Class ExperimentTest

java.lang.Object

jasima.core.util.ExperimentTest

public class ExperimentTest
extends Object

Utility class that can be used as a base class for JUnit tests which check for many results of an Experiment at once. Deriving a new test class from ExperimentTest and calling checkResults(Map, Map) many results of an experiment can be validated with a single method call.

Method Detail

checkKeySets

protected void checkKeySets(Map<String,Object> resActual,
                            Map<String,Object> resExpected)

Checks whether key sets of actual and expected results are the same.

Parameters:

resActual - The map of results actually obtained.

resExpected - The map of expected results.

checkResults

protected void checkResults(Map<String,Object> resActual,
                            Map<String,Object> resExpected)

Checks if all keys in resExpected are also present in resActual and have the same values. Additional keys in resActual as well as the key "runTime" are ignored.

Parameters:

resActual - The map of results actually obtained.

resExpected - The map of expected results.

checkFloat

protected void checkFloat(String name,
                          float act,
                          float exp)

checkDouble

protected void checkDouble(String name,
                           double act,
                           double exp)

checkValueStat

protected void checkValueStat(String name,
                              SummaryStat exp,
                              SummaryStat act)
