Would you be writing tests for a single purpose module?

Dear Bod, we've discussed this topic before, on April 1 2021 - where my answer was not intended as an April Fools' joke. In summary:

You should write your tests before you write your module - or while you are developing it
This is because the act of writing the tests improves the module's design, especially its interface.
