Java OOPs concepts are used in automation framework design for better code organization and reusability.

• Encapsulation: Used to hide the internal implementation details of classes and provide access through methods.

• Inheritance: Allows for code reuse by creating parent-child relationships between classes.

• Polymorphism: Enables methods to behave differently based on the object they are called on.

• Abstraction: Helps in defin...read more

OTP can be handled by generating, sending, and verifying it in automated tests.

Transform the input string by replacing spaces with hyphens and enclosing it in curly braces.

• Replace spaces with hyphens: 'My name is so and so' becomes 'My-name-is-so-and-so'.

• Implicit wait is set using driver.manage().timeouts().implicitlyWait() method

• Explicit wait is implemented using WebDriverWait class in Selenium

• Implicit wait is not recommended as it can slow down the test execution

• Explicit wait is more flexible and efficient as it waits for a specific condition to be met
