include automating as much as possible, designing for scale, testing all aspects of the new system, and controlling dependencies.

JUC Europe 2015: From Virtual Machines to Containers: Achieving Continuous In...CloudBees

By Christian Lipphardt, Camunda Services Camunda is an open source, Java-based framework process/business process automation. As a middleware technology, Camunda integrates with six different Java application servers (in different versions) and supports six different database products. The team at Camunda maintains five supported versions of Camunda itself, adding two versions every year. Maintaining the necessary continuous integration (CI) infrastructure based on virtual machines became increasingly problematic, with poor build reproducibility and limited scalability. Feedback cycles for developers were unacceptable. Recently Camunda switched from the virtual machine model to a container model based on Docker. The Camunda team now develops infrastructure as code and applies microservice-like separation of concerns. In the talk, Daniel will share the new CI architecture and present lessons learned.

CD with spinnakerAbdulBasit Kabir

Spinnaker is an open source continuous delivery platform started by Netflix that helps release software changes quickly and confidently across multiple clouds including Kubernetes. It provides automated promotion of changes through pipelines that represent the delivery process in a single view along with notifications and triggers. This improves on Jenkins which requires moving changes between jobs manually and lacks a unified view of infrastructure. Setting up Spinnaker involves installing it on a Kubernetes cluster using Helm and exposing the interface. A typical pipeline starts changes in development and promotes them through user acceptance testing to production environments.

Continuous delivery is the process of automating the deployment of code changes to production. It involves building, testing, and deploying code changes through successive environments like integration, testing, and production. Continuous integration starts the process by automatically building and testing code changes. The release pipeline then automates deploying through environments. This finds issues early and allows for rapid deployment of code changes to production through automated testing and infrastructure provisioning.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik

Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe. We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved? Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora

Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora

Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora

Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.
