我花了相当一段时间.NET6最初是为了建立我的单元测试套件而发布的.以下是我如何使用相同的Moq版本4.16.1来实现这一点:
单元测试从基类获得一个Moq HttpClientFactory:
public class UnitTests : BaseUnitTest
{
[Fact]
public async Task Should_Return_GetSomethingAsync()
{
// Arrange
IHttpClientFactory httpClientFactory = base.GetHttpClientFactory(new Uri("ExternalWebsiteUrlToMockTheResponse"), new StringContent("A Mock Response JSON Object"));
YourService yourService = new YourService(httpClientFactory);
// Act
Something something = yourService.GetSomethingAsync().Result;
// Assert
Assert.IsType<Something>(Something);
//..
}
在BaseUnitTest.cs类中:
using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Http;
using System.Text.Json;
using System.Threading;
using System.Threading.Tasks;
using Moq;
using Moq.Protected;
public class BaseUnitTest
{
public IHttpClientFactory GetHttpClientFactory(Uri uri, StringContent content, HttpStatusCode statusCode = HttpStatusCode.OK)
{
Mock<HttpMessageHandler> httpMsgHandler = new Mock<HttpMessageHandler>();
httpMsgHandler.Protected().Setup<Task<HttpResponseMessage>>("SendAsync", new object[2]
{
ItExpr.IsAny<HttpRequestMessage>(),
ItExpr.IsAny<CancellationToken>()
}).ReturnsAsync(new HttpResponseMessage
{
StatusCode = statusCode,
Content = content
});
HttpClient client = new HttpClient(httpMsgHandler.Object);
client.BaseAddress = uri;
Mock<IHttpClientFactory> clientFactory = new Mock<IHttpClientFactory>();
clientFactory.Setup((IHttpClientFactory cf) => cf.CreateClient(It.IsAny<string>())).Returns(client);
return clientFactory.Object;
}
您的服务类别或控制器:
public class YourService : IYourService
{
private readonly IHttpClientFactory _clientFactory;
private readonly HttpClient _client;
public YourService(IHttpClientFactory clientFactory)
{
_clientFactory = clientFactory;
_client = _clientFactory.CreateClient("YourAPI");
}
public async Task<Something> GetSomethingAsync()
{
using (var request = new HttpRequestMessage(HttpMethod.Post, _client.BaseAddress))
{
request.Content = new StringContent($@"{{""jsonrpc"":""2.0"",""method"":""Something"",""params"": [""{SomethingHash}""],""id"":1}}");
using (var response = await _client.SendAsync(request))
{
//System.Diagnostics.Debug.WriteLine(response?.Content.ReadAsStringAsync()?.Result);
if (response.IsSuccessStatusCode)
{
using (var responseStream = await response.Content.ReadAsStreamAsync())
{
var options = new JsonSerializerOptions { IncludeFields = true };
var something = await JsonSerializer.DeserializeAsync<Something>(responseStream, options);
// Check if the transactions from the address we're looking for...
if (something != null)
{
if (something.result?.from == address)
{
return something;
}
} } }
else {
string exceptionMsg = $"Message: {response.Content?.ReadAsStringAsync()?.Result}";
throw new YourGeneralException(response.StatusCode, exceptionMsg);
}
}
}
return null;
}
}
在你的节目里.反恐精英
builder.Services.AddHttpClient("YourAPI", c =>
{
c.BaseAddress = new Uri("ExternalWebsiteUrlToMockTheResponse");
c.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
c.DefaultRequestHeaders.UserAgent.TryParseAdd("Your Agent");
});
可以展开BaseUnitTest.ccs类也要进行链式测试
