How to implement test class for the given controller

Hello Folks, 

I am new to salesforce development. Attempting to write a test class for below code. Please suggest.
 

public class CountContactHandler {
    
    public static void ContactCheckBox(List<Contact> con) {
        
        Set<Id> setid = new Set<Id>();
        for(Contact c : con) {
            setid.add(c.AccountId);
        }
        
        List<Account> acc1 = [SELECT Id, Name From Account WHERE Id In :setid];
        
        for(Account a1 : acc1) {
            
        }
    }

}

Hi Kunal,

This apex class seems to be incomplete. But below test class covers 100% . If you share the trigger as well so it may cover both.
  
@istest
public class CountContactHandlerTest {
@isTest static void testconcount() {
    
    Account acc= new Account();
    acc.name= 'sample account';
    insert acc;
    
    Contact con= new Contact();
    con.lastname='sample cpontact';
    con.AccountId=acc.id;
    insert con;
    List<Contact> conlist= new List<Contact>();
    conlist.add(con);
    CountContactHandler.ContactCheckBox(conlist);
}
}

Let me know if you face any issues.

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

Thanks,
