未找到测试服务器 returns 404

Question

我正在为我的 Web api 项目使用 aspnetcore 3.0 预览版 7。目前我正在实施集成测试。（首先为了使测试更容易，我注释掉了控制器上的 Authorize 属性。）

服务器响应“404 未找到”。我对启动中不再有 "usemvc" 感到困惑 - 我现在应该在设置测试服务器时做些不同的事情吗？或者有人知道导致 404 的原因吗？（用于 3.0 集成测试的 MS 文档尚未更新）。我也试过预览 8，但同样的问题。

测试class：

   [OneTimeTearDown]
    public virtual void Cleanup()
    {
        _unAuthenticatedServer.Dispose();
    }

    [OneTimeSetUp]
    public virtual void Initialize()
    {
        _unAuthenticatedServer = CreateServer(null);
    }

    protected TestServer CreateServer(
        string currentDirectory = null)
    {
        IWebHostBuilder webHostBuilder = WebHost.CreateDefaultBuilder();

        webHostBuilder.UseContentRoot(currentDirectory == null
            ? Directory.GetCurrentDirectory()
            : Directory.GetCurrentDirectory() + $"\{currentDirectory}");


        webHostBuilder.UseStartup<TestStartup>();
        webHostBuilder.UseEnvironment("Test");

        webHostBuilder.ConfigureAppConfiguration((_, config) => config.AddJsonFile("appsettings.Test.json"));

        return new TestServer(webHostBuilder);
    }

    [Test, Order(1)]
    public async Task Should_Get_Games_Return_StatusCode_Ok()
    {
        //Arrange
        IList<GameDto> expectedDtos = GameDtoTestData.Games;

        //Act
        HttpResponseMessage responseMessage = await _unAuthenticatedServer
            .CreateClient()
            .GetAsync("api/games");

        //Assert
        responseMessage.StatusCode.Should().Be(HttpStatusCode.OK); // but is: 404 NotFound

        var responseString = await responseMessage.Content.ReadAsStringAsync();
        IEnumerable<GameDto> result = JsonConvert.DeserializeObject<IEnumerable<GameDto>>(responseString);

        result.Should().BeEquivalentTo(expectedDtos);
    }

控制器：

[Route("api/[controller]")]
[ApiController]
public class GamesController : ControllerBase
{
    private readonly IGameService _gameService;

    public GamesController(IGameService gameService)
    {
        _gameService = gameService;
    }

    [HttpGet]
    public async Task<ActionResult<IEnumerable<GameDto>>> Get()
    {
        return Ok(await _gameService.GetAsync());
    }
}

对我有用的是将包含 Startup class 的程序集注册为 Mvc 应用程序部分。

在您的启动 class 中，将以下代码添加到 IServiceProvider ConfigureServices(IServiceCollection services):

services
  .AddMvc(...)
  .AddApplicationPart(typeof(Startup).Assembly)

您需要将包含 Startup class 的程序集注册为 Startup class 本身中的应用程序部分，这似乎有点奇怪；但这种方法对我有用。
