BCS Software Engineering Principles 2

Question 1

What is the purpose of unit testing?

Accepted Answer

Testing individual components or functions in isolation to verify they work correctly

Answer

Unit testing verifies that individual functions, methods, or components work correctly in isolation, catching bugs early in the development process.

Question 2

Which design pattern separates object construction from representation, allowing the same construction process to create different representations?

Accepted Answer

Builder pattern

Answer

The Builder pattern separates the construction of a complex object from its representation, allowing different representations to be created through the same process.

Question 3

In object-oriented programming, what is encapsulation?

Accepted Answer

Bundling data and methods that operate on that data within a class, restricting direct access from outside

Answer

Encapsulation bundles data (attributes) and methods together in a class and restricts external access using access modifiers (private, protected, public).

Question 4

What is refactoring in software development?

Accepted Answer

Restructuring existing code without changing its external behavior to improve readability or reduce complexity

Answer

Refactoring improves code structure, readability, and maintainability without altering its observable behavior, reducing technical debt over time.

Question 5

What does CI/CD stand for in modern software development?

Accepted Answer

Continuous Integration / Continuous Delivery (or Deployment)

Answer

CI/CD stands for Continuous Integration (frequently merging code and running automated tests) and Continuous Delivery/Deployment (automatically preparing or releasing builds).
