Black Box Testing, either functional or non-functional, is testing that has no reference to the internal structure of the component 🧩 or system.
Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal 📦 structures or workings.
This method of testing can be applied virtually to every level of software testing:
-unit,
-integration,
-system, and
-acceptance.
It is sometimes referred to as specification-based testing.
