Cypress Automation

Susantha Pathirana

Cypress is an end-to-end testing framework that focuses on doing testing well through features like time travel debugging, real-time reloads, and automatic waiting. It works on any frontend framework and tests are written in JavaScript alone. Cypress provides an all-in-one solution for developers and QA engineers to set up testing, write Cucumber tests, run and debug tests from a dashboard or command line, and generate reports including screenshots, videos, and JUnit files.

dotnetsheff: Continuous delivery with Team City and Octopus Deploy

Kevin Kuszyk

This document discusses continuous delivery and deployment using Team City and Octopus Deploy. It defines continuous delivery as allowing deployment to production with a single button press through automation. Continuous deployment completely automates putting code changes into production without human intervention. It presents the continuous delivery pipeline of code, build, test, pack, and deploy and shows how Team City and Octopus Deploy can be used together in this process.

Why you should switch to Cypress for modern web testing?

Make It Cooler: Using Decentralized Version Control

indiver

A commonly used version control system in the ColdFusion community is Subversion -- a centralized system that relies on being connected to a central server. The next generation version control systems are “decentralized”, in that version control tasks do not rely on a central server. Decentralized version control systems are more efficient and offer a more practical way of software development. In this session, Indy takes you through the considerations in moving from Subversion to Git, a decentralized version control system. You also get to understand the pros and cons of each and hear of the practical experience of migrating projects to decentralized version control. Version control is often used in conjunction with a testing framework and continuous integration. To complete the picture, Indy walks you through how to integrate Git with a testing framework, MXUnit, and a continuous integration server, Hudson.

Smarter deployments with octopus deploy

Thibaud Gravrand

This document discusses Octopus Deploy, a deployment automation tool. It describes Octopus Deploy's architecture and 7 step deployment process. The process includes declaring environments, creating application packages, defining projects, creating deployment processes with steps and variables, releasing packages, and deploying releases to environments. Octopus Deploy supports features like automated deployments, rollbacks, configuration transformations, and integration with build pipelines. It provides visibility through audit logs and manages deployments across development, test, and production environments.

Practical continuous quality gates for development process

Andrii Soldatenko

There are a lot of books and publications about the continuous integration in the world. But in my experience it’s difficult to find information about how to open quality gates between automated tests and to continuous integration practice to in your current project. After reading several articles and even a couple of books you will understand how to work with it. But what next? I will share with you practical tips and tricks on how to lift iron curtain to your automated tests before a continuous quality practice today. It is for this reason why I am pleased to share with you my acquired experience in my presentation.

Continuous delivery - tools and techniques

Mike McGarr

PyCon Ukraine 2014

Andrii Soldatenko

We live in changeable world, and our applications are also very inconstant. As a result we have to know how to improve project quality. The subject of my presentation is related to the modern approaches of designing and implementing automated functional tests, by using, for instance, design patterns, improving test execution time based parallel execution, scaling by distributing tests on several machines, creating strategy for generation of big sets of test data and setup skeleton for organizing tests for typical Django project. I am pleased to share with you my acquired experience in this field.

e2e testing with cypress

Tomasz Bak

Cypress is an e2e testing tool that allows for testing web applications directly in the browser. It provides native access to the browser without using Selenium, making tasks like taking screenshots and recording videos possible. Some limitations are that it only supports single-page applications and one browser tab at a time. Cypress prioritizes developer experience through features like fast testing, intuitive debugging, and integration with continuous integration systems and dashboards. Many large companies have adopted Cypress for their e2e testing needs.

Continuous Delivery for Front-End Engineers

Sergey Bolshchikov

The document discusses continuous delivery practices for front-end engineers. It outlines seven stages of a continuous delivery process: 1) efficiently reusing code through tools like NPM, Bower, and Yeoman, 2) test-driven development using Karma, Jasmine, Mocha and Protractor, 3) integrating continuously, 4) deploying often through automation to reduce risks, 5) monitoring performance and errors, 6) using feature toggles to deploy unfinished features, and 7) conducting A/B tests to gradually release new features. Moving from traditional waterfall to continuous delivery processes allows deploying from 4 times a year to 50 times a day and building a culture of continuous delivery.

Mukta Aphale

Getting started with Octopus Deploy

Karoline Klever

How do you automate the non-existing deployment routines of an organization with over 100 different customers, each having their own environments? How do you convince the leaders, developers and customers to give you the resources needed in order to automate everything? Is it really possible to introduce a deployment routine that works for everyone? In less than six months, Karoline transformed the deployment routines at Epinova by introducing Octopus Deploy to the organization. She will take you through the steps needed to get started, the pitfalls along the way, and success that Octopus Deploy has become. In this workshop we will start out by installing an Octopus Deploy server and tentacle on your laptop, before looking at the basic concepts of Environments, Machines, Roles and Projects. You will create a project of your own and deploy this using Octopus Deploy before we round off by looking at the advanced topics of Script modules, Step templates, Variable sets and Retention Policies. At the end of this workshop, you'll have all the knowledge you need in order to create a more efficient and failproof deployment process for your project. Keep calm and deploy to production!

