Integration tests can't find crate

[OrangeTux]

This is not a bug in PyO3, but it can hit Pyo3 users nonetheless.

I'm using PyO3 for a project and wrote some integration tests. I put those tests inside a tests/ directory at the crate root. However my tests fail to compile because my crate couldn't be found:

 error[E0463]: can't find crate for `yolo`
   --> tests/tests.rs:4:1
    |
  4 | use yolo;
    | ^^^^^^^^^ can't find crate

It turns out that cdylib crate types can't use tests inside a tests/ directory. See rust-lang/cargo#6659

I think this should be documented, as this is not very obvious. What would be the best place to do that? Inside the FAQ?

Inside the FAQ?

Yeah, I think FAQ & Troubleshooting is good and am really appriciate your PR.

[OrangeTux]

Happy holidays!
