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

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
5	a=7, b=6, True	a=2, c=5, False	a=2, d=5, False	False
6	a=7, b=6, True	a=2, c=5, False	a=9, d=8, True	False
7	a=7, b=6, True	a=7, c=6, True	a=2, d=5, False	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
