I am trying to create a batch Apex class that I can schedule to run weekly to automatically unqualify Leads that are 60 days old or older and haven't had activity on them in the past 10 days (and only for a single Record Type). Here is my Class and Test Class...I keep receiving a "Methods defined as TestMethod do not support Web service callouts." My test class doesn't include any callouts..but I know we have a trigger or two in our instance on Leads that does have a callout. How do I fix my test class then?

Batch Apex Class:

global class AutoUnqualifyLeads implements Database.Batchable<sObject> {
   
    global Database.QueryLocator start(Database.BatchableContext bc){
        String query = 'SELECT Id, Status, Reason_Not_Qualified__c, LastActivityDate '+
                         'FROM Lead '+
                        'WHERE CreatedDate < LAST_N_DAYS:60 '+
                          'AND Days_Since_Last_Activity__c > 10 '+
                          'AND IsConverted = false '+
                          'AND Status != '+' \'Unqualified\' '+
                          'AND RecordTypeId = '+' \'01270000000Q4tB\' ';
        return Database.getQueryLocator(query);
    }
    
    global void execute(Database.BatchableContext bc, List<Lead> scope){
        List<Lead> leads = new List<Lead>();
        for (Lead l: scope){
                l.Status                  = 'Unqualified';
                l.Reason_Not_Qualified__c = 'No Response';
                system.debug(l);
                leads.add(l);
        }
   update leads;
   }

    global void finish(Database.BatchableContext bc){
        
    }
}

Test Class (my test load data information is listed below the code snippet):

@isTest
public class AutoUnqualifyLeadsTest{
        
    @testSetup
    static void setupTest(){
        List<Lead> leadLoad = Test.loadData(Lead.sObjectType,'testLeadsAutoUnqual');
        System.debug(leadLoad);
        
        Lead L1 = (Lead)leadLoad[0];
        
        List<Task> tasks = new List<Task>();
         Task t = new Task();
           t.Subject = 'Test';
           t.Status = 'Completed';
           t.ActivityDate = Date.newInstance(2017, 10, 09);
           t.WhoId = L1.Id;
           System.debug('WhoId = '+t.WhoId);
         tasks.add(t);
         insert tasks;
        
        L1.Status = 'Contacted';
        Update L1;
             
        List<Lead> days = [Select Days_Since_Last_Activity__c, Status, FirstName 
                             From Lead
                            Where Id = :leadLoad];
        System.debug(days);
        
        
    }

    @isTest
    static void testLeads(){
        
        Test.startTest();
        AutoUnqualifyLeads aul = new AutoUnqualifyLeads();
        Id batchId = Database.executeBatch(aul);
        Test.stopTest();
        
     //after the testing stops, assert records were updated properly
     System.assertEquals(1, [select count() from Lead where Reason_Not_Qualified__c='No Response']);
    }
 
}

Test data:

CreatedDate, RecordTypeID, Days_Since_Last_Activity__c, Status, Reason_Not_Qualified__c, LastName, Company
