Päättelytestauksella

Päättelytestauksella refers to deductive testing, a software testing method that uses logical reasoning and deduction to create test cases. It is a black-box testing technique, meaning the internal structure or code of the software is not known to the tester. The focus is on understanding the requirements and specifications of the software to derive test scenarios.

This approach involves analyzing the problem domain, identifying potential inputs and their expected outputs, and then devising tests that verify the software's behavior against these expectations. Päättelytestauksella relies on the tester's ability to think critically and anticipate how the software should function under various conditions, including both valid and invalid inputs. It is often used in conjunction with other testing techniques to ensure comprehensive coverage.

The process typically begins with a thorough review of documentation, such as user stories, functional specifications, and design documents. From this, testers identify key functionalities and business rules. They then apply logical deduction to infer possible scenarios and edge cases that might not be explicitly stated but are implied by the requirements. This can involve techniques like equivalence partitioning and boundary value analysis, where testers deduce classes of input data that should behave similarly and test the boundaries of these classes. The ultimate goal is to uncover defects by systematically exploring the logical consequences of the software's intended behavior.
