All Implemented Interfaces:

TestFitnessFactory<MethodTraceCoverageTestFitness>

public class MethodTraceCoverageFactory
extends AbstractFitnessFactory<MethodTraceCoverageTestFitness>

MethodTraceCoverageFactory class.

Measures coverage of methods by analysing execution traces, that is, the method can be covered by indirect calls, not necessarily be an statement in a test case.
