Depends on what you want to test. It could be as simple as a 9V battery,
a pushbutton, two resistors and a led.
Yeah, but let's be fair. These IGBTs are usually heavy duty, high
current devices. A serious test is going to need a bit more current
than a 9V battery can supply. OTOH, if the pulse duty cycle is very
low, it might be possible. But the gate driving circuitry is probably
going to need more than a 9V battery.
I would start looking at various datasheets, see what looks as the
most interesting aspects of a IGBT, and then decide what needs to
be tested/measured/verified and estimate what can be done in the
time available for this project.
If you need inspiration, here's what seems a nice tester:

Jeez, 3000V at 2000 A (cough-cough!) Requires 230VAC at 16A! Just
the shipping alone will cost a whole lotta money! Whew!
Like, here's a piece of equipment that takes more juice than the whole
average home uses. Nice to plan ahead to make sure you can afford the
electric bill. Remember those Startrek episodes where they had to
make a choice between weapons and life support? Cap'n says Fire! and
we hear the 'PLOINK!' in the background and all the lights go dim.
COOL! Just testing another IGBT..
