  3. Course Description • Software Testing and Verification is a survey course on concepts, principles, and techniques related to software testing and formal program verification. • It focuses primarily on issues relevant to software engineers (as opposed to system-level testers, QA personnel, etc.).

  4. Course Description (cont’d) • You will: • Learn to apply various black-box and white-box testing methods, • Become acquainted with various integration testing strategies, and • Become acquainted with techniques for proving the functional correctness of sequential programs.

  5. Course Description (cont’d) • Topics include: black-box and white-box test case design strategies, incremental integration testing techniques, inspections and reviews, axiomatic verification techniques, predicate transforms, and function theoretic-based verification. • You will have the opportunity to practice the techniques presented in class via individual and/or group exercises.

  6. Prerequisites • Successful completion of an upper division (undergraduate) or graduate-level software engineering survey course, or equivalent professional experience • Familiarity with programming using a high-level language (C, C++, Java, etc.) • Basic knowledge of algorithms, data structures, object-oriented programming principles, and discrete math

  7. Prerequisites (cont’d) • A self-assessment “pre-test” will assist students in determining their preparedness for the course vis-à-vis coverage of a small subset of prerequisite knowledge.

  8. Class Meeting Times and Location (On-Campus Students) • Tuesday: 5th and 6th (11:45-1:30) • Thursday: 6th (12:50-1:40) • Room: CSE 122

  18. Optional Reference Text • An optional textbook, Pezze and Young's Software Testing and Analysis, Wiley, 2008, is recommended for students who wish to have additional software testing and analysis reference material at their disposal.

  19. Outline of Topics • Introduction to V&V Techniques and Principles • Requirements and Specifications • Black-Box Test Case Design Strategies • Partition testing • Combinatorial approaches • Other strategies

  20. Outline of Topics (cont’d) • White-Box Test Case Design Strategies • Logic coverage • Dataflow coverage • Path conditions & symbolic evaluation • Other strategies • Integration and Higher Level Testing • Testing Object-Oriented Software

  21. Outline of Topics (cont’d) • Reviews and Inspections • Testing Tools ----------------------------------------- • Formal Program Specification • Axiomatic Verification • Weak correctness • Rules of inference: sequencing, selection statements, iteration • Strong correctness Exam 1

  22. Outline of Topics (cont’d) • Predicate Transforms • Proving strong correctness • Rules for assignment statements, sequencing, selection statements, iteration • Functional Verification • Complete and sufficient correctness • Compound programs and the Axiom of Replacement

  24. Examinations and Grades • Course grades are based solely on two equally weighted 90-minute exams. • Histograms of numeric scores will be provided with solution notes. • Course letter grades will be determined at the end of the semester based on separate “curves” for CEN 4072 and CEN 6070 students.

  25. On-Campus Exam Schedule • Exam 1: (topics through “Testing Tools” + associated readings) – October 23 (tentative) • Exam 2: (remaining topics + associated readings) – December 4 Note: there is no (comprehensive) “final exam” for this course.

  26. Exam Procedures for EDGE Students • Proctors will be instructed to schedule a single exam time during normal working hours for all students at each site. If this is not possible, exams may be scheduled outside normal working hours (e.g., in the evening). • Exams are made available to proctors the same day they are administered to on-campus students. • Proctors should return ORIGINAL, completed exams directly to the instructor, preferably via overnight delivery.

  27. Make-Up Exam Policy • Students are expected to make every effort to be available at scheduled exam times. • If missing an exam is unavoidable, please contact the instructor as far in advance as possible. • An oral make-up exam may be administered in cases of unavoidable absence.

  28. Problem Sets • There will be 7 optional, non-graded problem sets. • Some problems will require the creativeapplication of techniques presented in class. • You may work on the problems alone or in groups. • To receive feedback on your work, solutions must be submitted by the due date. • Exams assume a thorough understanding of the problems and their solutions.

  29. Class Attendance (On-Campus Students) • On-campus students are strongly encouraged – but not required – to attend all lectures. • You will, however, be responsible for all announcements and course materials discussed in class regardless of whether or not you attend.

  30. Academic Integrity • You will be asked to sign the following state-ment on all exams in this course: On my honor, I have neither given nor received unauthorized aid on this examination.

  31. Other Info For info regarding: • Accommodation for Students with Disabilities, • UF Counseling Services, • UF Software Use Policies, and • Instructor background, please see the course syllabus.
