Spork is Tim Harper’s implementation of test server\nSpork runs on POSIX systems using fork. It also runs on windows by pre-populating a pool of ready processes (referred to here as the “magazine” strategy).\nGuard is a command line tool that easily handle events on files modifications.\n\n
Why still 3 seconds? Because there are still some things we reload on every run of specs (although this can be probably optimized).\nBesides this, you also save time by not having to run specs manually. So guard-rspec is relevant even if you don't have a big Rails project or non Rails project at all.\n\n
