How to Run

Prerequisites

1. Installed Java, sbt, Docker
2. docker-compose.yaml has been launched by Docker

---

Run Server

sbt run

• This will start the GraphQL server.
• Important: By default, all data from persistence and Kafka will be deleted during launch.
• To change this behavior, set the parameter:

app.clean-up-on-start = false

---

Run End-to-End Test Flow

sbt "testOnly e2e.BookingE2ETest"

• This will run a client that connects to the server and performs the following steps:
  1. Create a booking
  2. Call getHomeBookings and check the booking is present
  3. Try to create the same booking again → expect conflict response with alternative dates
  4. Call getHomeBookings and check the booking is still only one
  5. Check booking_conflicts table; conflict data should be present

---

Notes

• Original GraphQL schema has been changed:
  • Instead of _: String! # Format: YYYY-MM-DD, LocalDate is used in schema definition
  • The query bookings(homeId: ID!): [Booking!]! has been changed to bookings(homeId: UUID!): [Booking!]!
