Test Adaptation Layer
A test adaptation layer is an abstraction layer within a test automation framework that isolates test scripts from the implementation details of the system under test.
“The layer in a test automation architecture which provides the necessary code to adapt test scripts on an abstract level to the various components, configuration or interfaces of the SUT.”

View the complete ISTQB GlossaryWhat is Test Adaptation Layer?
It translates generic test actions into application-specific interactions, improving maintainability and reducing the impact of application changes on automated tests.
Abstraction: Separates test logic from implementation details.
Maintainability: Application changes require fewer script modifications.
Framework support: Common in layered automation architectures.
Real World Example
A regulated product team is preparing a release where Test adaptation layer appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Test adaptation layer 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 adaptation layer and similar ideas.
The page becomes useful in practice because Test adaptation layer is connected to a specific testing decision, not memorized as a detached definition.
