All Implemented Interfaces:

Constraint

public class MethodBasedConstraint
extends AbstractConstraint

Defines a constraint for combinatorial testing as a collection of parameters names and a function which can check whether any given value assignment for those parameters is valid or not according to some logic defined by the function.

Constructor Detail

MethodBasedConstraint

public MethodBasedConstraint(String name,
                             List<String> parameterNames,
                             ConstraintFunction constraintFunction)

Creates a constraint using MethodBasedConstraint(String, List, ConstraintFunction, ConstraintStatus) with ConstraintStatus.UNKNOWN

Parameters:

name - name to improve readability without further semantics

parameterNames - the names of all involved parameters. Must not be, or contain null, or be empty

constraintFunction - the function by which the values for the parameters are constrained. Must not be null

MethodBasedConstraint

public MethodBasedConstraint(String name,
                             List<String> parameterNames,
                             ConstraintFunction constraintFunction,
                             ConstraintStatus constraintStatus)

Creates a new constraint. It is most efficient if only the parameters really involved and not additional ones are given.

Parameters:

name - a name to improve readability without further semantics

parameterNames - the names of all involved parameters. Must not be, or contain null, or be empty

constraintFunction - the function by which the values for the parameters are constrained. Must not be null

constraintStatus - status is either Unknown or Correct which is related to conflict detection

Method Detail

checkIfValid

public boolean checkIfValid(Combination combination)

Description copied from interface: Constraint

Checks whether the given combination is valid or not.

Parameters:

combination - combination to be checked.

Returns:

true iff the combination is valid.

getConverterFactory

public ConstraintConverterFactory getConverterFactory()

Returns:

ConstraintConverterFactory that can be used to convert this constraint.

getConstraintFunction

public ConstraintFunction getConstraintFunction()
