Class InputParameterModel

java.lang.Object

de.rwth.swc.coffee4j.model.InputParameterModel

public final class InputParameterModel
extends Object

An representation of a input parameter model for combinatorial testing. Consists of a testing strength, readable name for identification, parameter, and forbidden and error constraints. This model defines all important aspects of one combinatorial test.

Constructor Detail

InputParameterModel

public InputParameterModel(int strength,
                           String name,
                           List<Parameter> parameters)

Creates a new model with no constraints.

Parameters:

strength - the testing strength. Must be at least one and at most the number of parameters

name - the name of the model. Should be human readable. Must not be null

parameters - all parameters of the model. Must not be, nor contain null and must not be empty. Must not contain parameters with duplicate names

InputParameterModel

public InputParameterModel(int strength,
                           String name,
                           List<Parameter> parameters,
                           Collection<Constraint> forbiddenConstraints,
                           Collection<Constraint> errorConstraints)

Creates a new model with all given configuration arguments.

Parameters:

strength - the testing strength. Must be at least one and at most the number of parameters

name - the name of the model. Should be human readable. Must not be null

parameters - all parameters of the model. Must not be, nor contain null and must not be empty.

forbiddenConstraints - all constraints which may never be violated as test inputs won't work then May not be, nor contain null

errorConstraints - all constraints which may be violated but will cause the system to throw an exception. * All in all describes input which should not be allowed. May not be, nor contain null

Method Detail

getStrength

public int getStrength()

Returns:

the testing strength

getName

public String getName()

Returns:

the descriptive name of the model

getParameters

public List<Parameter> getParameters()

Returns:

a copy of the list of all parameters of this model

getForbiddenConstraints

public List<Constraint> getForbiddenConstraints()

Returns:

a copy of the list of all forbidden constraints. Test inputs may never violate those constraints as they define combinations which are not possible testable (like testing safari on windows is not possible)

getErrorConstraints

public List<Constraint> getErrorConstraints()

Returns:

a copy of the list of all error constraints. Test inputs may violate these constraints but they define inputs on which the system under test should react in a destructive way like raising exception (like trying to parse "asfd" as a number)

size

public int size()

Returns:

the number of parameters

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

inputParameterModel

public static InputParameterModel.Builder inputParameterModel(String name)
