• Use Microsoft.Extensions.DependencyInjection for Dependency Injection
• Use In Memomry Database for DB Operation
• Use Microsoft.Extensions.Logging for logging
• Use Serilog nuget package to write logs in file

Web API consists of three operation:

1. Saving the Product List with unique Id and time stamp.

   http://localhost:61247/api/product/PutProducts

    [{
        "id":"2da1a1ad-4d88-4794-b162-e22e5d2cc8dd",
        "timestamp": "2018-07-18T10:29:33.0842849Z",
        "products":[{"name":"Product 1","quantity":5,"sale_Amount":100.0},
              {"name":"Product 2","quantity":50,"sale_Amount":500.0},
              {"name":"Product 3","quantity":30,"sale_Amount":300.0},
              {"name":"Product 4","quantity":500,"sale_Amount":200.0},
              {"name":"Product 5","quantity":100,"sale_Amount":1000.0}]
      },
      {
        "id":"13d06b5c-81b8-4132-bab3-e96a47a14bc0",
        "timestamp": "2018-07-18T10:29:33.0842849Z",
        "products":[{"name":"Product 10","quantity":5,"sale_Amount":100.0},
              {"name":"Product 11","quantity":50,"sale_Amount":500.0}]
      }
      ]
   

2. Get the list of all the products with unique id and time stamp.

   http://localhost:61247/api/product/GetAllProducts

    [
      {
          "id": "2da1a1ad-4d88-4794-b162-e22e5d2cc8dd",
          "timestamp": "2018-07-18T10:29:33.0842849Z",
          "products": [
              {
                  "id": 1,
                  "name": "Product 1",
                  "quantity": 5,
                  "sale_Amount": 100
              },
              {
                  "id": 2,
                  "name": "Product 2",
                  "quantity": 50,
                  "sale_Amount": 500
              },
              {
                  "id": 3,
                  "name": "Product 3",
                  "quantity": 30,
                  "sale_Amount": 300
              },
              {
                  "id": 4,
                  "name": "Product 4",
                  "quantity": 500,
                  "sale_Amount": 200
              },
              {
                  "id": 5,
                  "name": "Product 5",
                  "quantity": 100,
                  "sale_Amount": 1000
              }
          ]
      },
      {
          "id": "13d06b5c-81b8-4132-bab3-e96a47a14bc0",
          "timestamp": "2018-07-18T10:29:33.0842849Z",
          "products": [
              {
                  "id": 6,
                  "name": "Product 10",
                  "quantity": 5,
                  "sale_Amount": 100
              },
              {
                  "id": 7,
                  "name": "Product 11",
                  "quantity": 50,
                  "sale_Amount": 500
              }
          ]
      }
   

   ]

3. Get the product by product id.

   http://localhost:61247/api/product/GetProduct/1

    {
          "id": "2da1a1ad-4d88-4794-b162-e22e5d2cc8dd",
          "timestamp": "2018-07-18T10:29:33.0842849Z",
          "products": [
              {
                  "id": 1,
                  "name": "Product 1",
                  "quantity": 5,
                  "sale_Amount": 100
              }
             ]
           }
   

1. Use xUnit and Moq framework for unit testing
2. Use In Memomry Database for unit testing
3. Unit testing covers:
   • Model object creation
   • Database operation using Product Service
   • Product Controller methods
