black-box testing
📗 CTFL
Official ISTQB Definition
Testing based on an analysis of the specification of the component or system.
3 Ways to Think About It
The Quick Take
Testing without looking at the code — just focusing on inputs and outputs.
Look Closer
Checking software from the outside, like a user would, without knowing how it works inside.
The Bottom Line
Treating the system as a 'black box' where you only see what goes in and what comes out.
