Selenide’s capabilities enable testers to execute these native events without delving into the intricacies of low-level code, enhancing the efficiency and readability of test scripts.

Combined Attribute:

Selenide introduces the CombinedBy class for defining custom attributes. Amuthan explained how this feature enables users to create custom attribute conditions tailored to different platforms.

By handling platform-specific logic internally, Selenide streamlines element selection and reduces the need for extensive platform-specific conditional code. This approach simplifies the process of selecting elements with specific attributes, promoting code simplicity and maintainability.

Dynamic Locators:

Dynamic locators, particularly when involving index-based selections, can pose challenges in Appium. Amuthan illustrated how Selenide simplifies dynamic locator handling by allowing users to define dynamic locators using a single CombinedBy instance.

This capability reduces the complexity of managing dynamic locators and minimizes the need for conditional code in test scripts. Developers can now create more robust and maintainable tests, even when dealing with dynamically changing elements.

Scroll/Swipe to Element:

Scrolling or swiping to locate elements in Appium can be intricate, often requiring multiple steps and error handling. Amuthan highlighted that Selenide-Appium offers built-in methods to simplify these interactions.

With Selenide-Appium, testers can efficiently scroll or swipe to elements, significantly enhancing the ease of locating and interacting with elements within the app. This capability enhances the overall robustness and readability of test scripts.

Triple Click — Custom Command:

Amuthan discussed the flexibility of Selenide-Appium in creating custom commands to address unique testing scenarios. He showcased how users can implement custom commands by extending Selenide’s functionality.