Test automation proposal

Mihai-Cristian Fratila

This document proposes an automated test architecture for the UI Builder application using REST API testing, UI testing, and integration testing. It recommends the Rest Assured library for API testing due to its ability to integrate with Jenkins and remove the need for manual HTTP calls. Protractor is proposed for UI testing as it allows testing Angular applications in JavaScript and integrates well with Selenium. Both test frameworks would be set up with their own Git repositories linked to Jenkins jobs. Integration testing would link the API and UI test repos. The test automation aims to provide faster feedback and reduce regressions as the application grows.

Orchestrating Automated Tests in Different Systems - Please Download to watch...

Kelvin Silva

This talk was presented in DevOpsDays Sao Paulo (June/2018) and in Daitan DevWeek (July/2018). What should you do if your product must be tested on multiple operating systems before delivering? And what if it must be tested on different browsers? Now it is a lot of combinations. And how to do this in an agile way? Here is a talk about how we can orchestrate automated tests on different systems, on different browsers. Assuring the coverage on all operating systems and browsers supported by a product is one of the toughest tasks commonly faced when transitioning to a DevOps setup. Due to the high quantity of environment combinations, the complexity of organizing and executing tests increases and can lead to an ineffective pipeline. In this talk, we will evaluate an automated orchestration of complex test suites that delivers the effectiveness needed for proper DevOps.

Software development... for all? (keynote at ICSOFT'2024)

miso_uam

Our world runs on software. It governs all major aspects of our life. It is an enabler for research and innovation, and is critical for business competitivity. Traditional software engineering techniques have achieved high effectiveness, but still may fall short on delivering software at the accelerated pace and with the increasing quality that future scenarios will require. To attack this issue, some software paradigms raise the automation of software development via higher levels of abstraction through domain-specific languages (e.g., in model-driven engineering) and empowering non-professional developers with the possibility to build their own software (e.g., in low-code development approaches). In a software-demanding world, this is an attractive possibility, and perhaps -- paraphrasing Andy Warhol -- "in the future, everyone will be a developer for 15 minutes". However, to make this possible, methods are required to tweak languages to their context of use (crucial given the diversity of backgrounds and purposes), and the assistance to developers throughout the development process (especially critical for non-professionals). In this keynote talk at ICSOFT'2024 I presented enabling techniques for this vision, supporting the creation of families of domain-specific languages, their adaptation to the usage context; and the augmentation of low-code environments with assistants and recommender systems to guide developers (professional or not) in the development process.

Speed up your regression and reduce cost load with Selenoid + K8s + ReportPortal

1. Speed up your regression and reduce cost load with Selenoid + K8s + ReportPortal 1

2. Myroslav Seliverstov Senior Systems Engineer at EPAM, Ukraine Danylo Kuvshynov Senior Software Engineer in Test at EPAM, Ukraine 2

3. Talking about the test infrastructure What we had Steps taken to improve What did we get Existing cons What do we want to get Demo 3

4. 4 • 10 Jenkins jobs (per each banner) • 10 Windows VM’s, each runner has: • Git • Maven • Browsers What we had Infrastructure overview

5. • Full setup for each new host (Java, Maven, Chrome, FF, Opera, etc.) • Maintenance of existing host • Debug of tests 5 What we had Dedicated infrastructure

6. • To many jobs on CI/CD tool • Jobs are tied to workers • Complex config • Artifacts aggregation 6 What we had Complicated CI/CD flow

7. What we had Performance issues • Degradation of tests on long run • Resources are not released on some hosts • JVM/Maven crash • Browser freeze 7

8. What we had Time of regression • As we can’t extend parallels test runs we a locked with time of regression 8

9. Existing solutions Fork Threads Batching 9

10. Steps taken to improve Implementing Selenoid Advantages • Ready containers with browsers • Support of Chrome, FF, Opera • Configurable resource consuming • Video recording, VNC, logs (selenoid-ui) • Quick start on any new project • Load balancing via GGR 10 10

11. 11 Steps taken to improve Kubernetes + Jenkins Kubernetes Master POD1 POD2 POD3

12. Infrastructure overview Jenkins Master 12 Go Grid Router

13. Steps taken to improve Moving Selenoid to Kubernetes • Kubernetes support • Easy to deploy • Resources for each browsers configured separately • No need to install Ggr, Ggr-UI • Free alternative to project Moon 13

14. Infrastructure overview Jenkins Master 14

15. Where is speedup and cost reduce? 15

16. 16 What We Get • Time of regression reduced from 8 hours to 3 • Flaky test count decreased from 25% to 5% • Test infrastructure improved with same amount of money • Stateless runners • Easy maintenance • Easy scalability • Simplification of CI/CD flow • Resources consumption configuration • Selenoid in Kubernetes

17. Existing cons Tight snap to the pipeline which is complicated The difficulty of adaptation for different projects Tie on Jenkins that holds state of tests Inefficiency of using spot instances 17

18. What do we want to get 18 We want not to care about test infrastructure We want not to care about what cloud to use We want not to care about what CI tool to use We want fast tests We want fail tolerance tests We want cost effective infrastructure

19. Skaffold / Helm

20. Report portal • Real-time analytics • Asynchronous real-time reporting • Visualization of auto test results • Machine Learning • REST API • Major test frameworks support 20

21. 21 Infrastructure overview

22. Time for demo 22

23. Questions time 23

24. Useful links 24
