How many test subsystem is good for a company

How many test subsystem is good for a company
The company I work for has three test subsystems (unit, system and
quality). Most of the application developers test their programs in the
unit and quality subsystems and then prompt their program to the
production subsystem. The system subsystem is rarley used. I am just
wondering how many test subsystems each of you have. Is the company I
work for has too many test subsystems ?

Best Regards,
Mark

In our shop we have 1 unit test subsystem and 4 user's acceptance
subsystems. Always we asked for more test subsystems in order different
applications do their tests

Be glad you've got 3 test subsystems, one rarely used. Here we've got
different test subsystems for left-handed and right-handed mouseclickers.
Setting them up and keeping them running is the major part of DBA work
here (the second major part is moving databases to different servers).
That's Oracle for you. I personally only ever used one integrated
Dev/Test-environment for the things I developed...

Re: How many test subsystem is good for a company
(in response to Jeff Frazier)
Mark

In my opinion we have far too much test subsystems. We've got one rarely
used system subsystem. This is o.k. because the sysprog guys first test
here, if there are big changes to the DB2 system itself. Then we've got a
test subsystem, where application programmers test their new are changed
code. The next one - and sorry I lack the rigth English expressions - say
unit test subsystem (the next endevor stage). The next one is - hm - let's
call it overall test subsystem (the next higher endevor stage), then a
preproduction subsystem and last but not least a production subsystem.
At the moment the is a big project running, so we cloned our production
system and for regression test, we've got another one.
To make things more complex, in the various test-systems most tables have
copies of theirselves with different qualifiers, some up to 30.
So you can imagine. if we have to make a change to a table structure, how
many work we have ahead.

Re: How many test subsystem is good for a company
(in response to Walter Janißen)
Hi Mark,

A couple of years ago we had one DB2 and one IMS subsystem in development.
These were used for unit, system and acceptance testing with different
named databases, transactions etc for each testing level within the
subsystems. In production we have 4 DB2 subsystems and 2 IMS
subsystems.

For a number of reasons we split up the development subsystems so we had a
configuration which looked like production at each level, therefore 12
development DB2 subsystems and 6 IMS subsystems. It has been a lot of
work mainly due to the application changes required but very worthwhile,
although many of the key issues we were addressing may not be issues that
you have.

Jim.
