Class

public with sharing class updateAcDescTriggerHandler{
    
    public static void updateAcDesc(Set<Id> setAcIds){
        
        List<Account> acList = [SELECT Id, Description
                         FROM Account

}

Trigger

trigger pdateAcDescTrigger on Account (after insert, after update) {
    if(trigger.isAfter){
        if(trigger.isInsert){
            updateAcDescTriggerHandler.updateAcDesc(Trigger.newMap.keySet());
            }
    }

}

Test Class

@isTest

    @isTest
    private static void testMethodA(){
        Account ac1 = new Account();
        ac1.name='New Account for Future Method';
        ac1.Description='Methods with future annotation must be static';

        ac2.Description='Methods with future annotation must be static';
        
        List<Account> acList = new List<Account>{ac1, ac2};            
        insert acList;
        Set<Id> acIds = new Set<Id>{ac1.id,ac2.Id};
        
        Test.startTest();
        updateAcDescTriggerHandler.updateAcDesc(acIds);
        Test.stopTest();
