Hello I have written test class for following apex trigger. But it is giving an error. Can anyone help me with the same?

Trigger
 

trigger AccountTrigger on Account (after insert, after update, before insert, before update) {
    if(Trigger.isAfter){
        if(Trigger.isInsert){
            AccountTrigger_Helper obj_AccountTrigger_Helper = new AccountTrigger_Helper();
            obj_AccountTrigger_Helper.getGeoLocation(Trigger.new);
        }
    }
 if(System.IsBatch() == false && System.isFuture() == false){ 
  if(Trigger.isAfter){
        if(Trigger.isupdate){
            AccountTrigger_Helper obj_AccountTrigger_Helper = new AccountTrigger_Helper();
            obj_AccountTrigger_Helper.getGeoLocation(Trigger.new);
        }
    }
    }
}

Trigger Handler Apex:
 

global class AccountTrigger_Helper {
    
    public void getGeoLocation(List<Account> listAccountNew){
          getGeoLocationfuture(listAccountNew[0].Id); 
    }
    
    @future (callout=true)
    public static void getGeoLocationfuture(Id AccountId){
        
        //Get all the account records available in salesforce, using Id received in parameter of future method.
        String account_query = 'SELECT id, distance__c, geopointe__Geocode__r.geopointe__Latitude__c, geopointe__Geocode__r.geopointe__Longitude__c, description'; 
                account_query += ' FROM Account WHERE Id != \''+AccountId+'\' LIMIT 10000';
        
        List<Account> accList = database.query(account_query);
        
        //Get Newly inserted Account Record, which fired this trigger, using Id received in parameter of future method.
        List<Account> NewListAccount = [SELECT id,
                                               distance__c,

        Account objAccount = NewListAccount[0];
        
        //geopointe instance
        geopointe.API.DistanceService ds = new geopointe.API.DistanceService();
        
        //Add Newly inserted Account as origin for all instances. and add other accounts as Destination using for loop variable.
        for(Integer i = 0; i < accList.size(); i++){
            ds.add((Double)objAccount.geopointe__Geocode__r.geopointe__Latitude__c,

Test class which I wrote but giving an error:
 

@isTest
private class Test_Account_Trigger {

	    Account acc = new Account(Name='mapAccount');
	    insert acc;
	    
	    for(Integer i = 0; i < 20; i++){
	        Account objAccouont = new Account();
	        objAccouont.Name = 'Test Account '+i;
	       // objAccouont.geopointe__Geocode__c = listGeopointe[i].Id;

}

Please, Help me to solve this error. Thank you.
