[braingram]

Add romancal unit tests to the CI (similar to the roman_datamodels tests).

Tasks

• Update or add relevant rad tests.
• Update relevant docstrings and / or docs/ page.
• Does this PR change any schema files?
  • Schema changes were discussed at RAD Review Board meeting.
• Does this PR change any API used downstream? (If not, label with no-changelog-entry-needed.)
  • Write news fragment(s) in changes/: echo "changed something" > changes/<PR#>.<changetype>.rst (see below for change types).
  • Start a romancal regression test (https://github.com/spacetelescope/RegressionTests/actions/workflows/romancal.yml) with this branch installed ("git+https://github.com/<fork>/rad@<branch>").
  • Update relevant roman_datamodels utilities and tests.

News fragment change types:

• changes/<PR#>.feature.rst: new feature
• changes/<PR#>.bugfix.rst: fixes an issue
• changes/<PR#>.doc.rst: documentation change

wow I didn't know you could define global vars!

Is this helpful without being able to easily tag an associated roman_datamodel? Typically we link the RCAL tests to the RDM PRs for that reason.

I'd say this is still helpful.

At the moment the 3 packages are quite entangled and as you mentioned almost every rad change requires a roman_datamodels PR (since the rad change breaks roman_datamodels). However most of these breakages are due to the maker utilities being out of sync with rad. Most romancal steps don't use maker utilities (and likely none should) and may use the new rad changes without issue.

This will also help to catch failures that wouldn't be seen in the roman_datamodels tests.

Okay - it doesn't hurt as long as it isn't a blocking test.
