Selenium WebDriver has grown to become the default choice for browser automation for most test engineers either directly or as the underlying engine in many tools. Selenium provides building blocks for browser automation. Direct test automation code of professional quality needs a lot of thought and verbose code if directly written with Selenium. On top of this, any web UI test automation framework in a team grows over time to encapsulate test engine needs. Practical observation is that any mature web test automation framework has possibly 10-15% Selenium related code and rest is about reading of files, hooks, configuration handling, business functions, and so on. On the same lines, Page Object Model in its original form turns out to be too basic for professional usage needs.

This presentation discusses the advanced Gui Abstraction Model supported by Arjuna for Web UI Automation. It is a step by step presentation where Rahul takes raw Selenium code and discusses specific problems/challenges (Python is used as the code medium as the framework is in Python as well). Then step by step he takes it through transitioning while using Arjuna facilities.

Arjuna is a Python-based test automation framework developed by Rahul Verma. It is an open-source, Apache Licensed software. Rahul has implemented smaller variants of features in Arjuna across frameworks and organizations or given advice around it. However, Arjuna being a generic library has the most complete implementation of his ideas, away from project-specific contexts and constraints. Arjuna encapsulates Selenium completely and has its own DSL. It similarly encapsulates pytest and many of its plugins along with file readers, XML/JSON parsers, and so on. It uses Python’s advanced coding constructs to provide a very flexible and intuitive Tester Programming Interface (TPI).
