Lecture Software quality assurance - Chapter 7: Dynamic techniques

Learning objectives in chapter 7 "Dynamic techniques" includes: Explain the characteristics and differences between specification-based testing, structure-based testing and experience-based testing; compare the terms test condition, test case and test procedure; write test cases from given software models using techniques: equivalence partitioning, boundary value analysis, decision tables, state transition testing;. | 8 3 2015 1 Overview 2 Life cycle components 3 Infrastructure components 4 Management components 5 Standards and Organizing 6 Static tesing 7 Dynamic testing 8 Test management 9 Tools Learning objectives Explain the characteristics and differences between specification-based testing structure-based testing and experience-based testing Compare the terms test condition test case and test procedure Write test cases from given software models using techniques equivalence partitioning boundary value analysis decision tables state transition testing Write test cases from given control flows using techniques statement coverage decision coverage Slide 2 References Dorothy Grahamet Erik van Veenendaal Isabel Evans Rex Black.
