how do i write test class for the method that accepts list of record ids.

This is my method : 
public static List<String> UpdateStatus(List<String> recordId ){
        //Fetch the current values in sub status multiselect picklist
        GPO_Rebate_Payment__c gpopayment = [SELECT Sub_Status__c,Status__c FROM GPO_Rebate_Payment__c where id IN :recordId LIMIT 1];
         List<String> currentStatusValues = gpopayment.Sub_Status__c.split(';');
        
        If(gpopayment.Status__c == 'Pharma Payment')
        {
            if(!currentStatusValues.Contains('Overdue'))
            {
                 currentStatusValues.add('Overdue');
            }
        }
        else{
            if(currentStatusValues.Contains('Overdue'))
            {     
                for(Integer i = currentStatusValues.size() - 1; i >= 0; i--) {
                if(currentStatusValues[i].equals('Overdue')) 
                {
                currentStatusValues.remove(i);
                }
    }
                 //currentStatusValues.('Overdue');
            }
        /* String newStatusValues;
        newStatusValues = string.join(currentStatusValues ,';');
         gpopayment.Sub_Status__c = newStatusValues;*/
    
    }
        return currentStatusValues;

}

i have written this test method but it is giving me error of illegal assignment from List to List: 
@isTest
    public static void UpdateStatusTest(){
        GPO_Rebate_Payment__c gpopayment = new GPO_Rebate_Payment__c();
        gpopayment.name = 'test class';
        gpopayment.Status__c = 'Pharma Payment';
        gpopayment.Sub_Status__c = 'In Progress';
        
        update gpopayment;
        
        test.startTest();
        List<String> recid = [SELECT Id FROM GPO_Rebate_Payment__c WHERE name='test class'];
        GPORebatePaymentSubStatusUpdate.UpdateStatusTest(recid.Id);
        test.stopTest();

Please use below code:-

        gpopayment.Status__c = 'Pharma Payment';
        gpopayment.Sub_Status__c = 'In Progress';
        
        update gpopayment;

List<String> recList = new List<String>(); 
List<GPO_Rebate_Payment__c> recids = [SELECT Id FROM GPO_Rebate_Payment__c WHERE name='test class']; 
  for(GPO_Rebate_Payment__c rec : recids){ 
    recList.add(rec.Id); 
   }
        test.startTest();

Hi Hitesh,

try with below code. 
@isTest
    public static void UpdateStatusTest(){
        GPO_Rebate_Payment__c gpopayment = new GPO_Rebate_Payment__c();
        gpopayment.name = 'test class';
        gpopayment.Status__c = 'Pharma Payment';
        gpopayment.Sub_Status__c = 'In Progress';
        
        insert gpopayment;

List<String> recList = new List<String>(); 
List<GPO_Rebate_Payment__c> recids = [SELECT Id FROM GPO_Rebate_Payment__c WHERE name='test class']; 
  for(GPO_Rebate_Payment__c rec : recids){ 
    recList.add(rec.Id); 
   }
        test.startTest();
		GPORebatePaymentSubStatusUpdate.UpdateStatus(recList);
        test.stopTest();
		}
If this helps, Please mark it as best answer.

Thanks!!

How will i cover the ELSE condition logic of the method ? create a new record with the condition that fulfills the else condition ?
AnkaiahAnkaiah (Salesforce Developers) 
Create another Test method which should meet the else condition.
  
@isTest
    public static void UpdateStatusTest1(){
        GPO_Rebate_Payment__c gpopayment = new GPO_Rebate_Payment__c();
        gpopayment.name = 'test class';
        gpopayment.Status__c = 'Overdue';
        gpopayment.Sub_Status__c = 'In Progress';
        
        update gpopayment;

List<String> recList = new List<String>(); 
List<GPO_Rebate_Payment__c> recids = [SELECT Id FROM GPO_Rebate_Payment__c WHERE name='test class']; 
  for(GPO_Rebate_Payment__c rec : recids){ 
    recList.add(rec.Id); 
   }
        test.startTest();
		GPORebatePaymentSubStatusUpdate.UpdateStatus(recList);
        test.stopTest();
		}

If this helps, Please ,mark it as best answer.

Thanks!!
