DevOps is a set of practices, cultural philosophies, and tools that unites software development (Development) and IT operations (IT Operations) teams to deliver applications and services faster, more reliably, and with continuous feedback. It emphasizes automation, monitoring, and collaboration throughout the application lifecycle — from coding and building to testing, deployment, and maintenance.

Testing is the systematic process in information technology of evaluating software to ensure it behaves as expected, meets requirements, and is free of defects. Testing helps detect bugs, validate functionality, and improve reliability, performance, and security before deployment.

Technically, Testing involves:

noun — "the art of chasing invisible bugs until your code behaves… reluctantly."

Debugging is the process in information technology of identifying, analyzing, and resolving errors or exceptions in software. It ensures that programs execute correctly, efficiently, and reliably. Debugging is essential for maintaining code quality, improving performance, and preventing unexpected behavior in applications and systems.
