Ruby Training in Cologne

In this instructor-led, live training in Cologne participants combine the power of Ruby with Selenium to automate the testing of a sample web application. By learning to create and combine Ruby test scripts with Selenium web automation in a live lab environment, participants will gain the knowledge and practice needed to automate the testing of their own real life web applications and websites.

Programming in Ruby involves working with a dynamic, flexible scripting language that has many distinctive features. Here are some key aspects of Ruby programming: Ruby strives to be readable and concise, allowing you to write code that is close to natural language. Ruby is a dynamic language, which means that variable types are determined automatically as the code executes. In Ruby, everything is an object, which makes object-oriented programming the main paradigm of the language. All values, including numbers and functions, are objects. Ruby offers blocks of code that can be passed as arguments to functions. This allows you to create iterators and conveniently operate on data collections. Ruby has rich standard libraries that make it easier to work with various tasks such as text manipulation, networking, data parsing, etc. Ruby is often used in creating web applications thanks to popular frameworks such as Ruby on Rails, Sinatra and Padrino, which offer tools for rapid creation of web applications. There are many testing tools in Ruby, which favors the practice of Test Driven Development (TDD) and Behavior Driven Development (BDD). Ruby supports the implementation of various design patterns, which allows you to create flexible and scalable applications. Ruby is appreciated by developers for its readability, flexibility and intuitive syntax. It allows you to create elegant and readable code, which is one of its main advantages. Ruby programming is often chosen for creating web applications, automation tools, data analysis and many other applications due to its efficiency and flexibility.

Ruby on Rails (RoR) is an open-source server-side web application framework based on the Ruby programming language and the Rails software library. It is a model-view-controller (MVC) framework that provides default structures for a database, a web service, and web pages. In this instructor-led, live training, participants will learn the fundamentals of web development with Ruby on Rails as they build various web applications based on real-world use cases. By the end of this training, participants will be able to:

• Understand the fundamentals of Ruby on Rails programming
• Implement basic and advanced web app features using Ruby on Rails
• Build a functional web application using Ruby on Rails

Audience

• Developers

Format of the course

• Part lecture, part discussion, exercises and heavy hands-on practice

This one-day course walks participants through the fundamentals of RSpec, BDD (Behavior Driven Development) and other testing methods with hands-on exercises.

Watir (Web Application Testing in Ruby) is an open source library for automating tests. Watir interacts with a browser the same way people do: clicking links, filling out forms and validating text. Based on the WebDriver framework, it is comparable to Selenium and is one of the most popular tools for web application test automation. In this training participants will learn how to use Watir to automate their web application testing by combining theory with practice in a live lab environment. By the end of the course, participants will have the knowledge and practice to utilize the full power of Watir and Ruby to automate their web testing projects.

Format of the Course

• An instructor-led course with theoretical coverage of Watir and Ruby together with exercises and a large component of hands-on practice.
