Epic sandbox access and adapter validation

[slusset]

Summary

Apply for Epic's FHIR sandbox at fhir.epic.com and validate the Epic FHIR and Flowsheet adapters against it.

Steps

1. Register an application at fhir.epic.com
2. Generate RSA key pair for backend JWT auth
3. Run EpicFHIRAdapter integration tests against sandbox
4. Run EpicFlowsheetAdapter (ADDFLOWSHEETVALUE) if sandbox supports it
5. Document any Epic-specific quirks discovered

Notes

• Approval takes days to weeks — start early
• Sandbox may have limited FHIR write support
• Epic's non-production environments may behave differently from prod

Acceptance criteria

• Successful OAuth2 backend JWT auth against Epic sandbox
• Observation.Create succeeds via EpicFHIRAdapter
• Integration tests added to tests/integration/test_epic_fhir_adapter.py

I think the issue here is that the tests/integration/test_epic_fhir_adapter.py file might be trying to use the EpicFHIRAdapter class, but it's not imported from anywhere in the codebase. I'd suggest checking if the Epic adapter is being added to the __all__ list in its corresponding file, or if it's being imported correctly in the test file. Can you confirm if the Epic adapter is being imported in the test file?

I checked the repo, and the specific import problem you described is not present in the current code.

EpicFHIRAdapter is already exported from the Epic adapter package via src/ehr_writeback/adapters/epic/__init__.py, where it is included in __all__.

Also, tests/integration/test_epic_fhir_adapter.py does not currently import EpicFHIRAdapter at all. Right now that test file only defines a FHIR_TEST_BASE_URL fixture and a placeholder async test with a TODO comment; there is no adapter instantiation yet.

So the immediate issue is not a missing import from __all__. The real gap is that the integration test has not been wired up yet to instantiate EpicFHIRAdapter with auth and exercise check_connection() or write_observation().

If useful, next step I can wire that test up against the Epic sandbox configuration.

Je pense qu'on devrait passer à l'étape suivante et vérifier si les intégrations tests sont bien configurées pour utiliser le EpicFHIRAdapter correctement. Pouvez-vous vérifier si le EpicFHIRAdapter est bien utilisé dans le fichier tests/integration/test_epic_fhir_adapter.py et si les paramètres de configuration pour l'adapter Epic sont corrects ?
