condition determination testing: A white box test design technique in which test cases are independently affect a decision outcome that have been exercised by a test case suite.100 % condition determination coverage implies 100 % decision condition coverage condition determination coverage: The percentage of all single condition outcomes that independently affect a decision outcome that have been exercised by a test case suite. 100% condition determination coverage implies 100% decision condition coverage.

Rules!!
Condition determination testing - the possible combinations of true/false conditions that can affect decisions (branches) are identified.
100% multiple condition coverage implies 100% condition determination coverage modified condition decision coverage (MC/DC) = condition determination coverage
modified multiple condition coverage = condition determination coverage modified condition decision testing = condition determination testing modified multiple condition testing = condition determination testing
