Also called condition combination coverage.
For each decision all the combinations of conditions should be evaluated.
MCC for 2 conditions:
Example code:
| if(a>10 && b>20)
{ |
Test Requirements:
Total test requirement are 22=4
| Test Requirements | Condition C1 | Condition C2 |
| 1 | T | T |
| 2 | T | F |
| 3 | F | T |
| 4 | F | F |
| Test Requirements | a | b | Test Case # |
| 1 | 20 T | 30 T | 1 |
| 2 | 20 T | 10 F | 2 |
| 3 | 5 F | 30 T | 3 |
| 4 | 5 F | 10 F | 4 |
| Test Case # | Values input Pattern(a,b) |
| 1 | 20,30 |
| 2 | 20,10 |
| 3 | 5,30 |
| 4 | 5,10 |
MCC for 3 conditions:
| if(a>10 && b>20 OR c<30)
{ |
Test Requirements:
Total test requirement are 23=8
