Getting NullPointerException while accessing the SuperClass method call using powermock
While running the below mentioned testclass getting NullPointerException error at above mentioned line in switch(super.getType())
public class CommandParamInput extends AbstractCommandParam {
public CommandParamInput(
final ParameterFeedType commandParameterSourceToSet,
final Object definedValueToSet) {
this.commandParameterSource = commandParameterSourceToSet;
this.definedValue = definedValueToSet;
}
public void evaluateValue(final FDPRequest fdpRequest)
throws EvaluationFailedException {
switch (super.getType()) {
case ARRAY:
evaluateComplexValue(fdpRequest);
break;
}
}
}
