Destructive Testing
Destructive testing intentionally pushes a system beyond its normal operating limits to identify failure points and evaluate robustness.
“A test type that subjects a component or system to malicious inputs, abnormal conditions, or security exploits to induce persistent anomalous behavior.”

View the complete ISTQB GlossaryWhat is Destructive Testing?
The objective is to determine how a system behaves under extreme or abnormal conditions and whether failures occur safely and predictably.
Extreme conditions: Systems are stressed beyond expected usage.
Failure analysis: Observes how and when components fail.
Reliability improvement: Results help strengthen system robustness.
Real World Example
A regulated product team is preparing a release where Destructive testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Destructive 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 Destructive testing and similar ideas.
The page becomes useful in practice because Destructive testing is connected to a specific testing decision, not memorized as a detached definition.
