The objective of this service, as implied by its name, is to speed up the process of updating products' availability. This is achieved by parsing receipts and linking products to the corresponding shops in the database. We begin by addressing the more accessible digital receipts, before progressing to handling physical ones.

1. Install Python 3.11
2. Install Pipenv
3. Run export PIPENV_VENV_IN_PROJECT=1 && pipenv sync --dev
4. Run pipenv shell
5. Create database and required tables python src/migrations.py with EnvType.DEV
6. Run func start

1. Install Azure CLI
2. az login
3. az --version
4. func azure functionapp publish plante-receipt-parser

Run python -m unittest discover -s src/tests/unit

1. Set up environment variables locally:
   • TEST_COSMOS_DB_ACCOUNT_HOST=https://{Cosmos-DB-account-name}.documents.azure.com:443/
   • TEST_COSMOS_DB_ACCOUNT_KEY={key}
   • TEST_COSMOS_DB_DATABASE_ID=PlanteTest
2. Create database and required tables by running python src/migrations.py with EnvType.TEST
3. Run python -m unittest discover -s src/tests/integration

1. Set up environment variables locally:
   • TEST_COSMOS_DB_ACCOUNT_HOST=https://{Cosmos-DB-account-name}.documents.azure.com:443/
   • TEST_COSMOS_DB_ACCOUNT_KEY={key}
   • TEST_COSMOS_DB_DATABASE_ID=PlanteTest
   • APP_HOST=https://plante-receipt-parser-test.azurewebsites.net/api
2. Deploy service to test environment func azure functionapp publish plante-receipt-parser-test
   1. If the service was never deployed before, add these values to Function App Configuration:
      • TEST_COSMOS_DB_ACCOUNT_HOST=https://{Cosmos-DB-account-name}.documents.azure.com:443/
      • TEST_COSMOS_DB_ACCOUNT_KEY={key}
      • TEST_COSMOS_DB_DATABASE_ID=PlanteTest
      • ENV_NAME=test
3. Run python -m unittest discover -s src/tests/functional

The code aims at modularity and loose coupling. External interfaces like database and endpoint handlers should be easily replaceable. Schemas aim to add predictability and consistency to the domain objects but not at the expense of flexibility.
