Selenium Conference Austin 2017

We know how complicated it is to have a stable grid, and how hard it is to maintain over time with enough capabilities to cover most browsers and platforms. Internally, we found that ~75% of our tests were executed in Firefox/Chrome, and the remaining were executed in Safari/IE. We decided to develop a tool where docker-selenium nodes are created, used and disposed on demand. For Safari/IE, we just forward the tests to Sauce Labs/BrowserStack. Zalenium is an OSS extension to scale up and down your local grid dynamically with Docker containers. It uses Docker-Selenium to run tests in Firefox/Chrome, and when a different browser is needed, tests get redirected to a cloud testing service. Result: our tests suites run faster since most of the tests run on local Firefox/Chrome nodes, and we use in a smarter way the cloud testing service we pay for.

He will cover continuous delivery, Selenium as a browser automation library, and using Selenium Grid to distribute tests across multiple browser instances. He will then discuss how using Docker containers can help address challenges with scaling tests and reduce costs compared to virtual machines. Manoj will demonstrate how to use the docker-selenium image to run a Selenium Grid hub and nodes within Docker containers.

Using Docker to Develop, Test and Run Maven Projects - Wouter DanesNLJUG

Docker recently hit version 1.0 and is being picked up around the world by Ops teams to ease running their applications. Docker can also play a big role in easing the development of applications. In this talk I will address how to use docker to: - create a more scalable build environment using jenkins and docker; - integration test your software using maven and docker; - package your software and run the images in different environments.

Docker for Integration TestingWouter Danes

The document discusses how Docker can be used for integration testing. It describes how Docker allows running production environments locally, creating proofs of concept, and avoiding port collisions in continuous integration environments. It also outlines how Docker commands like build, run, start, stop, link, expose, and tag can fit into different steps of a build process. Finally, it introduces the docker-maven-plugin for building Docker images and integrating Docker into the Maven build lifecycle for testing.

CI/CD Pipeline with Dockerkushalsingh007

Basic Idea Develop a build system that leverages Docker for implementing continuous integration/deployment(CI/CD) pipeline. A git commit must kick off packaging a Docker Image and provisioning it in a VM. A git based commit should be used for starting of a build for a docker image which would then be run and provisioned in a Virtual Machine. After every commit a series of test cases is then run on the code to ensure the correctness of the code. After all the test-cases pass, the image gets updated on docker-hub registry, and a VM gets provisioned which can then run the software directly (after pulling the image from the docker-hub). This entire process ensures that the most recent and updated version of the code is available to the person who is using the software and this speeds up the overall process by at least 2-3 folds.

Automated-Testing-inside-containersManoj Kumar Kumar

This document discusses test automation using Selenium in a Docker container cluster environment. It begins with an introduction of the speaker and an overview of topics to be covered, including the current technology scenario, Selenium, Selenium Grid, Docker containers, orchestration tools, and recommended third party tools. Key points covered include using Docker containers instead of VMs to run tests in parallel in a lightweight manner, dockerizing tests by building test code into containers, and using orchestration tools like Kubernetes to automate and manage container resources for Selenium Grid. Examples of recommended third party tools that integrate Docker and Selenium are also provided.

Continuous Delivery With Selenium Grid And DockerBarbara Gonzalez

This presentation discusses using Selenium Grid and Docker for continuous delivery and automated testing. It outlines the benefits of continuous delivery such as reduced deployment risk and early bug detection. The presentation then describes using Selenium Grid to run tests across different browsers and machines simultaneously to save time. Docker is discussed as being secure, scalable, and flexible. The solution presented uses Selenium Grid in Docker containers to run a large test suite for multiple products with a small team. Metrics show increased reliability, scheduled test runs, and the ability to write tests in different frameworks. The future plans include moving the grid to an Azure swarm cluster and improving mobile emulation.

Continuous delivery with jenkins, docker and exoscaleJulia Mateo

From Arm to Z: Building, Shipping, and Running a Multi-platform Docker Swarm ...Docker, Inc.

