CONDITIONAL COVERAGE

Conditional coverage also called as expression coverage, will reveals how the variables or sub-expressions in conditional statements are evaluated. Expressions with logical operators are only considered.. The downside is that the conditional coverage measure doesn't take into consideration how the Boolean value was gotten from the conditions. Conditional coverage is the ratio of no. of cases checked to the total no. of cases present. Suppose one expression having Boolean expression like AND or OR, so entries which is given to that expression to the total possibilities is called expression coverage.

Conditional coverage report of the previous example:
At LINE 13
Combinations of STATEMENT c = (b && a)
B = 0 and a = 0 is Covered
B = 0 and a = 1 is Covered
B = 1 and a = 0 is Not Covered
b = 1 and a = 1 is Not Covered

At LINE 14 combinations of STATEMENT if ((c && f))
C = 0 and f = 0 is Covered
C = 0 and f = 1 is Not Covered
C = 1 and f = 0 is Not Covered
C = 1 and f = 1 is Not Covered

Total possible combinations: 8
Total combinations executed: 3
