📖 What is Quality Control (QC)?

A reactive process consisting of activities to evaluate a work product to determine if it meets quality requirements. Testing is a major part of Quality Control.

🥋 Sensei Says:

"Unlike QA, QC focuses on the *product*. When you are executing tests to find bugs, you are performing QC, not QA."

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.
