Frameworks and Libraries

• ASP.NET Core 2.2;
• Entity Framework Core (for data access);
• Entity Framework In-Memory Provider (for testing purposes);
• AutoMapper (for mapping resources and models);
• Swashbuckle (API documentation).

How to Test

First, install .NET Core 2.2. Then, open the terminal or command prompt at the API root path (/src/Supermarket.API/) and run the following commands, in sequence:

dotnet restore
dotnet run

Navigate to https://localhost:5001/api/categories to check if the API is working. If you see a HTTPS security error, just add an exception to see the results.

Navigate to https://localhost:5001/swagger to check the API documentation.

To test all endpoints, you'll need to use a software such as Postman.
