Not all code has test suites, most notably:

- code entered at the REPL
- personal automation scripts
- single file Python scripts (as opposed to structured applications)

The tests for these are generally either "Did it do what I wanted?" or
else a dry-run mode where it prints out what it *would* have done in
normal operation.

Cheers,
Nick.
