Smoke Test
A smoke test is a preliminary set of tests that verifies whether the most important functions of a build work well enough for further testing to continue.
“A test suite that covers the main functionality of a component or system to determine whether it works properly before planned testing begins.”

Smoke testing quickly identifies critical failures that would prevent more detailed testing from being worthwhile.
Build verification: Confirms the build is stable enough for testing.
Fast execution: Covers only essential functionality.
Early feedback: Detects major failures immediately.
Real World Example
A regulated product team is preparing a release where Smoke test appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Smoke test 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 Smoke test and similar ideas.
The page becomes useful in practice because Smoke test is connected to a specific testing decision, not memorized as a detached definition.
