The Condition Coverage Metric is like Decision Coverage, except that the decisions are split into elementary subexpressions (or conditions) that are connected by AND or OR operators. The coverage of a program is the number of executed statement blocks and conditions divided by the total number of them. Here each condition counts twice, which may result in a large number of possible outcomes in a complex decision.
This metric is also known as predicate coverage.
Note that 100% condition coverage does not guarantee full decision coverage. See Modified Condition/Decision Coverage (MC/DC) for a metric that overcomes this limitation.
