Test Pyramid
The test pyramid is a model that recommends having many fast, low-level automated tests and fewer slower, high-level tests.
“A graphical model representing the relationship of the amount of testing per level, with more at the bottom than at the top.”

It helps teams build efficient and maintainable automated test suites by balancing different test levels appropriately.
Layered testing: More unit tests than UI tests.
Efficiency: Fast tests provide quick feedback.
Cost optimization: Lower-level tests are cheaper to maintain.
Visual Example
Real World Example
A regulated product team is preparing a release where Test pyramid appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Test pyramid 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 pyramid and similar ideas.
The page becomes useful in practice because Test pyramid is connected to a specific testing decision, not memorized as a detached definition.
