在TeamCity 4中使用NUnit-2.5 RequiresSTAAttribute

Question

使用TeamCity，我试图获得一个需要STA线程才能运行的(TestAutomationFX)测试。

它通过一个自定义的app.config来配置NUnit 2.4.x (8) (如Gishu所述，谢谢，在http://madcoderspeak.blogspot.com/2008/12/getting-nunit-to-go-all-sta.html中描述)

它通过以下方式工作：

/// <summary>

/// </summary>
public static class CrossThreadTestRunner // To be replaced with (RequiresSTA) from NUnit 2.5
{
    public static void RunInSTA(Action userDelegate)
    {
        Exception lastException = null;

        Thread thread = new Thread(delegate()
          {
              try
              {
                  userDelegate();
              }
              catch (Exception e)
              {
                  lastException = e;
              }
          });
        thread.SetApartmentState(ApartmentState.STA);

        thread.Start();
        thread.Join();

        if (lastException != null)
            ThrowExceptionPreservingStack(lastException);
    }

    [ReflectionPermission(SecurityAction.Demand)]
    static void ThrowExceptionPreservingStack(Exception exception)
    {
        FieldInfo remoteStackTraceString = typeof(Exception).GetField(
          "_remoteStackTraceString",
          BindingFlags.Instance | BindingFlags.NonPublic);
        remoteStackTraceString.SetValue(exception, exception.StackTrace + Environment.NewLine);
        throw exception;
    }
}

我希望能用一些内置的东西。所以NUnit 2.5.0.8322 (Beta1)的RequiresSTAAttribute似乎很理想。它可以独立工作，但不能通过TeamCity，即使我试图通过：

<NUnit Assemblies="Test\bin\$(Configuration)\Test.exe" NUnitVersion="NUnit-2.5.0" />

文档说runner支持2.5.0 alpha 4？(http://www.jetbrains.net/confluence/display/TCD4/NUnit+for+MSBuild)

可能是回答了我自己的问题，2.5.0Aplha4没有RequiresSTAAttribute，因此runner没有使用我的属性……

Answer 1

TeamCity 4.0.1包含NUnit 2.5.0 beta 2，我相信它应该适用于这种情况。

Answer 2

你能看看这是否有帮助吗？通过.config文件方法设置STA...与NUnit 2.5之前的版本相同

现在，我使用：

    private void ForceSTAIfNecessary(ThreadStart threadStart)
    {
        if (Thread.CurrentThread.GetApartmentState() == ApartmentState.STA)
            threadStart();
        else
            CrossThreadTestRunner.RunInSTA(threadStart);
    }

    [Test]
    public void TestRunApp()
    {
        ForceSTAIfNecessary(TestRunAppSTA);
    }

    public void TestRunAppSTA()
    {
        Assert.That(Thread.CurrentThread.GetApartmentState(), Is.EqualTo(ApartmentState.STA));
        ...
    }

而不是：

    [RequiresSTA]
    public void TestRunAppSTA()
    {
        Assert.That(Thread.CurrentThread.GetApartmentState(), Is.EqualTo(ApartmentState.STA));
        ...
    }
