Unable to retrieve a required scan factory from IoC

[derevnjuk]

The default scan factory is not registered using a ScanFactory interface as an injection token into the IoC container.

  [Fact]
  public void AddSecTesterScan_ReturnsScanFactory()
  {
    // arrange
    _services.AddSingleton(_config);
    _services.AddSecTesterBus();

    // act
    _services.AddSecTesterScan();

    // assert
    using var provider = _services.BuildServiceProvider();
    var result = provider.GetRequiredService<ScanFactory>();
    result.Should().BeOfType<ScanFactory>();
  }
