.net 如何在MacOSX上以64位运行nunit测试？

我有一个程序集需要在64位进程中运行，但无法在nunit runner中运行

我创建了一个测试代码，非常简单，只需在main函数和nunit测试函数中打印出指针大小：

using System;
using NUnit.Framework;

namespace PtrSize
{
    class MainClass
    {
        [Test]
        public static void Test()
        {
            Console.WriteLine ("IntPtr.Size                : {0}", IntPtr.Size);
            Console.WriteLine ("Environment.Is64BitProcess : {0}", Environment.Is64BitProcess);
        }

        public static void Main (string[] args)
        {
            Console.WriteLine ("IntPtr.Size                : {0}", IntPtr.Size);
            Console.WriteLine ("Environment.Is64BitProcess : {0}", Environment.Is64BitProcess);
        }
    }
}

然后我做了以下测试：

首先我确认mono是64位的

Build-Agent-Mac-01s-iMac:Debug BA-Mac-01$ ~/sandbox/mono64/bin/mono --version
Mono JIT compiler version 3.10.0 (tarball Thu Jan  8 09:23:28 CET 2015)

    TLS:           normal
    SIGSEGV:       altstack
    Notification:  kqueue
    Architecture:  amd64
    Disabled:      none
    Misc:          softdebug 
    LLVM:          supported, not enabled.
    GC:            sgen

然后我用这个mono运行我的测试程序，它是64位进程：

Build-Agent-Mac-01s-iMac:Debug BA-Mac-01$ ~/sandbox/mono64/bin/mono PtrSize.exe
IntPtr.Size                : 8
Environment.Is64BitProcess : True

然后我使用nunit test runner运行它，它始终处于32位模式，我也尝试了nunit-console-x86.exe，但仍然没有帮助

Build-Agent-Mac-01s-iMac:Debug BA-Mac-01$ ~/sandbox/mono64/bin/mono ~/Downloads/NUnit-2.6.4/bin/nunit-console.exe PtrSize.exe

有人对此有想法吗？

从Mono 4.2.1开始，安装程序包括64位版本的Mono。不幸的是，nunit控制台命令仍然以32位运行

要以64位方式运行nunit console，您仍然需要使用mono64命令：

mono64 /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/4.5/nunit-console.exe <path to dll>

mono64/Library/Frameworks/Mono.framework/Versions/Current/lib/Mono/4.5/nunit-console.exe
