  • 4. 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.).
  • 5. 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 .
  • 6. 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 individually or in groups, via non-graded, optional problem sets .
  • 7. Prerequisites
    • Successful completion of an upper division (undergraduate) or graduate-level software engineering survey course, or comparable professional experience (Off-campus EDGE students currently employed as software professionals automatically meet this requirement.) †
    • Familiarity with programming using a high-level language (C, C++, Java, etc.)
    • † If you do not meet this prerequisite, please plan to enroll in CEN 3031/
    • 5035 in AY10-11 and then register for CEN 4072/6070 in Spring11.
  • 8. Prerequisites (cont’d)
    • Basic knowledge of algorithms , data structures , object-oriented programming principles , and discrete math
    • --------------------------------
    • 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.
  • 9. Prerequisites (cont’d)
    • Students who have already taken CEN 4072 may NOT take CEN 6070 for credit…

    • If missing an exam is unavoidable (e.g., due to sickness, accident, or other reasons beyond your control), contact the instructor as far in advance as possible .
    (cont’d)
  • 30. Make-Up Exam Policy (cont’d)
    • Make-up exams, when possible, may be administered orally .
