If you need to instantiate IDeliveryItemResponse or IDeliveryItemListingResponse objects, or your custom strongly-typed models with custom data (that is when you don't want to connect to the Delivery service directly from your unit tests), you may want to inject your own instance of HttpClient.

First, you need to fake the HttpMessageHandler class. The method of doing so is well described at StackOverflow. We recommend using RichardSzalay.MockHttp NuGet package:

// Arrange
var mockHttp = new MockHttpMessageHandler();
mockHttp.When("https://deliver.kontent.ai/*").Respond("application/json", "<desired json>");

Then you create an instance of the HttpClient class:

var httpClient = mockHttp.ToHttpClient();

You can now use the fake HttpClient when creating an instance of the IDeliveryClient interface:

IDeliveryClient client = DeliveryClientBuilder
    .WithEnvironmentId(Guid.NewGuid())
    .WithDeliveryHttpClient(new DeliveryHttpClient(httpClient))
    .Build();

See the whole example in the SDK's HTTP client tests.
