The document outlines functional system testing techniques including test cases, test suites, functional analysis, equivalence partitioning, and boundary value analysis. It discusses the goal of testing being to uncover defects rather than track down bugs. Coverage and choosing representative test cases are important. Equivalence partitioning identifies valid and invalid input ranges, and boundary value analysis chooses boundary values and those just outside boundaries. Examples demonstrate applying these techniques to test a traffic violation system and country club admission system.

14. Example: Functional Analysis II Defect diagnosis: Actual results: Passed Failed Test results A message dialog stating that violation “243567” is not stored in TVRS Enter “243567” at “Violation ID” text field and press the “Search” button “ Lookup Violation” dialog is displayed Press the “Yes” button Confirmation dialog is displayed Press “Delete” button Expected result Action Related use cases: “Lookup Traffic Violation”, “Remove Traffic Violation” Pre-conditions: 1. TVRS initialized with test1.db database 2. Violation 243567 displayed in the “Lookup Violation” dialog Test case ID: 134543
15. Example: Functional Analysis III Verify effects of change Filled when the test case is executed How do we know that violation 243567 is stored in the system? Can a tester diagnose the cause of a defect? In addition, a query could be run on the Offenders database
