write a test class for the map?

public class Task14 {
 
    public static void beforeupdate(Map<id,Account> oldmap,Map<id,Account> newmap){
        list<id> accid=new list<id>();
        for(id key:oldmap.keySet()){
            Account old=oldmap.get(key);
            Account newmp=newmap.get(key);
            if(old.Phone!=newmp.Phone){
              accid.add(key);
            }
        }
        list<Contact> con=[select lastname,firstname,phone,accountid from Contact where accountid in:accid];
        for(Contact c:con){
            Account a=newmap.get(c.accountid);
            Account b=oldmap.get(c.accountid);
            c.Phone=a.Phone;
            c.OtherPhone=b.phone;
            
        }
        update con;
    }
}

trigger Task14Trigger on Account (before update) {
    if(trigger.isbefore && trigger.isupdate){
        Task14.beforeupdate(Trigger.oldmap, Trigger.newmap);

Hi Srikant,

Please check once sample code below :
  
@isTest
private class Task14_Test {
    
    @isTest static void beforeupdateTest() {
        Map<id,Account> oldmap = new Map<id,Account>();
        Map<id,Account> newmap = new Map<id,Account>();
        Account acct = new Account(Name='Test Account',phone='123456789');
        insert acct;
        oldmap.put(acct.id, acct);
        
        contact con = new contact();
        con.accountid = acct.id;
        con.LastName = 'TestContact';
        insert con;
        
        
        // Perform test
        Test.startTest();
            acct.Phone = '987654321';
            update acct;        
            newmap.put(acct.id, acct);
            
            Task14.beforeupdate(oldmap,newmap);
        Test.stopTest();        
        
        system.assertEquals('987654321', acct.Phone);
    }
    
}

Hope this helps.

This is not a right approach. As soon as you insert data in your test data, trigger should be fired automatically and coverage should reflect. Hence, instead of step by step covering code approach for trigger, we should follow correct data insertion approach to cover such triggers.

Write A Test Class

 public static void updateOpportunityCity(List<Account> newList, Map<Id,Account> oldMap)
    {
        Map<Id,Account> accIdToMap=new Map<Id,Account>();
        List<Opportunity> OppList=new List<Opportunity>();
        for(Account acc: newList)
        {
            if(oldMap!=null && acc.City__c!=oldMap.get(acc.Id).City__c)
            {
                accIdToMap.put(acc.Id,acc);
            }
        }
        for(Opportunity opp :[Select Id,AccountId,City__c From Opportunity Where AccountId IN :accIdToMap.keySet()])
        {
            
            if(accIdToMap.containsKey(opp.AccountId))
            {
               
                opp.City__c=accIdToMap.get(opp.AccountId).City__c;
                oppList.add(opp);
            }
        }
        if(!oppList.isEmpty())
        {
            update oppList;
        }
    }
