Class TestModel

java.lang.Object

de.rwth.swc.coffee4j.engine.TestModel

public class TestModel
extends java.lang.Object

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

TestModel

public TestModel(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()

Returns:

the testing strength

getParameterSizes

public int[] getParameterSizes()

Returns:

the number of values for each parameter

getForbiddenTupleLists

public java.util.List<TupleList> getForbiddenTupleLists()

Returns:

all forbidden combinations. Tests containing these combinations cannot be executed

getErrorTupleLists

public java.util.List<TupleList> getErrorTupleLists()

Returns:

all error combinations. Tests containing these combinations can be executed but should cause an error

getExclusionConstraints

public java.util.List<Constraint> getExclusionConstraints()

getErrorConstraints

public java.util.List<Constraint> getErrorConstraints()

getNumberOfParameters

public int getNumberOfParameters()

Returns:

the number of parameters

getSizeOfParameter

public int getSizeOfParameter(int parameterId)

Parameters:

parameterId - the id of a parameter in the model

Returns:

the number of values this parameter has

equals

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
