The Power of Polymorphism: Testing Android And iOS From A Single Test Suite - Craig Schwarzwald
The Power of Polymorphism: Testing Android And iOS From A Single Test Suite - Craig Schwarzwald – Senior Automation Engineer, Vanguard
Abstract
Maintaining end-to-end test suites is always a challenge. Mobile typically multiplies that challenge by forcing companies to maintain multiple suites across different mobile OSs. However, we can utilize Object-Oriented design patterns to enable polymorphism and allow us to run the same test cases on multiple different platforms. In this presentation, Craig Schwarzwald will show you how. The strategy is as follows:
Create interface classes for any/all Appium Page Objects (borrowing a Selenium term in our case representing each mobile screen)
Create common implementations of those interfaces for any/all locators that are the same between the different mobile platforms.
Create platform specific implementations of those interfaces for ONLY the locators that are different across platforms.
Create tests that reference the interfaces (not the implementations).
By following the above rules, we can generate a single test suite that can easily run all our tests across multiple different mobile OS platforms! Come prepared to view code examples of how we can put these Object-Oriented design patterns in place so you can go back to your organization armed with the specifics of how to implement these changes at your company.
