In software testing, the modified condition/decision coverage (MC/DC) is a code coverage criterion that requires all of the below during testing: 1. * Each entry and exit point is invoked 2. * Each decision takes every possible outcome 3. * Each condition in a decision takes every possible outcome 4. * Each condition in a decision is shown to independently affect the outcome of the decision. Independence of a condition is shown by proving that only one condition changes at a time.
