// TestItemParseStringParse is the big daddy item regression test. We've selected
// a large number of identified items from dumplogs at the alt.org nethack server.
// We do not expect for Parse().String() to match the input string. However, it
// should be the case that any time we parse the stringified version of an Item,
// the resulting item is the same. Any time that doesn't happen, it's a bug and needs
// to be addressed.
//
// The items in this regression test are by no means unique. Once the bot is able
// to play the game, we will begin assembling items it finds into a go-fuzz corpus.
// That corpus will become an exhaustive test of our parsing capabilities.
