Official ISTQB Definition
Activities focused on evaluating whether a product or component meets its quality requirements.
In simple words
QC = product focus — ‘does this actual build meet our quality bar?’. Testing is a QC activity.
Exam tip
Testing is a subset of QC, not QA. Don’t use the terms interchangeably on the exam.
