I'm really impressed by test_unit hitting #2. Most people who wander off into ruby bring back their TDD enthusiasm to the other languages they use. That's quite an impact for the entire industry when you think about it. Kudos to all involved for that :)

Thanks! The name's "test/unit", but I won't hold it against you ;-). It's pretty sweet that people have gotten so much mileage out of code I wrote, and if it's helped us as a profession - even a little bit - to write better code, I'm thrilled.

I wouldn't read that much into it. That will get pulled in as a dep for most packages, including Rails.

It's one of the most frequently required libraries in individual files, too. So it's bigger than just being a dependency that's required by rails.

True, but that itself is no small feat.
