我有一个运行在Docker环境中的Postgres DB，它是在Xunit测试中使用FluentDocker设置的。
Xunit被配置为串行运行测试。
当运行单个测试时，一切都正常。
但是，当添加另一个测试（实际上只是复制第一个测试）并使用dotnet test在一个调用中运行两个测试时，第二个测试总是会失败。
我试着关闭数据库连接，在每次测试运行后停止容器等。但是错误仍然存在，并且它总是发生在同一行代码中。
这是测试的代码：

[Fact]
public async Task ShouldProjectUserRegistration()
{
  var file = Path.Combine(
    Directory.GetCurrentDirectory(),
    (TemplateString)"Resources/docker-compose.yml"
  );

  var service = new Builder()
    .UseContainer()
    .UseCompose()
    .FromFile(file)
    .RemoveOrphans()
    .ForceRecreate()
    .WaitForPort(
      "database",
      "5432/tcp",
      30000 /*30s*/
    )
    .Build();
  var container = service.Start();

  var PgTestConnectionString =
    "PORT = 5432; HOST = localhost; TIMEOUT = 15; POOLING = True; MINPOOLSIZE = 1; MAXPOOLSIZE = 100; COMMANDTIMEOUT = 20; DATABASE = 'marten'; PASSWORD = '123456'; USER ID = 'marten'";
  using var store = DocumentStore.For(
    options =>
    {
      options.Connection(PgTestConnectionString);
      options.AutoCreateSchemaObjects = AutoCreate.All;
      options.Projections.SelfAggregate<User>(ProjectionLifecycle.Inline);
    }
  );

  var id = Guid.NewGuid();
  var username = "jane.doe@acme.inc";
  var userRegistered = new UserRegistered(
    id,
    username
  );

  await using var session = store.OpenSession();
  session.Events.StartStream(
    id,
    userRegistered
  );

  await session.SaveChangesAsync();

  var user = session.Load<User>(id);
  await session.Connection?.CloseAsync();
  service.Stop();
  Assert.Equal(
    username,
    user?.Username
  );

这是docker-compose.yml：

version: "3"

services:
  database:
    image: library/postgres:14
    environment:
      POSTGRES_USER: 'marten'
      POSTGRES_PASSWORD: '123456'
      POSTGRES_DB: 'marten'
    ports:
      - "5432:5432"

例外情况：

我创建了一个可以找到on GitHub的repro。
