  {
        //First, prepare 200 contacts for the test data
         Account acct = new Account(name='test account');

         insert acct;

         Contact[] contactsToCreate = new Contact[]{};

         for(Integer x=0; x<200;x++)
        {
         Contact ct = new Contact(AccountId=acct.Id,lastname='test');
         contactsToCreate.add(ct);
        }

        //Now insert data causing an contact trigger to fire.

        Test.startTest();

        insert contactsToCreate;

         Test.stopTest();   
     }  
 }
