Desired capabilities are a set of properties or attributes that define the behavior of a browser or mobile device in Selenium automation testing.

• Desired capabilities are key-value pairs that are used to configure the WebDriver instances in Selenium.

• They can be used to set properties like browser name, version, platform, and other settings.

• For example, setting 'browserName' to 'chrome' will launch the Chrome browser dur

To run tests on iOS or Android devices using Appium, specify the platformName capability in desired capabilities.

• Specify platformName capability as 'iOS' for iOS devices and 'Android' for Android devices

• Include other necessary desired capabilities like deviceName, platformVersion, appPackage, appActivity, etc.

• Example: capabilities.setCapability('platformName', 'iOS');

Setting up automation for iOS devices involves using tools like Appium and Xcode for testing mobile applications.

OOPs concepts used in the framework include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance is used to create a parent-child relationship between classes. For example, a base class 'Page' can be inherited by 'HomePage' and 'LoginPage' classes.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass. For instance, a 'click' method can be implemented different...read more

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.
