[erlang-questions] Unit testing code - whence?

[Jon Watte]

Unit tests in a different module means you have to open your module up a lot
more than if the tests are in the same module.

Generally, I write the code, then I include_lib eunit.hrl, then I write the
unit tests. That can all be wrapped in conditional compilation if you need
to. However, when just developing new functions, I typically put the tests
right by the functions they're testing, and only when I'm done do I move
them to the end of the file.

Works for me/us! Your mileage may vary.

Sincerely,

jw
