Question

我正在尝试处理单元测试一个相当简单的应用程序，但我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版本1.1.2
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"));
    }
}

^^从上面我甚至尝试对配置文件的位置进行硬编码。

Stack Trace（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:

Exception doesn't have a stacktrace

Answer 1

精神分裂，

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

如果您还有其他需要，请告诉我。

Answer 2

有点旧，但值得在这里......

这是NUnit和/或其VS适配器的怪癖。

奥尔良会扫描当前目录中的文件，但NUnit会将其设置在其他位置，而这些文件都没有。

因此，您必须在奥尔良启动之前自己设置当前目录。

将这样的内容放在测试的命名空间中：

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

}

单元测试项目orleans文件未找到异常
