Hi 
I have an issue with a batch class which updates the custome field as Active, Inactive or frozen. Its is working fine but test class is failing for this.

Could someone help with this

Batch Class:

global class UserUpdateBatch implements Database.Batchable<sObject> {

    Public String query;

    global Database.QueryLocator start(Database.BatchableContext BC) {
       //if(!Test.isRunningTest()){
        query = 'SELECT Id, isActive, Status__c FROM User'+(Test.isRunningTest()?' LIMIT 200':'');
      //}  
        return Database.getQueryLocator(query);
    }

    global void execute(Database.BatchableContext BC, List<User> scope) {    
        List<Id> usrLogLst = new List<Id>();
        for(UserLogin ul : [SELECT UserId, isFrozen from UserLogin where isFrozen = true and UserId IN: scope]){
            usrLogLst.add(ul.userid);
        }
        
        for(User usr : scope){
            if(usrLogLst.contains(usr.id)){
                usr.status__c = 'Frozen';
            }
            else{
                if(usr.isActive==true){
                    usr.status__c = 'Active';
                }
                else{
                    usr.status__c = 'Inactive';
                }
            }
        }

        Database.SaveResult [] updateResult = Database.update(scope, false);
        
        for (Database.SaveResult r : updateResult)
        
        {
            if (!r.isSuccess()) 
            {
                for (Database.Error e : r.getErrors())
            { system.debug('Error'+e); }
            
            }
        
        }
               update scope;
    }

    global void finish(Database.BatchableContext BC) {
    }
}
