Need some help, i'm in over my head.  I've got a custom field on a custom object and have the following apex running on a trigger.  I don't know how or what would be the best way to execute this field update automatically.  On one hand it would be great to exeute the trigger every night at midnight, as i will be duplicatingt he field and query for each month.  Any help or a point in the right direction would be great.

trigger WonNov on Course__c (before update) {

    Set<Id> setRecordId = new Set<Id>();
    
    for (Course__c obj : Trigger.new)
    {
        setRecordId.add(obj.id) ;
    }
    
    AggregateResult[] groupedResults = [ Select SUM (Amount) sum, Course_Lookup__c from Opportunity WHERE Courseid__c in :setRecordId AND Opportunity_Type__c ='Outing' AND Probability >94.00 AND Event_Date__c = THIS_YEAR AND Event_Month__c = '11_November' GROUP BY Course_Lookup__c ];
    
    Map<String , AggregateResult > mapAG = new Map<String , AggregateResult >();
    for(AggregateResult ar : groupedResults)
    {
        mapAG.put(String.valueOf(ar.get('Course_Lookup__c')) , ar );
    }
    
    for (Course__c obj : Trigger.new)
    {
    
        if( mapAG.containsKey(obj.id) )
        {
            AggregateResult ar = mapAG.get(obj.id);
            double sum =double.valueOf(ar.get('sum'));
            obj.Won_Nov_Outings__c = decimal.valueOf(sum);
            
        }
    }
}

I have the following Apex Class and Trigger. I'm struggling to come up with a Test Class to test. Can someone please point me in the right direction. 

public class WebServiceCallout {

    @future (callout=true)
    public static void sendNotification(String name, String planId) {

        HttpRequest req = new HttpRequest();
        HttpResponse res = new HttpResponse();
        Http http = new Http();
        System.debug('String Name'+name);
        System.debug('String Id'+planId);
        req.setEndpoint('https://devl-armadahealthdss.armadahealth.com/api/armadahealthdss/token/single');
        req.setMethod('GET');
        req.setBody('name='+EncodingUtil.urlEncode(name, 'UTF-8')+'&planId='+EncodingUtil.urlEncode(planId, 'UTF-8'));
        req.setCompressed(true); // otherwise we hit a limit of 32000

        try {
            res = http.send(req);
            System.debug(res.toString());
            System.debug('Response'+res);
            Map<string,Object> mapbody=(Map<string,Object>)JSON.deserializeUntyped(res.getbody());
            System.debug('Token'+(Integer)mapbody.get('token'));
            Integer Token = (Integer)mapbody.get('token');
            plan__c plan = [Select Id from Plan__c where Id =: planId];
            plan.registration_code__c = string.valueof(Token);
            System.debug('Reg Code'+plan.registration_code__c);
            update plan;            
        } catch(System.CalloutException e) {
            System.debug('Callout error: '+ e);
            System.debug(res.toString());
        }

    }

    // run WebServiceCallout.testMe(); from Execute Anonymous to test
    //public static testMethod void testMe() {
      // WebServiceCallout.sendNotification('My Test Customer','My City');
    }

 

trigger PlanCallToken on Plan__c (after insert) {

    for (Plan__c a : Trigger.new) {           
         // make the asynchronous web service callout 
         if(!system.isFuture() ){             
         WebServiceCallout.sendNotification(a.Name, a.Id);                
         }
    }
