Question

我正在尝试进行集成测试以在项目上工作，但相同的错误不断出现。用邮递员手动做同样的事情很好。

我尝试更改端口号并打开/关闭SSL，但是仍然出现相同的问题。

UserAPITest：

[TestClass]
    public class UserAPITest
    {
        private readonly HttpClient _client;
        private readonly IConfiguration _configuration;

        public UserAPITest()
        {
            _client = TestsHelper.Client;
            _configuration = TestsHelper.Configurations;
        }

        [TestInitialize]
        public void TestInitialize()
        {
        }

        [TestMethod]
        [DataRow(nameof(HttpMethod.Post), "api/User/refreshToken")]
        public async Task Initiation_Authorized_ShouldReturnNewToken(string httpMethod, string url)
        {
            _client.DefaultRequestHeaders.Authorization = TestsHelper.GetTestUserBearerHeader();
            var request = new HttpRequestMessage(new HttpMethod(httpMethod), url);

            var response = await _client.SendAsync(request);

            Assert.IsNotNull(response.Content); // value during debug added below

            Assert.AreEqual(HttpStatusCode.OK,response.StatusCode); // test fails here

// check for token inside response
            // Assert.IsTrue(Regex.IsMatch(response.RequestMessage.Content.ToString(), "^[A-Za-z0-9-_=]+\\.[A-Za-z0-9-_=]+\\.?[A-Za-z0-9-_.+/=]*$"));
        }
    }

TestsHelper：


        private static HttpClient SetClient()
        {
            HttpClient client;
            var host = new WebHostBuilder()
                                    .UseEnvironment("Development")
                                    .UseStartup<Startup>()
                                    ;

            var server = new TestServer(host);

            client = new HttpClient {BaseAddress = new Uri(Configurations["Tests:ApiClientUrl"], UriKind.RelativeOrAbsolute)};

            return client;
        }

        public static string GetTestUserToken()
        {
            var token = "someToken"; // there is an actual token here but I have removed it

            return token;
        }
        public static AuthenticationHeaderValue GetTestUserBearerHeader()
        {
            var token = GetTestUserToken();
            var bearerToken = new AuthenticationHeaderValue("Bearer", token);

            return bearerToken;
        }

预期结果：测试通过（返回令牌）或失败（返回未经授权的401）

实际结果：测试返回了301个来源已移动

响应值：

{StatusCode: 301, ReasonPhrase: 'Moved Permanently', Version: 1.1, Content: System.Net.Http.HttpConnection+HttpConnectionResponseContent, Headers:
{
  Cache-Control: no-cache
  Pragma: no-cache
  Proxy-Connection: close
  Connection: close
  Content-Type: text/html; charset=utf-8
  Content-Length: 668
}}

Answer 1

您需要将测试用例修改为

_client.DefaultRequestHeaders.Authorization = TestsHelper.GetTestUserBearerHeader();
var request = new HttpRequestMessage(new HttpMethod(httpMethod), url);

var response = await _client.SendAsync(request);
var content = await response.Content.ReadAsStringAsync();

Assert.IsNotNull(content);

Assert.AreEqual(HttpStatusCode.OK,response.StatusCode);

更新问题在TestServer和客户端上都存在

var server = new TestServer(Program.CreateWebHostBuilder(new string[] { }));
client = server.CreateClient();
client.BaseAddress = new Uri(Configurations["Tests:ApiClientUrl"]);

Answer 2

在构建测试http客户端时，请使用以下命令： <div class="btn-group float-right">  </div>代替server.CreateClient()

您正在执行的操作不起作用，因为您正在构建的测试服务器实际上并未公开http级别的终结点。您可以使用测试服务器和测试客户端来测试您的webapi / http集成，同时该测试会使内存中的整个http协议栈短路。
