I again can't comment directly in JIRA as it is unavailable.
I was corrected by Dan on this some time ago, and I have to agree with
him that since the SQLState class is not part of the public API we
shouldn't be relying on it.
I think that if an individual tester wants to use something more
descriptive than "25001" then they can create a constant for the string.
I think it might be worthwhile to create a utility test class that
contains constants for all the SQL States that are currently being
tested against. One could even cut-and-paste from the SQL spec, which
lists all standard SQL states using the following format
INVALID_TRANSACTION_STATE_ACTIVE_SQL_TRANSACTION:
constant SQLSTATE_TYPE :="25001";
and then run some kind of sed script to turn it from their format to
Java, and be good to go, e.g
public static final String
INVALID_TRANSACTION_STATE_ACTIVE_SQL_TRANSACTION = "25001";
I can remove the assertSQLState from the BaseJDBCTestCase. Maybe I'll
get inspired and add the constants file too... :)

Daniel John Debrunner commented on DERBY-1162:
----------------------------------------------
SQLStates are always five characters so I'm not sure why the method needs to
truncate the expected value.
From the comments in the description it seems as though you are expecting tests
should use constants from the engine's SQLState.
That is not good practice, it is not part of the public api and it can lead to
hidden bugs.
If a test is checking for SQLState.SOME_ERROR in a test, then if a error in
coding changes that, say from a SQL Standard 23001 error
to 2E001 then the test will continue to pass, even though a bug was introduced.
Add mechanism to assert/compare SQLStates

Project: Derby
Type: Sub-task
Components: Test
Versions: 10.2.0.0
Environment: JUnit test environment
Reporter: Kristian Waagan

Priority: Minor
Fix For: 10.2.0.0
Attachments: DERBY-1162-1a.diff
The JUnit test environment needs a mechanism to assert/compare SQLStates. The
goal is to be able to reference states from SQLState without having to care if
the length of the identifier is 5,7 or more characters long.
A way to do this already exist in StandardException.getSQLStateFromIdentifier,
but it is too unwieldy and long. I suggest adding 'assertSQLState(String,
String, SQLException)' method to BaseJDBCTestCase.