We live in a multi-platform world, and who doesn't want their project to run on all of them? The last few DockerCon events have covered the introduction of multi-platform image capabilities into the Docker registry and engine releases. Now it's time to put these features to good use building applications across architectures and running them all in a heterogeneous Docker Swarm! In this talk we'll cover the new `docker manifest` command for making multi-architecture images; how to emulate architectures in docker containers on your own machine; and give a live demonstration of these capabilities with a Docker Swarm consisting of workers of different CPU architectures, including armhf, ppc64le, s390x, and x86_64. We'll also share some pointers for making sure your project is multi-platform ready! Three Takeaways: 1. Attendees will be introduced to manifest lists and how to create multi-arch images using the new 'docker manifest' command. 2. Attendees will learn how to easily create and deploy a basic multi-arch service using multi-platform images. 3. Bonus: Attendees will learn how to run non-native docker containers on their systems.

Docker for DummiesRoel Hartman

You might (or might not) have heard of Docker. But you have no idea what it is and why you should care. But if you are a database or APEX developer and still work with Virtual Machines, it is about time to broaden your horizon. In this session you'll learn what Docker is and how you can benefit from it in your daily work. In this presentation we will walk through the following subjects: - What is Docker - Where do I get my images - Pull an image - Start a Docker container / Stop / Restart - Use a Docker container for APEX Development : Via the browser, SQL Developer, SQL Plus, etc - Make host directories accessible within the container - Use scripts to modify the image or create your own one

DockerCon EU 2015: Continuous Integration with Jenkins, Docker and ComposeDocker, Inc.

Presented by Sandro Cirulli, Platform Tech Lead, Oxford University Press Oxford University Press (OUP) recently started the Oxford Global Languages (OGL) initiative (http://www.oxforddictionaries.com/words/oxfordlanguages) which aims at providing language resources for digitally under represented languages. In August 2015 OUP launched two African languages websites for Zulu (http://zu.oxforddictionaries.com) and Northern Sotho (http://nso.oxforddictionaries.com). The backend of these websites is based on an API retrieving data in RDF from a triple store and delivering data to the frontend in JSON-LD. The entire micro-service infrastructure for development, staging, and production runs on Docker containers in Amazon EC2 instances. In particular, we use Jenkins to rebuild the Docker image for the API based on a Python Flask application and Docker Compose to orchestrate the containers. A typical CI workflow is as follows: - a developer commits code to the codebase - Jenkins triggers a job to run unit tests - if the unit tests are successful, the Docker image of the Python Flask application is rebuilt and the container is restarted via Docker Compose - if the unit tests or the Docker build failed, the monitor view shows the Jenkins jobs in red and displays the name of the possible culprit who broke the build. A demo of this CI workflow is available at http://www.sandrocirulli.net/continuous-integration-with-jenkins-docker-and-compose

Locally it worked! virtualizing dockerSascha Brinkmann

In normal project work everybody will have heard the sentence: „On my local machine it worked“! The circumstances which lead to this statement are that there are usually minor inconsistencies within the setup of the different environments. Different operating systems, Java versions or installed hot fixes influent the behavior of the developed application and cause issues. This is where Docker comes in place. Docker automates the deployment of applications and isolates them inside software containers, by providing an additional layer of abstraction and automation but with out the overhead caused by a virtual machine. Ones set up, it limits the installation process to 5 minutes independent which environment. Furthermore, the same application can be reused to run on local machines, data centers or in the cloud. We will show you how we incorporated Docker in our continuous deployment process and how we facilitate it for our development and deployment chain.

Desweiteren blicken wir auf den aktuellen Stand der Windows Container in Windows Server 1709 und lernen nützliche Details für den Betrieb eines hybriden Docker Swarm Clusters.

