MSSQL 2019 is used through Docker. In order to generate your database please change the ConnectionString at appsettings.json and run dotnet ef database update under Infrastructuer layer.
Once the application is opened it will seed some date like Cart, Item and ItemDiscountRule. Their ids will be
Cart1 - 4e5fc42c-4a3a-46bf-bdc6-93e67e1e9abb
Cart2 - 9370d3af-7c05-46a8-940e-250f21cbbb76
Cart3 - ee1605d8-9bcd-4054-811e-27d5985bee64
Item1 (Vase) - e5715f5d-5c72-4564-9bbd-31bdedb93bed
Item1 (Big mug) - af3987bb-8a3b-4e53-b61b-858883655c8e
Item1 (Napkins pack) - 40ebcec1-9268-4e34-8d10-a47bd9d10fa4
ItemDiscountRule1 = e0b358c4-b225-42b0-a272-1846b94ee4db - the rule for Big mugs (2 for 1.5)
ItemDiscountRule1 = c0a7d3c6-c259-4987-b9dd-f480a7f1a342 - the rule for Napkins pack (3 for 0.9)
Please not that there is no CartItems seeded. it will require to add some manually through API (Swagger available).
