Please help me to write test classes for the following trigger

Hi,

I tried some code, but it is not working.

/Trigger to Count the Number of Attachments on an Object

trigger countattachment on Attachment (after insert, after update, after delete, after undelete) {
  Map<Id,List<Attachment>> parent = new Map<Id,List<Attachment>>();
  set<id> attids = new set<id>();
     
   if(Trigger.new<>null){
       for(Attachment c:Trigger.new){
           MDF__c l;
           if(c.ParentId != null)
               attids.add(c.parentid);
       }
           
   }else if(Trigger.old != null){
       for(Attachment c:Trigger.old){
           if(c.ParentId<>null)      
               attids.add(Trigger.oldMap.get(c.id).parentid);
       }
   }
   if(attids.size()>0){
       try{
           List<Attachment> a = new List<Attachment>();
           Map<id,MDF__c> testmap = new Map<id,MDF__c>([select id,CountAttachment__c from MDF__c where id IN: attids]);
           a = [select id,parentid from Attachment where parentid IN:attids];
           
           for(Attachment at: a){
               List<Attachment> llist = new List<Attachment>();
               if(parent.get(at.parentid) == null){
                   llist = new List<Attachment>();
                   llist.add(at);
                   parent.put(at.parentid,llist);
               }else if(parent.get(at.parentid) != null){
                   llist = new List<Attachment>();
                   llist = parent.get(at.parentid);
                   llist.add(at);
                   parent.put(at.parentid,llist);
               }
           }
           
           for(Id i: attids){
               if(testmap.get(i) != null && parent.get(i) != null){
                  testmap.get(i).CountAttachment__c = parent.get(i).size(); 
               
               }else if(testmap.get(i) != null && parent.get(i) == null){
                  testmap.get(i).CountAttachment__c = 0; 
               }
           }
       
           update testmap.values();
           System.Debug(testmap.values());
       }catch(Exception e){}
    }

}

@isTest
public class countattachmenttest{
    Private Static testmethod void countattachmenttest(){ 
        MDF__C m = new MDF__C();
        m.Name='Test';
        m.Amount__c=500;
        insert m;


        Attachment attach=new Attachment(); 
        attach.Name='Unit Test Attachment'; 
        Blob bodyBlob=Blob.valueOf('Unit Test Attachment Body'); 
        attach.body=bodyBlob; 
        attach.parentId=m.id;
        insert attach; 



Attachment attach1 =new Attachment(); 
        attach1.Name = 'Unit Test Attachment'; 
        Blob bodyBlob1 = Blob.valueOf('Unit Test Attachment Body'); 
        attach1.body = bodyBlob; 
        attach1.parentId=m.id;
        insert attach1; 



   Update  attach; 

upadte attach1;


Delete attach;  

Delete  attach1; // if you are not able to get 75 add undelete 



      


      //  List<Attachment> attachments=[select id, name from Attachment where parent.id=:m.id]; 
        System.assertEquals(1, attachments.size());
