Expose a test suite

[Stargateur]

It would be nice to have a test suite that test an implementation of Buf and BufMut. It's would avoid everybody to write they own test, also, I expect bytes test would be way more exhaustive.

• Having a bytes-test crates ?
• Expose it in bytes ?
• Other solution ?

This is a pretty decent idea. It's kind of like the "contracts" you may find in Scala/Haskell, where after you implement a typeclass, you can check to make sure you followed all the expected properties. I suppose a next step would be a formal proposal of all that it would check?

I'm not sure it's necessary, that may be ask too much. Just a entry api that say "look ok" would be amazing the next level would be "not ok here what doesn't work" like named test.

My motivation is for circbuf that implement a circular buffer that I use for tokio. I just have the idea to have more solid test than https://github.com/jeromefroe/circbuf-rs/blob/master/src/lib.rs#L959
