Doing otherwise would make life harder (e.g. how do you establish if a test failure is expected with a given src version) for no good reason. I suspect we may be working with different views of what a test tool does here. You may be thinking more along the lines of something like iperf, while I’m thinking more of test like this one: https://cgit.freebsd.org/src/commit?id=4c84c69ba308b7758d07dc8845b13922ed667e02 I’ll take the opportunity to point out that there’s precedent for using non-base languages in tests (e.g. Python, for the test linked above), so using Rust code for in-tree tests looks like a reasonable way to get our toes wet, without immediately painting ourselves into a corner if it doesn’t work out. — Kristof
