21. At first glance .. Here’s a document: review this (or Inspect it)

22. Reviews: time and size determine rate Time Checking Rate Size 2 hrs? 100 pages? 50 pages per hour Checking Rate

23. Review “Thoroughness”? ordinary “review” - finds some faults, one major, fix them, consider the document now corrected and OK major minor minor

24. Inspection: time and rate determine size Time Checking Rate Size 2 hrs? Optimum: 1 page * per hour 2 pages (at optimum rate) Size * 1 page = 300 important words

30. Data flow analysis faults n := 0 read (x) n := 1 while x > y do begin read (y) write( n*y) x := x - n end Data flow anomaly: n is re-defined without being used Data flow fault: y is used before it has been defined (first time around the loop)

34. Which flow graph is most complex? 1 2 3 5 What is the cyclomatic complexity?

35. Example control flow graph Result = 0 Right = 0 DO WHILE more Questions IF Answer = Correct THEN Right = Right + 1 ENDIF END DO Result = (Right / Questions) IF Result > 60% THEN Print "pass" ELSE Print "fail” ENDIF do if r=r+1 end init if res pass fail end Pseudo-code:

38. Summary: Key Points Reviews help to find faults in development and test documentation, and should be applied early Types of review: informal, walkthrough, technical / peer review, Inspection Static analysis can find faults and give information about code without executing it Static testing 1 2 4 5 3 6
