Local test

Create a .env file in the tests folder with this content:

tenant_id=anonymous
localhost=http://localhost:4004

start the CAP Backend using:

npm run watch

This script does include the cds build step as otherwise the deployment to the HDI container fails as the MTX module returns no model found, skip build.

Create a new subscription using the PUT request in tests/01-subscribe.http. Test the endpoints with tests/beershop.http. You can also open http://localhost:4004/ via a browser and test the Fiori preview of the Beers entity.
