What is the test basis?

The test basis refers to the body of knowledge that is utilized for test analysis and design. It encompasses all of the documentation, requirements, specifications, and other sources of information that inform the testing process. This foundational element is critical because it provides the necessary context and criteria against which the software will be tested. A well-defined test basis allows testers to create meaningful test cases that effectively evaluate whether the software meets its requirements and functions as intended.

It is important to understand that while other aspects of testing, such as the timing of when to start testing or how to derive expected results, are relevant to the testing process, they do not capture the essence of what the test basis is. Instead, the test basis primarily serves as the reference point for understanding what should be tested and why, facilitating a more structured and effective approach to software testing.
