Cheng Che Chen commented on DERBY-646:
--------------------------------------
I have just emailed scanned images of signed ICLA to [email protected], as
instructed by Kathey Marsden.
Regarding Rick Hillegas' question about the tests included in my patch, there
are three sets of unit tests and one functional test.
The unit tests verify the correctness of my internal data structures. They are
probably not useful to other implementations, unless, for example, they have
similar properties to be verified.
The functional test implements an application in both JAVA and SQL and
cross-checks the computed results. It can indeed be applied to any
implementation of storage factory by simply changing the database name for the
SQL portion of the test object. The functional test consists of the following
files: "GenMog.java", "SampMog.java", "ClusMog.java", "ClusMogSQL.java", and
"MogTest.java" -- the last file is the JUnit test object.
However, I have some doubt about whether I have configured/used Derby's test
framework properly in "MogTest.java". This file started out as a stand-alone
JUnit test. When I was running it stand-alone, it would incur no disk
activity. After I converted the file to run under Derby's test framework, the
disk activity LED on my computer would go wild every time I ran it. I wonder
if I have unwittingly been testing the default storage factory with the
converted test.