Build Your Own SaaS using DockerJulien Barbier

This document describes how to build a proof of concept Software as a Service (SaaS) using Docker containers. It discusses creating a Docker image with Memcached installed, and using that image to spawn new Memcached containers for each user upon registration on a website. When a user signs up, a new container running Memcached is created for that user using the Docker API. The user is then provided with the IP address and public port of their Memcached container so they can access it.

Easy Setup for Parallel Test Execution with Selenium DockerSargis Sargsyan

Parallel execution of test cases is one of the important requirements of a modern test automation framework. Generally, to run Selenium Suite in parallel, we use selenium grid and distributing tests across multiple machines which will reduce the time required for running tests. To run tests in parallel, we need to configure Selenium Grid with Hub and Nodes where the hub is the central point which will receive test requests along with configurations or capabilities. Based on the request received, the hub will distribute tests to the registered nodes. Selenium has made a set of Docker images which are available on Docker Hub. We have Selenium Grid, and the browser images - Chrome and Firefox. There are also images with the debug versions which will let as view the test execution. In this session, we will go through the Selenium tests parallel run setup and configuration.

Zalenium - Czyli lepszy Selenium GridMichał Ślęzak

Zalenium is an open source Selenium Grid extension that allows for video recording of test runs within a Docker container. It provides features like easy scaling of browser instances using Docker, recording videos of test runs for debugging purposes, and accessing browsers via VNC during tests. Some advantages include support from Zalando, faster performance than traditional Selenium Grid, and open source maintenance. The main disadvantage is that it requires Docker which limits its use on Windows systems initially.

Testing - Selenium? Rich-Clients? Containers?Tobias Schneck

Das Entwickeln und Gestalten von einer UI ist für sich allein genommen bereits eine große Herausforderung. Ganz zu schweigen von der Aufgabe die UI-Tests zu automatisieren. Wurde beides erfolgreich gemeistert, kommen allerdings die nächsten Fragen: * Sollen wir auch die PDF-Auftragsbestätigung im Test validieren? > Natürlich sollten wir! * Ist der Rich-Client auch zu testen? > Ja, wieso denn auch nicht! * Wo sollen die Tests ausgeführt werden? > Natürlich im Docker-Container und im Kubernetes-Cluster! * Können wir die Tests auf ein anderes Framework migrieren? > Was bringt uns das? Wir wollen die bestehenden Tests doch weiterverwenden! Diese Fragen sind den Einen oder Anderen bestimmt nicht neu, aber was tun? Es wurde bereits viel Aufwand und Mühe in die Pflege der umfangreichen Selenium-Testsuiten gesteckt! Daher möchte man diese nur ungern verwerfen, nur um neue Anforderungen umzusetzen. Der Talk zeigt hierfür eine Lösung auf, die mit geringen Aufwand die bestehenden Selenium-Tests einfach erweitert. Die Open-Source-Erweiterung "Sakuli Se" bietet eine umfangreiche API, die es ermöglicht Rich-Clients, PDF-Inhalte oder auch Flash-Anwendungen ebenso leicht wie ein HTML-Button im selben Ausführungskontext zu testen. An Praxisbeispielen wird ebenso demonstriert wie durch vorgefertigte Dockerimages die Testausführung skalierbar bis in Cloud-Umgebung, wie Kubernetes oder OpenShift, aufgebaut werden kann.

ITB2019 Try This At Home: Building a Personal Docker Swarm - Matt ClementeOrtus Solutions, Corp

There’s no shortage of excitement surrounding Docker. But while many developers are familiar with containers in the abstract (they’ve installed Docker on their machines, watched online courses, and played with images locally), they’re unsure of the concrete steps needed to deploy CFML apps to Swarm. Since it’s said that you learn more on your first day of production than all the time beforehand, why wait? In this session, we’ll take a API Mashup project from local development to replicated cloud deployment on a multi-node Swarm. Containerizing a small, fun application provides a great opportunity for acquiring real-world knowledge and hands-on experience. At each step in the process, I’ll share the practical approaches I’ve learned, with the goal of removing obstacles, both real and imagined, that prevent ColdFusion developers from using Swarm.

