Test Class for Inbound Email Service

I have written following inbound email service for lead object
global class LeadServices implements Messaging.InboundEmailHandler
{
global Messaging.InboundEmailResult handleInboundEmail(Messaging.inboundEmail email, Messaging.InboundEnvelope env)
{
Messaging.InboundEmailResult result = new  Messaging.InboundEmailResult();
string emailbody = email.plaintextbody;
string emailsubject = email.subject;
string subToCompare = emailsubject.Substring(emailsubject.indexof('ref :') + 5).trim();
try
{
lead l = [SELECT  Id, Name,Email FROM  lead WHERE id = : subToCompare];
Task newTask = new  Task();

newTask.Description = emailbody;
newTask.Priority = 'Normal';
newTask.Status = 'Inbound Email';
newTask.Subject = emailsubject;
newTask.IsReminderSet = true;
newTask.ReminderDateTime = System.now();
newTask.WhoId = l.Id;
Insert newTask;
}
catch(QueryException e)
{
System.debug('Issue: ' + e);
}
result.success = true;
return result;
}
}
I am have having 55% code coverage now.
Can someone please hepl me with test class for this?
