Salesforce Test Class Failed when I want to validate in the production

I am beginner in salesforce APEX coding. Currently I am trying to make a scheduler for my org where i want to update my ManagerID form the UserRole.

In my testing ORG this code is showing 93% of code coverage but when I want to deploy in the production, The code coverage is only 67%. Can anybody help me with the below code:

AstroUpdateManagerID

public class AstroUpdateManagerID{
public List<UserRole> UserRoleList1(){
    List<UserRole> userRole = new List<UserRole>();
    userRole= [select Id, Name, ParentRoleId from UserRole];
    return userRole;
}



List <UserRole> role =UserRoleList1();

Map <Id, User> userParentMap = new Map <Id, User>();
Map <Id, UserRole> userRoleMap = new Map <Id, UserRole>();




public User HandleParentNull(UserRole userroleobj){
        User userobj = new User();
        userobj  = userParentMap.get(userroleobj.ParentRoleId);
        if(userobj == null ){
            UserRole userRole2 = userRoleMap.get(userroleobj.ParentRoleId);
               userobj = HandleParentNull(userRole2);
        }
return userobj;

}




public String get_Manager_ID_Where_Partner_Owner_Is_NA(User u){
                UserRole userRoleOBJ = userRoleMap.get(u.UserRoleId);
                return HandleParentNull(userRoleOBJ).Id;
}



public List<User> UserIdentification(List<User> user){


List<User> AllUserList = new List<User>();

        //Find User role by UserRole.Id
        for(UserRole ur: role){
            userRoleMap.put(ur.Id, ur);
        }


             //Find user by User.UserRoleId
            for(User userparent: user){
            userParentMap.put(userparent.UserRoleId, userparent);
        }

    for (User u: user){
        if(u.Partner_User_Owner__c != 'NA'  && u.UserRole.Name != 'Director of Sales' && u.Profile.Name != 'System Administrator'){
                u.ManagerId = u.Partner_User_Owner__c;
                AllUserList.add(u);
            }else if(u.UserRole.Name != 'Director of Sales'  && u.Profile.Name != 'System Administrator'){
                        u.ManagerId =   get_Manager_ID_Where_Partner_Owner_Is_NA(u);
                        AllUserList.add(u);
                    }