Topics covered will include: - QA is taboo! (we are now Engineering Productivity – but what does that mean?) – establishing goals as a department goes beyond ensuring quality. How did Blackboard build the teams needed to insure success? - Documentation is like pulling teeth, but so very critical – how the documentation that was created laid the groundwork to improve. She will show examples that have helped teams get on the right track. - Getting the right environment and pieces in place – and slashing execution times (going from our own PD Lab to the world of Mesos). - Project Guardrails. Feature by feature, risk analysis, defining/redistributing/removing tests, and getting developers to trust the tests. Pairing our team with scrum teams fix their tests. It wasn’t all fun and games – what were some of the hiccups that you can learn from Blackboard? Ashley Hunsberger – Test Automation Architect, Blackboard

Embracing Innovation - Using Creativity To Solve Challenging Testing Problems...Selenium Conference Austin 2017

Meredith works on an innovation project at her current company using cutting-edge technology that had many challenges, since the technology has never been tested before. She designed an effective and modular framework using Protractor and mocked the services using TypeScript and Angular2. In this presentation, she will share her experience, provide suggestions, and hopefully inspire people to embrace testing very new and unexplored applications with enthusiasm and confidence. Meredith will also touch a bit on achieving success in this field as a woman and disabled person. It’s all about embracing innovation and believing in yourself!

Embrace Native Async Nature of JavaScript in WebDriver JS - SeleniumConf Aust...Selenium Conference Austin 2017

JavaScript is commonly used for testing due to its asynchronous nature and promise-based libraries that simplify asynchronous code. While JavaScript testing libraries use promises to handle asynchronous code, this can lead to "pyramid of doom" or "callback hell" code structures. New async/await syntax in JavaScript helps address this by allowing asynchronous code to be written in a simpler, synchronous-looking way. Popular JavaScript testing libraries like WebDriverJs support async/await to make asynchronous testing code more readable and maintainable.

Visualize Test Scenarios Using Mind Maps - SeleniumConf Austin 2017Selenium Conference Austin 2017

Gone are the days of writing test scenarios and test cases. There was always a chance of leaving out one tiny but blunderous corner test case. The hassle of creating and maintaining them was something which we had always feared, going through hundreds of links, just to update one piece of functionality. With mind maps, one can better visualise test scenarios, plan out test strategy, provide better coverage, increase understanding of the product, achieve traceability through each component, track data throughout the system, and do a lot more. Using a case study, Ankita will discuss: 1. What are mind maps? 2. How do they serve their purpose in testing? 3. Efficiently creating a mind map for test scenarios 4. Some tools which can be used to create a mind map 5. Converting mind map into test cases into excel sheets or test case management tools. Mind maps not only help in better test cases but in general increase the engineers’ creativity and organisational capability. They are easier to collaborate over with other team members. Being graphical they have better retention and stronger visualisation to estimate and plan better. After all a picture says a thousand words! Ankita Gupta - Software Engineer in Test, Expedia

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik

This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements. Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows. We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure. The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.

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.

Exploring Code Comprehension in Scientific Programming: Preliminary Insight...University of Hawai‘i at Mānoa

This presentation explores code comprehension challenges in scientific programming based on a survey of 57 research scientists. It reveals that 57.9% of scientists have no formal training in writing readable code. Key findings highlight a "documentation paradox" where documentation is both the most common readability practice and the biggest challenge scientists face. The study identifies critical issues with naming conventions and code organization, noting that 100% of scientists agree readable code is essential for reproducible research. The research concludes with four key recommendations: expanding programming education for scientists, conducting targeted research on scientific code quality, developing specialized tools, and establishing clearer documentation guidelines for scientific software. Presented at: The 33rd International Conference on Program Comprehension (ICPC '25) Date of Conference: April 2025 Conference Location: Ottawa, Ontario, Canada Preprint: https://arxiv.org/abs/2501.10037

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.
