  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

  6. Methods of test generation from requirements Equivalence partitioning: Chapter 2.3 Boundary value analysis: Chapter 2.4

  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

  11. Test adequacy assessment using: control flow, data flow, and program mutations Basics: 6.1 Criteria based on control flow: 6.2 (excluded 6.2.7) Criteria based on data flow: 6.3, 6.4.1, 6.4.2, 6.4.3

  12. The use of various test tools Unit testing: Achoo,JUnit, Pex/Moles, PyUnit Concurrency: ConTest Test automation: TestComplete Load and performance testing: JMeter GUI testing: Abbot, Guitar Combinatorial testing: AETG, FireEye Model based testing testing: Spec Explorer Coverage analysis: Corbertura Defect management: Bugzilla

  14. What did we not cover [1]? Regression testing (Chapter 5) Mutation testing (for test adequacy and enhancement; Chapter 7) Test generation from statecharts Test generation from timed-automata for real-time systems Test generation from formal specification (e.g.; Z) Testing concurrent programs

  15. What did we not cover [2]? Test process Test automation Error types and classification method

  16. Final Examination Tuesday May 3. 8-10am. Smith 208 Part A: Multiple choice, comprehensive [Closed book/notes] Part B: Few questions (3 or 4) [Open book/notes] FSM-based test generation, Combinatorial designs, Test adequacy
