This is not a complete implementation. I wanted to focus on demonstrating SOLID principals and writing code that is easy to test.

The projects are as follows:

• RestaurantReviews.API
• • Main API entrypoint
• • Contains controllers for restaurant, review, and user
• • • controllers only contain endpoints that were requested or that I needed to test
• • Dependency Injection setup is in Startup.cs
• • Contains json data for testing
• RestaurantReviews.API.Tests
• • Contains unit tests for one controller and one model validator
• • Uses XUnit and Moq
• RestaurantReviews.Business
• • Contains managers for restaurant, review, and user
• • • Some input validation is done, but is definitely incomplete
• • • • Example: does not test to see if a user is submitting a duplicate review
• • Contains a Fluent model validator for reviews
• • • Checks for empty review content, invalid restaurantId, and invalid userId
• RestaurantReviews.Interfaces
• • Contains all of the interfaces
• RestaurantReviews.JsonData
• • Concrete implementations of the repository interfaces
• • Not unit tested because this is only meant to demonstrate that the rest of the code works
• RestaurantReviews.Models
• • Concrete implementations of the model interfaces
• • Models were kept as simple as possible

Notes:

• I did not implement anything as async
• I did not do much error handling

Enjoy!
