One integration test should be to take the engineer in charge, bind one arm behind his back and tell him to make Spaghetti aglio olio peperoncini for Gordon Ramsey waiting with a Santoku knife ready for some action.

Edit: To clarify - Aglio olio is what they cook in prison in Good Fellas. It's both the most simplest pasta dish and the easiest to screw up - overcook the garlic a bit and you get garlic chips instead of melting their flavour into the sauce.
