Knut Anders Hatlen commented on DERBY-2687:
-------------------------------------------

Looks like a good improvement, I agree. Some small suggestions:

- The method assertFailedStatement() could be replaced by BaseJDBCTestCase.assertStatementError().

- In the catch block of assertFailedBoot(), the search for the SQLState might be expressed more concisely as:

    boolean found = Arrays.asList(accepted).contains(e.getSQLState());

(Or perhaps factor out in a helper method that could be used by other tests? Seems useful enough, and already implemented in RolesConferredPrivilegesTest.assertSQLState().)

- When checking the results of a query that returns a single value, assertSingleValueResultSet() is slightly less verbose than assertFullResultSet().

- Perhaps you could add a comment that explains the purpose of the first line in testEncryption()?
