[TamarZanzouri]

Overview

absorbance reader part of module state update.
https://opentrons.atlassian.net/browse/EXEC-756.
adding missing command unit tests for absorbance reader.

Test Plan and Hands on Testing

upload a protocol using the absorbance reader.
make sure all commands are working as expected.
make sure state is updated as expected.

Changelog

• added state update methods for absorbance reader state.
• added unit test files for absorbance reader commands.

Review requests

1. state update changes make sense? what do you think about having a class for all module state updates?
2. did I miss anything in the tests (I did not implement the commands)? do they make sense?

Risk assessment

low (if I did this properly). module state updates and missing tests.

Looks really good and the porting over to state update passes immediate sight checks for the same kind of behavior we had implemented already. Test coverage also looks good, don't see anything missing there. Thanks for doing this Tamar!

This logic looks solid down through it's usage. We utilize the files added data at the end of a run on the client as when looking through the run result to populate the list of files available for download via the app after the fact, so this should maintain that logic.

Looks great, thank you!

Thank you for filling in the missing tests.

We're still missing tests for ModuleStateStore, but that was the case before, and it certainly doesn't need to get fixed in this PR. It does mean that we have to be careful about reviewing the _handle_absorbance_reader_commands() code by eye, though.

TY!
