Test Basis

A Test Basis is the source of information used to define and design test cases. It is the foundation for all testing activities and ensures that tests are aligned with the software's specified requirements and expected behavior.

Example: For a new e-commerce website, the Test Basis for the shopping cart functionality would include the business requirements document, which states that users must be able to add, update, and remove items, as well as a user interface (UI) design mock-up that specifies the layout and behavior of the cart page. These documents provide the essential information needed to create detailed test cases.
