Subject [jira] Commented: (DERBY-796) jdbc 4.0 specific Blob and Clob method support
Date Tue, 14 Feb 2006 20:47:11 GMT
    [ http://issues.apache.org/jira/browse/DERBY-796?page=comments#action_12366380 ] 

Daniel John Debrunner commented on DERBY-796:
---------------------------------------------

The embedded changes look good.

Is there any reason for the changes in the TestConnection.java class, such as database name
from mydb to mydb1?
And is there any good reason for this class, why don't these tests get the connections the
standard way, used by all
other tests in the harness?

I see this pattern in the tests for failed exceptions:

+            catch(IOException ioe) {
+                System.out.println("Input output exception occurred" + ioe);
+            }
+            catch(SQLException sqle) {
+                System.out.println("SQLException occurred" + sqle);
+            }

I guess it's not critical but this approach to displaying errors is a real pain when you actually
hit a failure.

Just printing what you print means that on a failure, I have to find which line was causing
the error,
not easy if one uses the same text like "SQLException occurred", modify  that code to print
the stack trace,
modify the code to print the SQLException chain, and then re-run the test.

Printing the stack trace, and for SQLExceptions the complete nested chain and their stack
traces can often
mean spotting what the problem is instantly.
