[Improvement] Initial build fails due to test

[daniel-deychakiwsky]

If I clone the cookie cutter and upload it as is, the build failed. This has to do with the testing directory. I added atest_noop.py unit test and then it all worked. Maybe include this in the initial template for a clean build?

def test_noop() -> None:
    assert True

I noticed this as well, but I was wondering whether adding a dummy test file would propagate to all packages when running cruft update.
