📖 What is Debugging?

Debugging is the process of finding, analyzing, and removing the causes of failures in software. Unlike testing, which focuses on showing that failures exist, debugging is performed by developers to fix the underlying defects.

🥋 Sensei Says:

"Don't confuse testing with debugging! Testing finds the failure, debugging fixes the defect. This distinction is heavily tested."

Equivalence Partitioning vs Boundary Value Analysis: ISTQB

Equivalence Partitioning (EP) divides input data into groups that should be processed identically, reducing test cases by testing one representative value per group. Boundary Value Analysis (BVA) complements this by testing the edges of these partitions, where defects frequently occur, ensuring the system handles limits and transitions correctly.
