I’ve been playing around with using tape for my tests and I’ve really started to fall in love with it. The default output ain’t that pretty but as the above blog post by Tom MacWright points out all you have to do is pipe it to some other formatter. Thanks to another one of substack’s projects, tap-parser, I’ve actually written two: tap-min and tap-json. There’s also tap-spec and tap-dot, both by Scott Corgan, which I really like too.
