Class CombinatorialTestModel

java.lang.Object

de.rwth.swc.coffee4j.engine.CombinatorialTestModel

All Implemented Interfaces:

InputParameterModel

public final class CombinatorialTestModel
extends java.lang.Object
implements InputParameterModel

A class containing all important information needed for one combinatorial test. This includes the desired testing strength, the parameters and forbidden/error constraints. Forbidden constraints should never appear in any test input as they just cannot be executed, while error constraints should lead to validation or other kinds of errors in an application and should therefore be tested

Constructor Detail

CombinatorialTestModel

public CombinatorialTestModel(int strength,
                              int[] parameterSizes)

Defines a new model without any constraints.

Parameters:

strength - the desired testing strength. Must be equal to or greater than one and at most the number of parameters

parameterSizes - the sizes of all parameters. [2, 3, 5] means the first parameter has 2 values, the second one 3 and the last one 5. All parameters need to have at least two values. Must not be null

CombinatorialTestModel

public CombinatorialTestModel(int strength,
                              int[] parameterSizes,
                              java.util.Collection<TupleList> forbiddenTupleLists)

Defines a new model with just forbidden constraints but no error constraints.

Parameters:

strength - the desired testing strength. Must be equal to or greater than one and at most the number of parameters

parameterSizes - the sizes of all parameters. [2, 3, 5] means the first parameter has 2 values, the second one 3 and the last one 5. All parameters need to have at least two values. Must not be null

forbiddenTupleLists - all forbidden combinations. Must not be null. The sizes of the corresponding parameters must be respected

CombinatorialTestModel

public CombinatorialTestModel(int strength,
                              int[] parameterSizes,
                              java.util.Collection<TupleList> forbiddenTupleLists,
                              java.util.Collection<TupleList> errorTupleLists)

Parameters:

strength - the desired testing strength. Must be equal to or greater than one and at most the number of parameters

parameterSizes - the sizes of all parameters. [2, 3, 5] means the first parameter has 2 values, the second one 3 and the last one 5. All parameters need to have at least two values. Must not be null

forbiddenTupleLists - all forbidden combinations. Must not be null. The sizes of the corresponding parameters must be respected. Must not contain duplicate ids

errorTupleLists - all error combinations. Must not be null. The sizes of the corresponding parameters must be respected. Must not contain duplicate ids or ids contained in the forbiddenTupleLists

Method Detail

getStrength

public int getStrength()

Specified by:

getStrength in interface InputParameterModel

Returns:

the testing strength

getParameterSizes

public int[] getParameterSizes()

Specified by:

getParameterSizes in interface InputParameterModel

Returns:

the number of values for each parameter
