我创建了一个ASP.NET项目，并为它编写了一些集成测试。但是当我试图运行dotnet test时，出现了以下情况：

Starting test execution, please wait...
A total of 1 test files matched the specified pattern.
The active test run was aborted. Reason: Test host process crashed : Unknown command: --environment=Development

Test Run Aborted with error System.Exception: One or more errors occurred.
 ---> System.Exception: Unable to read beyond the end of the stream.
   at System.IO.BinaryReader.Read7BitEncodedInt()
   at System.IO.BinaryReader.ReadString()

   at Microsoft.VisualStudio.TestPlatform.CommunicationUtilities.TcpClientExtensions.MessageLoopAsync(TcpClient client, ICommunicationChannel channel, Action`1 errorHandler, CancellationToken cancellationToken)
   --- End of inner exception stack trace ---.

据我所知，有些东西试图用--environment=Development运行dotnet可执行文件，但此参数无效，即使它在Microsoft docs中使用。
我试着创建新的ASP.NET项目（没有控制器、服务、数据库等，只有API，什么都不做，测试也是空的），但我无法再次重现错误。
一开始，我无意中在同一个文件夹中创建了项目和解决方案，不得不手动将项目移到子文件夹中。这样做之后，一切都运行正常，所以我认为一切都很好。也许这就是原因。
下面是我在测试期间访问应用程序的方法：

// TestingApplication.cs
public class TestingApplication : WebApplicationFactory<Program>
{
    private readonly Guid _appId = Guid.NewGuid();

    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        // Add mock/test services to the builder here
        builder.ConfigureServices(services =>
        {
            services.AddMvcCore().AddApplicationPart(typeof(Program).Assembly);
            services.AddScoped(sp => new DbContextOptionsBuilder<EfDbContext>()
                .UseSqlServer(
                    $"DATABASE CONNECTION STRING")
                .UseApplicationServiceProvider(sp)
                .Options);
        });
    }

    protected override IHost CreateHost(IHostBuilder builder)
    {
        var host = base.CreateHost(builder);

        using (var serviceScope = host.Services.GetRequiredService<IServiceScopeFactory>().CreateScope())
        {
            var context = serviceScope.ServiceProvider.GetRequiredService<EfDbContext>();
            context.Database.EnsureCreated();
        }

        return host;
    }

    protected override void Dispose(bool disposing)
    {
        base.Dispose(disposing);
        
        using (var serviceScope = Server.Services.GetRequiredService<IServiceScopeFactory>().CreateScope())
        {
            var context = serviceScope.ServiceProvider.GetRequiredService<EfDbContext>();
            context.Database.EnsureDeleted();
        }
    }
}

// BaseTest.cs
public class BaseTest : IDisposable, IClassFixture<TestingApplication>
{
    protected readonly TestingApplication Application;
    private HttpClient? _client;

    protected HttpClient Client => _client ??= Application.CreateClient();
    
    public BaseTest(TestingApplication testingApplication)
    {
        Application = testingApplication;
    }

    public void Dispose()
    {
        Application.Dispose();
    }
}

更多信息：

• 单元测试工作正常
• 最初我忘记将<InternalsVisibleTo Include="NameOfTestsProject" />添加到主项目文件中，但无论哪种方法都不起作用。
• . NET 6，操作系统-Linux，集成开发环境-Jetbrains骑士
• 重建解决方案不起作用
• 为单元测试创建新项目也没有帮助

有人知道问题出在哪里吗？
"UPD"我想明白了
