A strange migration tip;

situation.

Have an existing sizeable python repo with embedded /test/folders - hundreds of tests (makes sense, tests are local to the code) - large++ code base

• some test folders have modules, (helpers, utils) but are missing init.py files

• goal: locate all directories under test folders, that don't have init.py files, but do have *.py files,

shellspec and bazel

• goal have bazel run some shell spec testing using shellspec
• caveat won't run on windows (sh_test(..) is not supported there)
• caveat this is not rules_shellspec - though this is close.
• observation shellspec was fussy, but it ran in the end.

This is a comparison of current (May 2021) Rust es-cqrs libraries.

Have used - cqrs-es, exploring all, sticking with cqrs-es. simplicity is nice.

• https://github.com/serverlesstechnology/cqrs-demo

this is also good, but less boiler plate out of the box.
