Apex - Test Batch class Execute method not covered code coverage - testing

Question

Batch apex class not covering execute method
Batch Apex Class : Trying to cover execute method but not covered in image above.
This batch class is on aggregate result. Please suggest me how to cover this batch class
It is working on search result of order if the status is based on filter then in execute method it will aggregate the value of fulfilment id of all orders related to it. based on their order status it executes.
global class UpdateOrderIntegrationStatus_Batch implements
Database.Batchable<AggregateResult>, Database.Stateful{
String status_filter = 'Waiting On Prior Order';
String query = 'select count(Id) cnt, Fulfillment__c from Apttus_Config2__Order__c'
+' where Fulfillment__c <> null and Order_Integration_Status__c = \''+status_filter + '\''
+' group by Fulfillment__c '
+' limit 50000';
public UpdateOrderIntegrationStatus_Batch(){}
public UpdateOrderIntegrationStatus_Batch(string q){
query = q;
}
global Iterable<AggregateResult> start(Database.BatchableContext BC){
//system.debug('>>>> query : ' + query)
return new AggregateResultIterable(query);
}
global void execute(Database.BatchableContext BC, List<sobject> results){
set<Id> fufillmentIds = new set<Id>();
for(Sobject sObj:results){
AggregateResult ar = (AggregateResult)sObj;
fufillmentIds.add((Id) ar.get('Fulfillment__c'));
}
List<Contract> fulfillments = [select id,(select Id, Order_Integration_Status__c from Orders__r order by Name asc) from Contract where id IN:fufillmentIds];
List<Apttus_Config2__Order__c> orderToUpdate = new List<Apttus_Config2__Order__c>();
String priorOrderIntegrationStatus = '';
for(Contract fulfillmentObj: fulfillments){
priorOrderIntegrationStatus = '';
for(Apttus_Config2__Order__c order: fulfillmentObj.Orders__r){
if(order.Order_Integration_Status__c == 'Processed'){
priorOrderIntegrationStatus = order.Order_Integration_Status__c;
}
else if(order.Order_Integration_Status__c == 'Error'){
break;
}
else if(order.Order_Integration_Status__c == status_filter && priorOrderIntegrationStatus == 'Processed' ){
order.Order_Integration_Status__c = 'Ready';
orderToUpdate.add(order);
priorOrderIntegrationStatus = order.Order_Integration_Status__c;
break;
}
else{
priorOrderIntegrationStatus = order.Order_Integration_Status__c; //For other statuses like Ready, Not Ready, Pending etc.
continue;
}
}
}
if(orderToUpdate <> null && orderToUpdate.size() > 0){
Database.update(orderToUpdate, false);
}
}
global void finish(Database.BatchableContext BC){
System.debug('UpdateOrderIntegrationStatus_Batch Finished');
