org.evosuite.testsuite.TestSuiteFitnessFunction

org.evosuite.coverage.dataflow.DefUseCoverageSuiteFitness

All Implemented Interfaces:

Serializable

public class DefUseCoverageSuiteFitness
extends TestSuiteFitnessFunction

Evaluate fitness of a test suite with respect to all of its def-use pairs First simple and naive idea: Just take each DUGoal, calculate the minimal fitness over all results in the suite once a goal is covered don't check for it again in the end sum up all those fitness and that is s the resulting suite-fitness
