Nancy.Bootstrapper.AppDomainAssemblyTypeScanner'抛出异常

当我在Nancy项目上执行单元测试时，我得到了一个异常。应用程序按预期运行，只有在运行单元测试时才出现问题。

我使用Nancy 0.23.2.0。我也使用Nancy. authentication . basic 0.23.2.0, Nancy. bootstrapers . unity 0.23.2.0和Nancy。在单元测试项目上测试0.23.2.0。

我得到了这个版本的南希src，可以跟踪问题到AppDomainAssemblyTypeScanner.UpdateTypes()，特别是linq表达式。

public static void UpdateTypes()
{
    UpdateAssemblies();
    types = (from assembly in assemblies
        from type in assembly.SafeGetExportedTypes()
        where !type.IsAbstract
        select type).ToArray();
}

我得到异常的测试代码是这样的:

[TestFixture]
public class IndexModuleTests
{
    private Browser _browser;
    [SetUp]
    public void SetUp()
    {
        var bootstrapper = new ConfigurableBootstrapper(bootstrapperConfigurator =>
        {
            bootstrapperConfigurator.RootPathProvider(new TestRootPathProvider());
            bootstrapperConfigurator.Module<IndexModule>();
            bootstrapperConfigurator.RequestStartup((container, pipelines, context) =>
            {
                context.CurrentUser = new UserIdentity {UserName = "demo"};
            });
        });
        _browser = new Browser(bootstrapper);          
    }
    [Test]
    public void ShouldAllowAuthenticatedUsersToBrowseSecuredPage()
    {
        var result = _browser.Get("/index", with => with.HttpRequest());
        result.StatusCode.Should().Be(HttpStatusCode.OK);
    }
}

我要测试的模块:

public class IndexModule : NancyModule
{
    public IndexModule()
    {
        this.RequiresAuthentication();
        Get["/"] = parameters => View["index"];
    }
}

应用程序引导程序看起来像这样:

public class Bootstrapper : UnityNancyBootstrapper
{
    protected override void ConfigureApplicationContainer(IUnityContainer contrainer)
    {
       contrainer.RegisterType<IUserValidator, UserValidator>();
    }
    protected override void ApplicationStartup(IUnityContainer container, IPipelines pipelines)
    {
        base.ApplicationStartup(container, pipelines);
        pipelines.EnableBasicAuthentication(new BasicAuthenticationConfiguration(
            container.Resolve<IUserValidator>(),
            "MyAppDomain"));
    }
    protected override void ConfigureConventions(NancyConventions nancyConventions)
    {
        nancyConventions
            .StaticContentsConventions
            .Add(StaticContentConventionBuilder.AddDirectory("js", @"js"));
        nancyConventions
            .StaticContentsConventions
            .Add(StaticContentConventionBuilder.AddDirectory("css", @"css"));
        nancyConventions
            .StaticContentsConventions
            .Add(StaticContentConventionBuilder.AddDirectory("img", @"img"));
        nancyConventions
            .StaticContentsConventions
            .Add(StaticContentConventionBuilder.AddDirectory("fonts", @"fonts"));
        base.ConfigureConventions(nancyConventions);
    }
}
