3 Types of Acceptance Tests - Benchmark, Pilot, Parallel (details below) Benchmark tests - tests ran by users using *predefined test cases* Pilot tests - tests ran by users under *normal or everyday situation* Beta testing - done at customer's site Alpha testing - done at developer's site Parallel test - New system operates in parallel with previous version to make transition easier for user LOC measurement of productivity - Error per line of code is better. LOC is not good for all programs because it is hard to measure. Some programs only use one line. Cyclomatic complexity - a measure of the complexity of a module's decision structure. Module Design Complexity - iv(G); is the cyclomatic number for the module Design Complexity - SO; sum of iv(G) for itself and all decedentsIntegration complexity - S1; SO - n + 1 Module Integration testing - evaluate just the module and its immediate children Design Integration testing - evaluate the entire graph White box testing - look into program graph at cyclomatic #, basis, IP, DU path coverage, and program slice Functional testing - do not look at program structure, only at the specifications or requirements Unit level testing - White box and functional testing of each module Integration testing - integrate modules, that have been tested at unit level
