Automation in Selenium: Page Object Model and Page Factory
Proper test automation is not always easy to achieve and requires almost as much design and thought as needed for the software itself. In the agile way of development, tests are an essential ingredient in ensuring the quality of software. However, unless these test codes are maintainable, they can prove to be more of a nuisance, especially when it comes to automated testing of modern web applications. This article is an easy introduction to Selenium features Page Object and Page Factory, how they can be used to model web applications, and how to write maintainable test code using them.
