decision-table-test-design

Overview

Per ISTQB CTFL Syllabus v4.0.1 §4.2.3, "decision tables are used for testing the implementation of requirements that specify how different combinations of conditions result in different outcomes" and are "an effective way of recording complex logic, such as business rules." This skill walks that derivation end to end: spec in, human-readable manual test cases out (step/expected tables, not code).

All syllabus claims below come from that v4.0.1 PDF (2024-09-15 revision); later references cite it as §4.2.3 without repeating the URL. One worked example (a shipping-fee rule) is carried through every step.
