Multiple condition coverage (MCC) is also called condition combination coverage. For each decision all the combinations of conditions should be evaluated.
Multiple condition coverage (MCC) example
| if(a>10 && b>20)

Test Requirements MCC
There are two conditions. So, total test requirement will be 22=4 test requirements.
| Test Requirements | Condition C1 | Condition C2 |
| 1 | T | T |
| 2 | T | F |
| 3 | F | T |
| 4 | F | F |
| TR | a | b | Condition | Test Case # |
| 1 | 20 T | 30 T | a>10, b>20 | 1 |
| 2 | 20 T | 10 F | a>10, b>20 | 2 |
| 3 | 5 F | 30 T | a>10, b>20 | 3 |
| 4 | 5 F | 10 F | a>10, b>20 | 4 |
| Test Case # | Values input Pattern(a,b) |
| 1 | 20,30 |
| 2 | 20,10 |
| 3 | 5,30 |
| 4 | 5,10 |
Test Requirements MCC for three conditions
There are two conditions. So, total test requirement will be 23=8 test requirements.
| if(a>10 && b>20 OR c<30)
{ |
Test Requirements:
Total test requirement are 23=8
