Subject Re: [jira] Commented: (DERBY-1162) Add mechanism to assert/compare SQLStates
Date Wed, 29 Mar 2006 17:40:09 GMT
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

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 

I can remove the assertSQLState from the BaseJDBCTestCase.  Maybe I'll 
get inspired and add the constants file too... :)

>>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.
