Risk-based Testing
Risk-based testing is a testing approach in which testing activities are prioritized according to the identified risks associated with the product or project.
“A test approach in which the management, selection, prioritization, and use of test activities and resources are based on corresponding risk types and risk levels.”

Higher-risk areas receive greater testing effort, helping teams optimize limited resources while reducing the likelihood of critical failures.
Risk prioritization: Testing focuses on the most important risks first.
Efficient resource use: Testing effort matches business risk.
Decision driven: Risk assessments guide test planning and execution.
Real World Example
A regulated product team is preparing a release where Risk-based testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Risk-based testing as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Risk-based testing and similar ideas.
The page becomes useful in practice because Risk-based testing is connected to a specific testing decision, not memorized as a detached definition.
