Test Case
A test case is a set of preconditions, inputs, actions, expected results, and postconditions used to verify a specific test objective.
“A set of preconditions, inputs, actions (where applicable), expected results and postconditions, developed based on test conditions.”

Test cases provide repeatable instructions that help testers consistently validate software behavior and document testing results.
Detailed procedure: Specifies how to execute a test.
Expected results: Defines the correct outcome.
Repeatability: Different testers can execute the same test consistently.
Real World Example
A regulated product team is preparing a release where Test case appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Test case 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 Test case and similar ideas.
The page becomes useful in practice because Test case is connected to a specific testing decision, not memorized as a detached definition.
