Test Class Help for Batch class?

Hi ,
Can you please help me with test class


global class UpdateUnitHighestStageBatchJob implements Database.Batchable<sObject>{
    
    private List<Id> unitIds;

    public UpdateUnitHighestStageBatchJob() {

    }

    public UpdateUnitHighestStageBatchJob(List<Id> parameter) {
        unitIds = parameter;
    }

    global Database.QueryLocator start(Database.BatchableContext context) {
        String soql = 'SELECT Id, Opportunity_Highest_Stage__c FROM Unit__c';
        if (null != unitIds && !unitIds.isEmpty()) {
            soql += ' WHERE Id IN :unitIds';
        }
        return Database.getQueryLocator(soql);
    }
    
    global void execute (Database.BatchableContext context , List<sObject> scope) {
        List<Unit__c> units = (List<Unit__c>) scope;
        Map<Id, Unit__c> units2Update = new Map<Id, Unit__c>();
        for (Unit__c unit: units) {
            List<Unit_Opportunity_Relationship__c> uors = [SELECT Unit__c, Opportunity__r.StageName FROM Unit_Opportunity_Relationship__c 
                        WHERE Unit__c = :unit.Id AND Opportunity__r.StageName != 'Closed Won' AND 
                            Opportunity__r.StageName != 'Closed Lost'];
            String OpportunityHighestStage = 'Z';
            for (Unit_Opportunity_Relationship__c uor : uors) {
                if (OpportunityHighestStage.codePointAt(0) > uor.Opportunity__r.StageName.codePointAt(0)) {
                    OpportunityHighestStage = uor.Opportunity__r.StageName;
                }
              }
              if ('Z' != OpportunityHighestStage) {
                unit.Opportunity_Highest_Stage__c = OpportunityHighestStage;
                units2Update.put(unit.Id, unit);
            }        
        }
        
        if (!units2Update.isEmpty()) {
            update(units2Update.values());    
        }
    }

    global void finish (Database.BatchableContext context) {

    }
}

Try this cod e.. 


ADD ALL required fields to object
