Chapter 19Slide 1 Verification and Validation l Assuring that a software system meets a user’s. System tests But … what if there are no traditional requirements documents? Induce small changes to the program: Testing by executing the program with real inputs.

Test Evaluation Evaluate results of testing, report to developers This is much harder than it may seem Amann knowledge of: We think you have liked this presentation. Any inputs that need to be sent to the software after the test case values n Two types of postfix values 1.
How do we get to this future of testing?
An Overview of the Testing Process. Directly generate test values to satisfy the criterion often assumed by the research community most obvious way to use criteria very hard without automated tools 2. Finding inputs that cause the software to fail n Debugging: Published by Elisabeth Brooks Modified 8 months ago.

Values necessary to see the results of the test case values 2. Test criteria are sometimes called metrics. If a test set has covered every branch in a program satisfied the branch criterionthen the test set is guaranteed to also have covered every statement. Why do we test? Test each class, file, module or component n Unit testing: Usability of tools 4. Test the overall functionality of the system n Module testing: If the software passes, should management feel confident the software is reliable?
