  2. Learning Objectives • Various test processes and continuous quality improvement • Types of errors and fault models • Methods of test generation from requirements • Behavior modeling using UML: Finite state machines (FSM) • Test generation from FSM models

  3. Learning Objectives (contd) • Input space modeling using combinatorial designs • Combinatorial test generation • Test adequacy assessment using: control flow, data flow, and program mutations • The use of various test tools • Application of software testing techniques in commercial environments

  4. Test processes and continuous quality improvement Test plan: Chapter 1.5 Test metrics: Chapter 1.6 Defect management: Chapter 1.9 Walkthroughs and inspection: Chapter 1.12 Test process models: Chapter 1.18.5

  5. Types of errors and fault models Chapter 1.1

  7. Behavior modeling using UML: Finite state machines (FSM) FSM basics: Chapter 3.2 Microsoft project AEC project: parsing

  8. Test generation from FSM models Spec Explorer W-method: Chapter 3.6 State, transition, and switch covers: Chapter 3.9

  9. Input space modeling using combinatorial designs Test configurations and modeling the input space: Chapter 4.1 Fault model: Chapter 4.3

  10. Combinatorial test generation MOLS: 4.8 Covering arrays: 4.9, 4.10, 4.11
