C857 - Software Quality Assurance – WGU questions & answers 20233 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 decedents Integration 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 Unit and Functional testing verification that the programmer implemented the design correctly System testing validation that the system does what the customer wants it to do System testing steps functional testing, performance testing, acceptance testing, installation testing
