1. Software Testing Techniques Presented By Dr. Shazzad Hosain

3. A good test has a high probability of finding an error A good test is not redundant A good test should be “best of breed” A good test should be neither too simple nor too complex

5. 5 + 5 2 + 5 3 + …. 5 19

12. Basis set

13. Flow Graph

14. R1R1 R2R2 R3R3 R4R4 Conditions are not compound

15. Compound Logic Flow Graph IF a OR b THEN procedure x ELSE procedure y END IF a x b xy a or b xy

16. Deriving Test Cases Step 2: Determine the Cyclomatic Complexity Step 1: Draw the flow graph 6 regions

17. Step 3: Determine Basis Set of Paths

18. Step 4: Prepare Test Cases that will Force Execution of each Path in the Basis
