Documenting and testing web services

You can easily test a web service by making HTTP GET requests using a browser. To test other HTTP methods, we need a more advanced tool.

Testing GET requests using a browser

You will use Chrome to test the three implementations of a GET request – for all customers, for customers in a specified country, and for a single customer using their unique customer ID:

1. Start the Northwind.WebApi web service.
2. Start Chrome.
3. Navigate to https://localhost:5001/api/customers and note the JSON document returned, containing all 91 customers in the Northwind database (unsorted), as shown in Figure 16.3:
