Another way to find/remove duplicate rows is:

SELECT test_id
  FROM test t
 WHERE t.rowid >
(SELECT MIN(t1.rowid)

     FROM test t1
    WHERE t.test_id=t1.test_id);

Then, if you wanted to get rid of the dups, just DELETE: DELETE FROM test t
WHERE t.rowid >
(SELECT MIN(t1.rowid)

     FROM test t1
    WHERE t.test_id=t1.test_id);
