move all tests to a separate module?

[uwuclxdy]

should the tests be moved from source files to their own module (src/tests/ for example)? i think its a good idea to separate them from the main code. thoughts?

The convention suggested by the Rust book seems to be of unit tests along with source code, and integration tests in their own files.

The rationale seems to be that it's easier to access private functions that way.

Agreed with @lucaspar: we don't have any integration tests currently, and most tests are very module-specific.
