Does Behaviour Driven Development work? Unfortunately, it usually does not. While many people try to pitch as a way to bridge the gap between stakeholders on the project, many teams fail to communicate their test scenarios with everyone involved. Although this fundamental problem of lack of communication can be solved on the organization level, BDD is often used with Cucumber or Robot frameworks. Due to the complexities of these tools, developers and testers stop seeing the benefit in the entire approach of BDD and abundant the practice. However, recently, Behavior Driven Development has seen a resurgence in adoption, thanks to Gauge framework. With the latest release of Taiko, they create a great combination of communication and testing tool with the use of Gauge+Taiko. In this talk, we will discuss BDD principles and how Gauge can be used to take Behavior Driven Development to the next level. With Taiko, the audience will learn how BDD can be taken to the web in a few easy steps and to see what needs to be avoided when these tools are implemented in any organization.

Behaviour Driven Development (BDD) and Domain Driven Design (DDD) seen a great growth in adoption in recent years. We are all creating new practices and tools that try and bring these two very important modern methodologies together. What if we have it backwards and they were actually together all along? What if most of the misunderstandings and challenges we face in implementing BDD are spawned from the very simple mistake of us separating something that was created as a whole? In this talk we'll delve into BDD as it was meant to be done from the beginning and look at its very rooted connection with the software design.

NGINX, Istio, and the Move to Microservices and Service Mesh

NGINX, Inc.

On-demand recording: https://www.nginx.com/resources/webinars/istio-move-to-microservices-service-mesh/ About the webinar NGINX is widely known, used, and trusted for a variety of purposes. NGINX works as a reliable, high-performance web server, reverse proxy server, and load balancer. NGINX is also a widely used microservices hub, an Ingress controller for Kubernetes, and a sidecar proxy in the Istio service mesh. In this webinar, we’ll describe the move to microservices, the crucial role that NGINX has already played, and a range of architectural options that organizations have for their microservices apps, including three progressively complex models in the NGINX Microservices Reference Architecture. We’ll then introduce the emergence of Kubernetes as a container orchestration framework, the use of service mesh architectures, and the design of Istio. We’ll finish by showing how NGINX Open Source and NGINX Plus can be used as the sidecar proxy in an Istio service mesh, bringing greater reliability and capability to your service mesh application.

This presentation about Selenium WebDriver will help you understand what is Selenium, why Selenium WebDriver was developed, what exactly is Selenium WebDriver, the architecture of Selenium WebDriver and the limitations of Selenium WebDriver. In the end, we'll be looking at a demo showing the working of WebDriver using java. Selenium is an automated testing tool that tests web applications across various platforms and browsers. WebDriver happens to be one of the Selenium tools with a simple yet robust architecture. It controls the browser based on the user program. WebDriver revolutionized automation testing and continues to do so. Let's move further and understand the selenium web driver in detail. Below are the topics we will be discussing in the presentation: 1. What is Selenium? 2. Why Selenium WebDriver? 3. What is Selenium WebDriver? 4. The architecture of Selenium WebDriver 5. Limitations of Selenium WebDriver 6. Demo: Automation testing with WebDriver Selenium training has been designed to help developers and manual testers learn how to automate web applications with a robust framework, and integrate it within the DevOps processes of an organization. The course includes basic as well as advanced concepts of WebDriver and other tools/frameworks like TestNG, Maven, AutoIT, Sikuli, log4j. Special focus is given on building a robust framework with Page Object Design Pattern, Data-Driven Approach, and creating reusable components to improve productivity. The course also covers the Selenium Grid, which along with TestNG helps achieve parallel execution to improve coverage and reduce execution time for faster feedback. Appium is an open source test automation framework for use with native, hybrid, and mobile web applications. The course includes a project where you have to create the test automation for an eCommerce application with a framework and reporting. What are the objectives of this Selenium training course? This course will enable you to: 1. Revise the core Java concepts which are essential for learning Selenium WebDriver 2. Understand the scope of Test Automation in DevOps and fundamentals of Test Automation 3. Create Test Cases using Selenium IDE – Record and Playback tool 4. Understand Selenium WebDriver architecture and various layers of interaction 5. Set up WebDriver project in Eclipse and write test cases using TestNG 6. Locate elements using various locating techniques 7. Work with various WebDriver commands to drive web browser and various WebElement commands to deal with various web components 8. Learn to deal with various possible scenarios in terms of pop-ups, multiple Windows, frames, taking screenshots 9. Implement Page Object Design Pattern and Data Driven Testing 10. Understand how to use Maven, ANT, AutoIT, Sikuli, log4j, and listeners 11. Learn to use Selenium Grid with TestNG for parallel execution Learn more at https://www.simplilearn.com/selenium-certification-training

Continuous delivery-with-maven

John Ferguson Smart Limited

Maven is close to ubiquitous in the world of enterprise Java, and the Maven dependency ecosystem is the de facto industry standard. However, the traditional Maven build and release strategy, based on snapshot versions and carefully planned releases, is difficult to reconcile with modern continuous delivery practices, where any commit that passes a series of quality-control gateways can qualify as a release. How can teams using the standard Maven release process still leverage the benefits of continuous delivery? This presentation discusses strategies that can be used to implement continuous delivery solutions with Maven and demonstrates one such strategy using Maven, Jenkins, and Git.
