They work if these tests are run individually. However, when I run the
class, they fail, since the TC#1 already created the user jdandy.
So, how can I call this batch file in between each TC, with the batch file
completing before starting TC#2?
You might consider making a direct database

Bret,
I had a look long ago at Piotr Kaluski's very detailed docs for Perl's
Win32GuiTest
(http://www.piotrkaluski.com/files/winguitest/docs/winguitest.html).
He even lists some C code examples. I'm afraid C is a little beyond
me...

Thanks for taking the time to look at this. If you are referring to
Ruby/OCI8 for Oracle, yes I already have that installed. Any other ideas as
to how to get this fixed?
Clearly you *don't* have it installed, or else it's installed
improperly. The message custom_require.rb:27:in

I read this yesterday, I was kind of surprised to find it coming from
a TW developer. This is *so* not unit-testing!

r = weights.inject(0){|s,x|s+x} * rand
weights.inject(0) {|s,x| s+=x; return x if s=r;s}
weights[-1]
end

stat.default=0

One major drawback for this is that it won't work out of the box for
values like calc([0.1,0.1,0.8]) That is, call def a 10% of the time,
def b 10% of the time, def c 80% of the time. It seems input values
have to be unique.
Here's something that does the job, but I can't help thinking
