单元测试项目奥尔良文件未找到异常

Question

我正在尝试对我制作的一个相当简单的应用程序进行单元测试，但在运行测试时遇到了一个非常奇怪的错误。

我所做的只是：

• 创建了一个新的类库
• 添加了对Microsoft.Orleans.TestingHost 和Microsoft.Orleans.OrleansProviders 两个版本1.1.2 的引用
• 运行测试并获得file not found exception

测试文件如下所示：

[TestFixture]
public class HelloWorldTests : TestingSiloHost
{
    //public HelloWorldTests()
    //    : base(new TestingSiloOptions
    //           {
    //               SiloConfigFile = new FileInfo(@"C:\_Foo\Host\Tests\OrleansConfigurationForTesting.xml")
    //           },
    //          new TestingClientOptions
    //          {
    //              ClientConfigFile = new FileInfo(@"C:\_Foo\Host\Tests\ClientConfigurationForTesting.xml")
    //          })
    //{
    //}

    [Test]
    public async Task When()
    {
        var grain = GrainFactory.GetGrain<IHelloGrain>(0);
        var reply = await grain.SayHello("Hello");

        Assert.That(reply, Is.EqualTo("Hello World"));
    }
}

^^ 从上面我什至尝试硬编码配置文件的位置。

堆栈跟踪（有趣的是它在我的 appdata 文件夹中寻找配置文件：

OneTimeSetUp: System.Exception : Exception during test initialization: 
Exc level 0: System.Runtime.Serialization.SerializationException: Type is not resolved for member 'Orleans.Runtime.Silo+SiloType,OrleansRuntime, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

   at Orleans.TestingHost.TestingSiloHost.<InitializeAsync>d__16.MoveNext()

Exception doesn't have a stacktrace

Answer 1

精神分裂，

如果您使用的是 MSTest 框架，只需为它所抱怨的每个项目添加 [DeploymentItem("missing_file_or_dll_name")]。如果您使用的是 xunit，则应将引用的 DLL 复制到输出目录，并且所有额外文件（如配置文件）应设置为“Copy To Output”。

如果您还需要什么，请告诉我。

Answer 2

有点旧，但值得来这里......

这是 NUnit 和/或其 VS 适配器的一个怪癖。

Orleans 扫描当前目录中的文件，但 NUnit 将其设置在其他地方，没有预期的文件存在。

因此，您必须在 Orleans 启动之前自己设置当前目录。

在你的测试命名空间中加入这样的东西：

[SetUpFixture]
public class PreFixture
{
    [OneTimeSetUp]
    public void SetUp() {
        Directory.SetCurrentDirectory(TestContext.CurrentContext.TestDirectory);
    }

}
