hi   can anybody help me to write Test class for this Trigger  and trigger handler class (after update)
custom object(Meeting__c in this checkbox field defult checked) 
scenario:if opportunity stage is 'closed own' or 'closed lost' then meeting__object check box is unchecked

opportunityTrigger
trigger opportunityFactoryTrigger on Opportunity (after update) {
  opportunityFactoryTriggerHandler.doAfterUpdate(trigger.new,trigger.newMap);
    
}

opportunityFactoryTriggerHandler​
public  class opportunityFactoryTriggerHandler {
     public static void doAfterUpdate(List<Opportunity> oppRecList, Map<Id, Opportunity> newMap){
      List<Meeting__c> mettingRecList1 = new List<Meeting__c>();
      List<Meeting__c> meetingRecListToBeUpdated = new List<Meeting__c>();
      mettingRecList1 = [SELECT Id, Opportunity__c FROM Meeting__c WHERE Opportunity__c IN :newMap.keySet()];
