Function point factors* - Inputs, Outputs, User inquiries, Data files to be accessed, Interfaces to other applications *Function point* - used early in lifecycle at requirements analysis as a mechanism to estimate the project with the use of a historical baseline for comparison *System testing steps* - functional testing, performance testing, acceptance testing, installation testing 3 Types of Acceptance Tests - Benchmark, Pilot, Parallel (details below) Alpha testing - done at developer's site Benchmark tests - tests ran by users using *predefined test cases* Beta testing - done at customer's site Big Bang Flaws - Not good for large systems. Does not scale well. Difficult or impossible to isolate faults Big Bang Integration - Test each module and then all of it together. Modules will need either drivers, stubs (defined below), or both depending on what layer. 2 step approach.Bottom up flaws - Not appropriate functionally decomposed system because they usually start from the top. Discovering major faults can be delayed. Doesn't reveal timing errors. Not good when there is a lot of interactions between components. Bottom up Integration -Need drivers to test from bottom module and move up. Good for O/O system because you start with basic components. Breadth (CPG) - number of statements within a construct Complexity adjustment - reflects the complexity of the whole application
