單元測試項目orleans文件未找到異常

Question

我正在嘗試對我制作的一個相當簡單的應用程序進行單元測試，但是在運行測試時遇到一個非常奇怪的錯誤。

我所做的就是：

• 創建一個新的類庫
• 添加了對Microsoft.Orleans.TestingHost和Microsoft.Orleans.OrleansProviders版本1.1.2引用
• 運行測試並獲得file not found exception

測試文件如下所示：

[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"));
    }
}

^^從以上我什至嘗試對配置文件的位置進行硬編碼。

堆棧跟蹤（有趣的是，它在我的appdata文件夾中尋找配置文件：

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 System.AppDomain.CreateInstanceFromAndUnwrap(String assemblyFile, String typeName, Boolean ignoreCase, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes)

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

Exception doesn't have a stacktrace

Answer 1

schizo，

如果您使用的是MSTest框架，則只需為它抱怨的每個項目添加[DeploymentItem("missing_file_or_dll_name")] 。 如果使用xunit，則應將引用的DLL復制到輸出目錄，並將所有其他文件（如配置文件）設置為“ Copy To Output ”。

需要幫助請叫我。

Answer 2

有點老了，但是值得在這里...

這是NUnit和/或其VS適配器的怪癖。

Orleans會掃描當前目錄中的文件，但是NUnit會在其他位置設置此文件，而這些文件都不在其中。

因此，您必須在Orleans啟動之前自行設置當前目錄。

在測試的名稱空間中放入以下內容：

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

}
