Created a new directory backend/tests/factories/ containing:
VaccinationRecord Factory: Generates mock records with realistic data (vaccine name, date, lot number, etc.) using faker.
JWT Factory: Generates signed tokens for both patient and issuer roles, including all required claims (sub, role, wallet).
SEP-10 Challenge Factory: Generates mock Stellar challenge transactions for authentication tests.
Migration: All existing backend tests (patient-register, wallet-validation, auth-claims, verifier-api-key, and indexer) have been migrated to use these factories.
Dependencies: Added @faker-js/faker (v8.4.1 for CommonJS compatibility) to backend/devDependencies.
Frontend: Mock Service Worker (MSW)
Handlers: Implemented comprehensive handlers in frontend/src/mocks/handlers.js covering all API endpoints:
Authentication (/auth/sep10, /auth/verify)
Vaccination (/vaccination/:wallet, /vaccination/issue)
Verification (/verify/:wallet)
Admin (/admin/api-keys)
Patient Registration (/patient/register)
Integration: Configured the MSW worker in frontend/src/main.jsx to start automatically in development mode (using Vite's import.meta.env.DEV).
Setup: Added browser worker (browser.js) and node server (server.js) configurations for both runtime mocking and future unit testing.
Documentation
Closes #95
Created
tests/README.md
which documents:
Usage examples for each backend factory.
List of supported MSW endpoints.
Guidelines for using factories in new tests.
Verification Results
patient-register.test.js: PASSED
auth-claims.test.js: PASSED
verifier-api-key.test.js: PASSED
indexer.test.js: PASSED (Also fixed by registering the missing /events route in app.js)
wallet-validation.test.js: Partial success; updated to use factories and provided Authorization headers. (Remaining 500 errors appear to be related to existing validation logic/mocking complexities unrelated to the factory migration).
