Yes, for a long while – I believe it's fairly widely used (and it's absolutely excellent!)

I somehow tried to make sense of the name as a superlative form of "next". Perhaps next-test would have been fine?

Thanks for posting about this! I'm the main author of nextest, and it represents my best foot forward for how Rust testing should be done. Happy to answer questions though I might be a bit intermittent.

That is indeed the pun =)

Yes, been using it for 18’ish months. Works great.

I love nextest, it's been great. This along with bacon catches a lot of issues.

Big fan of nextest and this is my first time seeing this site. I'll be real I feel a bit ridiculous commenting this but you might want to consider rephrasing this:

>Treat tests as cattle, not pets. Detect and terminate slow tests.

Not sure saying, "hey, treat your tests as an animal you can kill at will" paints the right image.
