The document discusses the page object pattern in Selenium-based web test automation, emphasizing the need for clear separation between page code and test code to enhance maintainability and scalability. It outlines both the preferences and challenges encountered when automating web application tests, particularly within agile environments. A new generational approach to creating page objects and tests is proposed to better handle business workflows and improve codebase accessibility.
![Selenium-Based Test Automation
• Overview
• Page Objects
• Some ‘prefer’ items
• Some Challenges
• A new way

![Overview
• We need to assertively test web applications
• Web applications involve significant business workflows
• Web applications involve more rather than less pages
• Test automation is a project concern

![Page Objects
• Page Objects are a pattern for Page classes
• See: https://www.martinfowler.com/bliki/PageObject.html
• Each page in a targetWeb application requires a Page Object class
• Provide a clear separation of «page code» from «test code»

![Prefer Items
• When automatingWebApplication tests, we would prefer to:
• Maximise separation of «page code» from «test code»
• Maximise maintainability and scalability of test collections
• Attack challenging business workflow
• Do more rather than less testing
• Participate in Continuous Integration
• Participate in Agile projects (Stories,Tasks, Stand-Ups, Demo’s)

![Challenges
• When automatingWebApplication tests, the challenges are:
• Achieving, routinely, a strong separation of «page code» from «test code»
• Being able to routinely deal challenging business workflow
• Developing tests as well as Page Objects, with confidence
• Going for the «more rather than less» proposition
• Participate in Agile projects given the test dev. time/effort involved

![The New Way
Generation of Page Objects
• Pages
• Page ‘content’
Step 1
Definition
• Read Definition
• Write PO
Classes
Step 2
Generate • Write tests
• Use PO classes
Step 3Test

![Outcome
• With the new generational approach:
• Achieved -> a strong separation of «page code» from «test code»
• Achieved -> being able to routinely deal with challenging business workflow
• Achieved -> developing tests as well as Page Objects, with confidence
• Achieved -> going for the «more rather than less» proposition
• Achieved -> Able to participate fully inAgile projects
• Achieved -> maintainable, scalable and accessible test automation codebase

![Generation
This shows the generation of the
Page Object classes. Some page
definitions are “empty” so don’t
have output. For real tests there
would be many more Pages.

![Write Tests
This shows the a fragment of a test
which uses the generated Page
Objects.This test asserts the
existence and associated content of
the Main Page footer items.
