    public String selectedcm{get; set;}
    public String tuId;
    
    public callmeetings()
    {
        tuId = ApexPages.currentPage().getParameters().get('tId');        
        cmMap = new Map<Id, Call_Meeting__c>([Select Id, Name, User__c, User__r.Name, Treating_Unit__c from Call_Meeting__c WHERE Treating_Unit__c = null]);
    }
    
    
    public PageReference selectThis() {
        
        if(cmMap.containsKey(selectedcm))
        {
            Call_Meeting__c tempMeeting = cmMap.get(selectedcm);
            tempMeeting.Treating_Unit__c = tuId;
            update tempMeeting;
            return (new PageReference('/'+tuId));
        }
        else
        {
            return null;
        }
    }        
}

Hello as i am new to test classes Could  any one let me know how to write a test class for my utility class that is declared in my trigger.
. the purpose of the below code is we wanted to clone an opportunity with related old opportunity related class

public class treatingDatabaseTrigger_UtilityClass  
{
    public static void treatingDatabase(List<opportunity> newRecord)
    {
        Set<Id> recordTypeIds = new Set<Id>();
        Set<Id> oldOppIds = new Set<Id>();
        recordTypeIds.add(Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get('Child Opportunity').getRecordTypeId());
        recordTypeIds.add(Schema.SObjectType.Opportunity.getRecordTypeInfosByName().get('CA&S Opportunity').getRecordTypeId());
        List<treating__c> insertList = new List<treating__c>();
        for(Opportunity opp : newRecord)
        {
            if((opp.ID__c != null) && (recordTypeIds.contains(opp.RecordTypeId)))
            {
                 oldOppIds.add(opp.ID__c);
            }
        }
        if(!oldOppIds.isEmpty())
        {
            Map<Id, Opportunity> oldOppMap = new Map<Id, Opportunity>([Select Id, (Select Id, Opportunity__c, Treating_Unit__c from Treating_Databases__r) from Opportunity WHERE Id IN :oldOppIds]);
            for(Opportunity opp : newRecord)
            {
                if(oldOppMap.containsKey(opp.ID__c))
                {
                    for(treating__c eachtreating : oldOppMap.get(opp.ID__c).Treating_Databases__r)
                    {
                        treating__c newtreating = new treating__c();
                        newtreating.Treating_Unit__c = eachtreating.Treating_Unit__c;
                        newtreating.Opportunity__c = opp.Id;
                        insertList.add(newtreating);    
                    }
                }
