FunctionalDev.Abstractions.Http 1.0.2

FunctionalDev.Abstractions

This library provides interfaces around the System.Net.Http library to enhance unit test capabilities. Simply add the following into dependency injection to load the abstractions, then use the abstracted versions in your code.

Setup

using FunctionalDev.Abstractions.Http;
...
services.AddHttpClientWrapper();

Using Abstractions

public class MyClassWithIHttpClientReference
{
	private readonly IHttpClient _httpClient;

	public MyClassWithIHttpClientReference(IHttpClient httpClient)
		=> _httpClient = httpClient;
...
	public async Task<bool> Result()
	{
		var response = await _httpClient.GetAsync("https://www.example.com");
		return response.IsSuccessStatusCode;
	}
}

public class MyClassWithIHttpClientFactoryWrapperReference
{
	private readonly IHttpClientFactoryWrapper _httpClientFactory;
	
	public MyClassWithIHttpClientFactoryWrapperReference(IHttpClientFactoryWrapper httpClientFactory)
		=> _httpClientFactory = httpClientFactory;
...
	public async Task<bool> Result()
	{
		var response = await _httpClientFactory.CreateClient().GetAsync("https://www.example.com");
		return response.IsSuccessStatusCode;
	}
}

Testing With Abstractions

[Fact]
public async Task MyClass_Result_ShouldReturnTrueIfHttpClientIsSuccessful()
{
	var httpClient = new Mock<IHttpClient>();
	httpClient.Setup(x => x.GetAsync("https://www.example.com"), new HttpResponseMessage
	{
		IsSuccessfulStatusCode = true
	});
	var result = new MyClass(httpClient.Object).Result();
	Assert.True(result);
}

[Fact]
public async Task MyClass_Result_ShouldReturnFalseIfHttpClientIsNotSuccessful()
{
	var httpClient = new Mock<IHttpClient>();
	httpClient.Setup(x => x.GetAsync("https://www.example.com"), new HttpResponseMessage
	{
		IsSuccessfulStatusCode = false
	});
	var result = new MyClass(httpClient.Object).Result();
	Assert.False(result);
}
