How to get code coverage on apex trigger

Here's the code, not sure why it's not working when I've deployed it before... 

trigger UpdateAccountName on Task (before update)
{ 
    Map<Id, Task> idAccountTaskMap = new Map<Id, Task>();
    for (Task t : Trigger.new) {

        if(t.AccountId != null)
            idAccountTaskMap.put(t.AccountId, t);
    }

    if(idAccountTaskMap.isEmpty()) return;

    Map<Id, Account> accountMap = new Map<Id, Account>([SELECT Name FROM Account WHERE Id = :idAccountTaskMap.keyset()]);

    for(Task a : idAccountTaskMap.values())
    {  
        a.Account_Name__c = accountMap.get(a.AccountId).Name;
    }
}

Hi,

I have written the test class with 100% code coverage. 

<<<<----Apex Trigger---->>>>
  
trigger UpdateAccountName on Task (before update)
{ 
    Map<Id, Task> idAccountTaskMap = new Map<Id, Task>();
    for (Task t : Trigger.new) {

        if(t.AccountId != null)
            idAccountTaskMap.put(t.AccountId, t);
    }

    if(idAccountTaskMap.isEmpty()) return;

    Map<Id, Account> accountMap = new Map<Id, Account>([SELECT Name FROM Account WHERE Id = :idAccountTaskMap.keyset()]);

    for(Task a : idAccountTaskMap.values())
    {  
        a.Account_Name__c = accountMap.get(a.AccountId).Name;
    }
}


<<<<----Test Class---->>>>
  
@isTest
private class CreateTask {
    
    @isTest static void createTask1(){
        
        Account accObject = new Account();
        accObject.Name = 'TASK';
        Insert accObject;
        
        Task taskobject = new Task();
        taskobject.WhatID = accObject.id;
        taskobject.Subject = 'subject';
        Insert taskobject;
        System.debug('taskobject-->>'+taskobject);
        taskobject.Subject = 'subject1';
        Update taskobject;
    }
}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
