C# 使用WebApplicationFactory运行集成测试抛出CancellationTokenSource已在测试类清理时释放

我有一些Web Api控制器测试。这些是使用.NET核心测试提供的WebApplicationFactory构建的

• 当我一个接一个地运行这些控制器测试时，它们都通过了
• 当我一次运行这些控制器测试时（在VisualStudio中，右键单击测试项目并选择“运行测试”），所有测试都会失败，随机测试除外

打印屏幕1：全部成功

打印屏幕2：除一个外，所有操作均失败：

所有测试都包括一个[理论]传入MemberData以测试各种安全组合

7)  Project.UserRolesControllerTests.GetUserDetailsById_ReturnsConfiguredResult
  Duration: 1 ms

  Message: 
    [Test Class Cleanup Failure (Project.Controllers.UserRolesControllerTests)]: System.ObjectDisposedException : The CancellationTokenSource has been disposed.
  Stack Trace: 
    CancellationTokenSource.ThrowObjectDisposedException()
    RedisStorage.Dispose()

    AutofacServiceProvider.Dispose() line 121
    WebHost.Dispose()
    WebApplicationFactory`1.Dispose(Boolean disposing)
    WebApplicationFactory`1.Dispose()

我在Dotnet运行时项目上找到了一个。然而，我不确定这是同一个问题。而且，我似乎无法解决这个问题

有人有这方面的经验吗？我现在可以手动运行这些测试，但它也是DevOps上CI管道的一部分。我估计它也会在那里破裂

非常感谢

编辑：添加使用过的代码

public class MyCustomWebApplicationFactory<TStartup>
    : WebApplicationFactory<TStartup> where TStartup : class
{
    private UserConfiguration _userConfiguration;

    public void SetUser(UserConfiguration userConfiguration)
    {
        _userConfiguration = userConfiguration;
    }

    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        base.ConfigureWebHost(builder);

        Environment.SetEnvironmentVariable("Statistics:RedisDb", "<conn. string>");

        builder.ConfigureTestServices(services =>
        {
            services.AddMvc(options =>
            {
                options.Filters.Add(new AllowAnonymousFilter()); // Remove entire JWT-requirement for all controllers during test
            });
            services.AddScoped<IJwtService>(instance =>
            {
                var customJwtService = new CustomJwtService(() => _userConfiguration);

                return customJwtService;
            });
            services.AddScoped<IHttpRequestHeaderService>(instance =>
            new CustomHttpRequestHeaderService(() => _userConfiguration));
        });

        builder.UseEnvironment("Test");
    }
}

public class CommunityPostsControllerTests : IClassFixture<MyCustomWebApplicationFactory<CommunityPostsController>>

    public CommunityPostsControllerTests(MyCustomWebApplicationFactory<CommunityPostsController> factory)
    {
        _factory = factory;
    }

    public static IEnumerable<object[]> RoleAccess => new List<object[]>
    {
        new object[] { UserConfigurations.AdminCi1, Ci1EmployeePostInGroup, HttpStatusCode.OK},
        new object[] { UserConfigurations.EmployeeCi1, Ci1ParentPostInGroup, HttpStatusCode.Forbidden},
        // Omitted for readability
    };

    [Theory]

    public async Task GetPostById_ReturnsConfiguredResult(UserConfiguration userConfiguration, int communityPostId, HttpStatusCode expectedCode)
    {
        // Arrange
        _factory.SetUser(userConfiguration);
        var client = _factory.CreateClient();

        // Act
        var result = await client.GetAsync($"api/v1/communityposts/{communityPostId}", cancellationToken: CancellationToken.None);

        // Assert
        Assert.Equal(expectedCode, result.StatusCode);
    }

你的测试看起来怎么样？我已经用用法更新了帖子。你能更新到新版本的xUnit吗？也许这是一个已知的问题，并且已经解决了…@mu88遗憾的是没有。。。我在帖子中添加了软件包和版本。为什么要将

CommunityPostsController

传递到

MyCustomWebApplicationFactory

的泛型中？这应该是您的

启动

类，而不是控制器。我不确定这是否是问题所在，但您可能应该更新它。
