Method Detail

getName

public String getName()

addPlugin

public DataSet addPlugin(String pluginID_p)

activate additional plugin

Parameters:

pluginID_p - plugin ID

Returns:

this dataset object

addField

public Field addField(String name_p,
                      String[] domainList_p)

adds a field.

Parameters:

name_p - field name

domainList_p - Array list of domain values to be tested

Returns:

Field object

addFieldVerify

public Field addFieldVerify(String name_p,
                            String expr_p)

adds a verify field - field of which the value is derived from other fields using the expression. For example F1 + F4, where F1 and F4 are the field names.

Parameters:

name_p - field name

expr_p - groovy expression

Returns:

Field object

addField

public Field addField(String name_p,
                      Field.DataType dataType_p,
                      String[] domainList_p,
                      String coupledField_p,
                      boolean derived_p)

adds a field to the dataset.

Parameters:

name_p - field name, preferably a legal java variable name

dataType_p - bool, text, intNum, floatNum

domainList_p - Array list of domain values to be tested

coupledField_p - name of the field to be coupled with

derived_p - if the field is derived, meaning its value is derived from an expression specified in domainList_p

Returns:

Field object

addRelation

public Relation addRelation(String name_p,
                            String[] fieldNameList_p,
                            DataSet.Strength strength_p)

adds a relation to the dataset. A Relation is used to test a set of fields with a specific interaction strength. Data set may have 0 or many relations.

Parameters:

name_p - relation name

fieldNameList_p - list of field names to create the relation

strength_p - interaction strength to test, pairWise, threeWise, fourWise, fiveWise, sixWise

Returns:

Relation object

addConstraint

                                String thenExpr_p)
                         throws Exception

adds a constraint to the dataset. Test cases failing any of the constraints will be removed. Use Constraints to filter out invalid/unwanted test cases. String literal must be enclosed with double quotes.

Parameters:

ifExpr_p - boolean expression, for example Age < 30 && Fulltime_Student && Smoking = "NO"

thenExpr_p - boolean expression, for example Credit = 50

Returns:

Rule object

Throws:

Exception - on any error

saveToFile

public void saveToFile(String filePath_p)
                throws Exception

Throws:

Exception

fromFile

public static DataSet fromFile(String filePath_p)
                        throws Exception

Throws:

Exception
