Development of Test Cases
Complete testing is impossible
⇓ Testing cannot guarantee the absence of faults
⇓ How to select subset of test cases from all possible test cases with a high chance of detecting most faults ?
⇓ Test Case Design Strategies
CISS
Sources for test case design • The requirements to the program (its specification) • An informal description • A set of scenarios (use cases) • A set of sequence diagrams • A state machine • The program itself • A set of selection criteria • Heuristics • Experience
CISS
Test case execution • Single stepping via a debugger • Very clumsy for large programs • Hard to rerun • Manual via a set of function calls • Hard to check when the number of test cases grows • Fully automatic without programmers assistance • Not possible so far • Offline/online • Fully automatic with programmers assistance • Started with Junit • State of the art • Growing interest
CISS
White-Box Testing • Testing based on program code • Extent to which (source) code is executed, i.e. Covered • Different kinds of coverage : • statement coverage • path coverage • (multiple-) condition coverage • decision / branch coverage • loop coverage • definition-use coverage • …..
CISS
White box testing: flow graphs • Syntactic abstraction of source code • Ressembles classical flow charts • Forms the basis for white box test case generation principles • Purpose of white box test case generation: Coverage of the flow graph in accordance with one or more test criteria

White-Box : Statement Testing • Execute every statement of a program • Relatively weak criterion • Weakest white-box criterion
