I've had this messages 'starred' in gmail for a bit, sorry for replying only now. There's no quick way to describe what the 'functiontest' harness does - I've tried to describe what I understand in the past (see the java/testing/README.htm)...
Maybe if you have specific questions I'll be able to answer better.
The main thing I think that the functiontest harness does is set up all sorts of fun properties for the tests to use, so the same test can run in a number of different ways - in a suite, by itself, with different encryption algorithms, with encoding, locales, frameworks, with
java.sql.DriverManager or instead with DataSource; to run in sequence or separately, start a new database or not...Depending on these properties, more or less 'magic' is done - for example, network server gets started or not, files needed for the test get copied around...
Properties in a suite override properties set for individual tests lower level.
Also, it is able to figure out what jvm is used and add specific (non-standard) properties as needed or applicable.
A big part of it is to control, and eliminate uninteresting differences in the output, but that would be irrelevant with Junit, yes?
Does this help at all?
But maybe that wasn't what Dan meant?
