Yes, usually at least once. Part of the reason supercars are so expensive is that the engineering costs are only amortized over a small number of vehicles. The crash test can be considered part of that cost.
The actual incremental cost to produce a supercar is a fraction of the price tag.
In addition to official government crash tests, non-governmental groups such as IIHS also crash test mass market vehicles, but they actually have to purchase the vehicles they test - hoping to make money by selling back the information they collect. It's pretty much never cost effective for IIHS to buy supercars for crash testing.
