Unit testing focuses on verifying the smallest testable parts of an application—individual functions or methods—in isolation from the rest of the system.

Question 4

What does the term 'technical debt' refer to in software development?

Accepted Answer

The accumulated cost of shortcuts and poor design decisions made to deliver faster

Answer

Technical debt represents the future rework required because quick or suboptimal solutions were chosen over better approaches during development.

Question 5
