TeubDev.Moq.AutoMock.HttpClient 0.0.1

Moq.AutoMock.HttpClient

A NuGet package for making HttpClients slightly easier to test.

This wraps and mocks the HttpMessageHandler class used by the HttpClient class and internally creates an HttpClient to be used by classes under test.

Usage

Setup

After creating an instance of the AutoMocker class (see Moq.AutoMocker), use the GetHttpClientMock extension method to create an instance of the HttpClientMock class.

var mocker = new AutoMocker();
var mockClient = mocker.GetHttpClientMock();

To set up to watch for a request, use the SetupRequest method, passing in a function that will determine if a particular request matches the setup or not.

var url = "https://google.com/";
mockClient
    .SetupRequest(m =>
        m.RequestUri == new Uri(url)
        && m.Method == HttpMethod.Get)
    .ReturnsAsync(new HttpResponseMessage
    {
        Content = new StringContent("This is the response"),
        StatusCode = System.Net.HttpStatusCode.OK,
    });

Note: If using relative URIs instead of absolute URIs (like in the example above), create base address and pass it into the optional parameter in GetHttpClientMock, and any request matching will need to account for both URIs.

var url = "stuff";
var baseAddress = new Uri("https://google.com/");
var mockClient = mocker.GetHttpClientMock(baseAddress);
// ...
    m.RequestUri == new Uri(baseAddress, url)

Verify

Similar to regular Moq mocks, verification is similar to setup.

mockClient.Verify(m =>
    m.RequestUri == new Uri(url)
    && m.Method == HttpMethod.Get, Times.Once);
