"Moving from manual testing to automation testing is like going from haystack to high-tech! It’s a whole new level of excitement and challenge. It’s like going from playing checkers to playing chess, where every move is strategic and futuristic. Embracing automation testing is like leveling up in the game of tech!" 😎🚀 #gamechanger #techsavvy #embracethechallenge"

Manual Testing to Automation Testing Experienced Mock Interview 🧪


  • Janani, with years of experience in independent testing and gaming, is seeking an automation testing career.

JVM and Main Method

  • The Java Virtual Machine (JVM) looks for the main method, which must have a public static void main(String[] args) signature.

Compilation and Interpretation

  • Compilation looks for syntax errors, while interpretation converts the Java file to a class file and then to a binary file using JVM, JRE, and JIT.

Conditional Statements and Comparison Operators

  • If-else and nested else-if are conditional statements, while comparison operators include less than, greater than, equal to, and more.

Method Overloading and Inheritance

  • Method overloading involves developing multiple methods with the same name but different parameters, while inheritance involves inheriting properties between classes.

Overriding and Super Calling Statement

  • Overriding involves developing a method with the same signature and different implementation, while the super keyword calls the parent class’ constructor.

Local and Global Variables, Final Variable, and ‘this’ Keyword

  • Local variables are declared inside a method, while global variables are declared outside of a method. ‘this’ is used when dealing with variables of the same name.

Scanner Class and Exception Handling

  • The Scanner class allows for input values, while exception handling is used to manage runtime errors using try, catch, throw, and throws.

Type Casting and Abstract Method

  • Type casting involves converting data types, and an abstract method has no implementation logic in the parent class.

Concrete Class and Interface

  • Concrete classes have both abstract and concrete methods, while interfaces only have abstract methods, achieving complete abstraction.

Abstraction, Encapsulation, and Polymorphism

  • Abstraction hides implementation logic and showcases functionality, encapsulation restricts direct access to variables, and polymorphism enables performing the same method in different life cycle stages.

Array and Collection

  • Arrays store homogeneous data types, and collections allow for dynamic size and heterogeneous data storage.

Exception Handling Practice

  • Practice programming with error handling using try and catch blocks for various scenarios.


  • Janani navigated the different aspects of manual testing, automation testing, and programming with ease and demonstrated a strong understanding of these topics.
