It's decision day for BP's new cap on the leaking oil well in the Gulf.

The final pressure and integrity tests are currently underway.

If the cap passes the tests it could remain on the well and possibly keep the oil from flowing out until the relief wells arrive.

That's the best case scenario, but as CNN's Brian Todd warns us, BP still has to tackle some pretty big hurdles.
