COMMENT ON TABLE TestCaseArgs IS
  'Test case argument list variations.

For example, we have a test case that does a set of tests on a virtual
machine.  To get better code/feature coverage of this testcase we wish to
run it with different guest hardware configuration.  The test case may do
the same stuff, but the guest OS as well as the VMM may react differently to
the hardware configurations and uncover issues in the VMM, device emulation
or other places.

Typical hardware variations are:
     - guest memory size (RAM),
     - guest video memory size (VRAM),
     - virtual CPUs / cores / threads,
     - virtual chipset
     - virtual network interface card (NIC)
     - USB 1.1, USB 2.0, no USB

The TM web UI will help the user create a reasonable set of permutations
of these parameters, the user specifies a maximum and the TM uses certain
rules together with random selection to generate the desired number.  The
UI will also help suggest fitting testbox requirements according to the
RAM/VRAM sizes and the virtual CPU counts.  The user may then make
adjustments to the suggestions before commit them.

Alternatively, the user may also enter all the permutations without any
help from the UI.

Note! All test cases has at least one entry in this table, even if it is
empty, because testbox requirements are specified thru this.

Querying the valid parameter lists for a testase this way:
     SELECT * ... WHERE idTestCase = TestCases.idTestCase
                    AND tsExpire     > <when>
                    AND tsEffective <= <when>;

Querying the valid parameter list for the latest generation can be
simplified by just checking tsExpire date:
     SELECT * ... WHERE idTestCase = TestCases.idTestCase
                    AND tsExpire    == TIMESTAMP WITH TIME ZONE ''infinity'';

RTTestCreate, RTTestInitAndCreate and RTTestSub will both create new test
result records, where as RTTestSubDone, RTTestSummaryAndDestroy and
RTTestDestroy will conclude records.

By concluding is meant updating the status.  When the test driver reports
success, we check it against reported results. (paranoia strikes again!)

COMMENT ON TABLE SchedQueues IS

The queues are currently associated with a scheduling group, it could
alternative be changed to hook on to a testbox instead.  It depends on what
kind of scheduling method we prefer.  The former method aims at test case
thruput, making sacrifices in the hardware distribution area.  The latter is
more like the old buildbox style testing, making sure that each test case is
executed on each testbox.

When there are configuration changes, TM will regenerate the scheduling
queue for the affected scheduling groups.  We do not concern ourselves with
trying to continue at the approximately same queue position, we simply take
it from the top.

When a testbox ask for work, we will open a cursor on the queue and take the
first test in the queue that can be executed on that testbox.  The test will
be moved to the end of the queue (getting a new item_id).

If a test is manually changed to the head of the queue, the item will get a
item_id which is 1 lower than the head of the queue.  Unless someone does
this a couple of billion times, we shouldn''t have any trouble running out of
number space. :-)

Manually moving a test to the end of the queue is easy, just get a new
''item_id''.
