Inheritance is a mechanism in object-oriented programming where a class acquires the properties of another class.

• Inheritance allows for code reusability and promotes a hierarchical organization of code.

• The class that is being inherited from is called the superclass or parent class, while the class that inherits is called the subclass or child class.

• The subclass can access all the public and protected methods and variab...read more

Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not.

• Testing is done to identify defects or errors in software

• It involves executing a system or application with the intent of finding bugs

• Testing can be done manually or through automated tools

• Types of testing include functional, performance, security, and usability testing

Testing Life Cycle includes planning, designing, executing and reporting. Bug Life Cycle includes reporting, assigning, fixing and verifying.

• Testing Life Cycle involves planning, designing, executing and reporting of tests.

• Bug Life Cycle involves reporting, assigning, fixing and verifying bugs.

• Testing Life Cycle starts with requirement analysis and ends with test closure.

• Severity is the measure of how much a bug affects the system's functionality or performance.

• Priority is the measure of how urgently a bug needs to be fixed.

• A high severity bug may not have a high priority if it does not affect critical functionality.

• A low severity bug may have a high priority if it affects critical functionality.

• If n is not divisible by any number, it is prime

I suggest using a hybrid automation framework for testing Amazon application.

• Use Selenium WebDriver for web automation

• Use Appium for mobile automation

• Use TestNG for test management and reporting

• Use Page Object Model for better code maintenance

• Use data-driven approach for test data management

• Use Jenkins for continuous integration and deployment
