Usually I would do this in a lib.rs
extern some_crate pub mod some_submodule;
Then in a separate file; some_submodule.rs, I could do this
Can’t seem to get the same thing working in a tests/ directory for my crate. Cargo test requires me to put
extern some_crate in each and every test file. I want them all to share a common imported namespace. Furthermore, I can’t seem to figure out how to
use a module in separate file in the tests directory. The compiler wants me to
extern crate any file I try to use from another file.
