Test Basis

What is Test Basis?

Test basis refers to all the documentation and information from which test cases and test conditions are derived.

Common Sources of Test Basis

• Business and functional requirements documents.
• Design and architecture specifications.
• Use cases and user stories.
• Risk analysis documents.
• Regulatory or industry standards.
• The source code itself (for structure-based testing).

Why Test Basis Matters

A clear, well-documented test basis ensures test cases are grounded in real requirements rather than assumptions, and provides traceability back to the origin of every test.
