Design Patterns
Page Object Model, Page Factory, Screenplay, driver factories, and data-driven test architecture
- 1
Page Object Model
Learn the Page Object Model (POM) design pattern for writing maintainable and scalable Selenium tests.
Selenium 3 & 4 Stable - 2
Page Factory
Use Page Factory pattern to initialize page elements with annotations for cleaner page objects.
Selenium 3 & 4 Stable - 3
Data-Driven Testing
Run the same test with different data sets using external files, databases, and parameterization.
Selenium 3 & 4 Stable - 4
Screenplay Pattern
A user-centred alternative to Page Objects built from Actors, Abilities, Tasks, Interactions and Questions. When it beats POM, when it does not, and a complete implementation in four languages.
Selenium 3 & 4 Stable - 5
Driver Factory and Thread Safety
Build a WebDriver factory that reads configuration, supports local, Grid and cloud targets, and hands each parallel test its own driver via ThreadLocal or fixtures without leaks.
