Please add an empty file under tests called __init__.py. It's a standard-if-weird thing that code directories require for python module loading infrastructure to work correctly. For example:

❯ python -m unittest

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

❯ touch tests/__init__.py

❯ python -m unittest
.........
----------------------------------------------------------------------
Ran 9 tests in 4.786s

OK

❯ ls -l tests/__init__.py
-rw-r--r--  1 dlchudnov  staff  0 Apr 29 12:08 tests/__init__.py

Without the __init__.py file present, the autodiscovery function in the unittest module won't find the test scripts. By creating it, even as an empty file (via touch on macos/unix), it triggers the autodiscovery to look into that directory for tests.

Minor changes as noted in comments. Otherwise, works for me... glad to see this coming together!

The tests look good! Found some other issues, but this is good to go.
