Par Sheet Testing
PAR sheet testing is a test design technique that uses predefined parameter sheets or structured input combinations to systematically verify software behavior across multiple scenarios.
“A test type to determine that a game returns the correct mathematical results to the screen, to the players' accounts, and to the casino account.”

View the complete ISTQB GlossaryWhat is Par Sheet Testing?
Parameter sheets organize test data into reusable combinations, helping testers execute consistent and repeatable tests for configurable systems.
Structured input data: Parameters are documented before execution.
Reusable design: Parameter sheets simplify repeated testing.
Consistency: Standardized data improves test repeatability.
Real World Example
A regulated product team is preparing a release where Par sheet testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Par sheet 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 Par sheet testing and similar ideas.
The page becomes useful in practice because Par sheet testing is connected to a specific testing decision, not memorized as a detached definition.
