What are the conditions in software testing?
Conditions are atomic conditions in expressions.
What are Decisions in software testing?
Decisions are the controls that can control the program flow after evaluating the full expression.
Multiple condition coverage in Software Testing
1 2 3 4 5 6 7 8 9 10 11 | If(a > b && a >c && a >d ) { } else { } |
Test Requirements
| Test Case ID | a > b | a >c | a >d | Output |
| Condition 1 | Condition 2 | Condition 3 | ||
| 1 | False | False | False | False |
| 2 | False | False | True | False |
| 3 | False | True | False | False |
| 4 | False | True | True | False |
| 5 | True | False | False | False |
| 6 | True | False | True | False |
| 7 | True | True | False | False |
| 8 | True | True | True | True |
Test cases
| Test Case ID | a > b | a >c | a >d | Output |
| Condition | Condition | Condition | ||
| 1 | a=2, b=5, False | a=2, c=5, False | a=2, d=5, False | False |
| 2 | a=2, b=5, False | a=2, c=5, False | a=9, d=8, True | False |
| 3 | a=2, b=5, False | a=7, c=6, True | a=2, d=5, False | False |
| 4 | a=2, b=5, False | a=7, c=6, True | a=9, d=8, True | False |

| 8 | a=7, b=6, True | a=7, c=6, True | a=9, d=8, True | True |
How many test cases required for Multiple condition coverage (MCC)
Total number of test cases = 2C
Explanation of formula:
Condition 1: a > b
Condition 2: a>c
Condition 3: a>d
23=8
Total test cases required = 8
