Whence eunit:test/0?

[Brujo Benavides]

It’s the magic of parse transforms!

eunit.erl includes eunit.hrl: https://github.com/erlang/otp/blob/8e4abc44d58e61753716e63b23c6b44d221feb15/lib/eunit/src/eunit.erl#L30 <https://github.com/erlang/otp/blob/8e4abc44d58e61753716e63b23c6b44d221feb15/lib/eunit/src/eunit.erl#L30>

When you include that header file, it will create a test/0 function for you.
