TCS Automation Test Engineer Interview Questions, Process, and Tips

Q1. Explain Object-Oriented Programming (OOP) concepts with examples.
Ans. 
OOP is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
• OOP focuses on creating objects that interact with each other to solve a problem.

• Encapsulation: Objects can hide their internal state and require interaction through defined interfaces. Example: Class Car with private variables like speed and methods like accelerate.

• Inheritance:...read more

Q4. How do you handle test data privacy and security in your automation tests?
Ans. 
Test data privacy and security is ensured by using anonymized data, encryption, access controls, and secure storage.
• Anonymize sensitive data by replacing real values with fake ones

• Encrypt test data during transmission and storage

• Implement access controls to restrict who can view or modify test data

• Store test data securely using encryption and regular backups

Q5. What are test hooks, and how do they impact automation test execution?
Ans. 
Test hooks are methods or functions that allow testers to access internal code for testing purposes.
• Test hooks are used to inject test code into the application being tested.

• They can be used to monitor and manipulate the behavior of the application during testing.

• Test hooks can be implemented using tools like Selenium or TestNG.

• They impact automation test execution by providing access to internal components for testing

Q6. What is Behavior-Driven Development (BDD), and how does it relate to automation testing?
Ans. 
BDD is a software development approach that encourages collaboration between developers, QA, and non-technical stakeholders to define and test system behavior.
• BDD focuses on defining the behavior of a system through examples in plain text

• It uses a common language (like Gherkin syntax) to describe features and scenarios

• Automation testing in BDD involves writing automated tests that validate the behavior described in the...read more
