如何告诉nunit-控制台在Mono下使用4.0？

Question

我在MonoDevelop下建立了一个简单的项目，可以在那里成功地运行测试(*)。

当我从命令行尝试nunit-trace.exe时，我得到以下信息：

 .../mono2/bin/Debug$ nunit-console mono2.exe
 NUnit version 2.5.10.0
 ...
 Runtime Environment - 
   OS Version: Unix 2.6.32.44
  CLR Version: 2.0.50727.1433 ( 2.10.8.1 (Debian 2.10.8.1-1~dhx1~lucid1) )

 ProcessModel: Default    DomainUsage: Single
 Execution Runtime: Default
 Unhandled Exception:
 System.ArgumentException: NUnit components for version 4.0.30319 of the CLR are not installed
 ...

如果我漏掉了什么重要的东西请告诉我。

nunit-gui给出了同样的错误。nunit-gui可以选择从2.0切换到4.0，但是当我尝试时，它又给了我同样的错误，所以不允许我更改它。

更多细节:Ubuntu10.04，使用http://badgerports.org/lucid.html存储库，所以Mono2.10.8.1。

根据MonoDevelop中的project，项目被设置为使用"Mono/.NET 4.0“。

更多信息：

/usr/bin/nunit-控制台包含以下内容：

#!/bin/sh

exec /usr/bin/cli /usr/lib/nunit/nunit-console.exe "$@"

并且/usr/lib/nunit/目录包含：

*：嗯，当我尝试使用更多外来的Nunit属性时，我遇到了一个问题；这就是我试图解决的真正问题，它使我找到了我上面描述的问题。然而，上面使用的exe只有两个简单的测试，它们在MonoDevelop中工作得很好。

诀窍是修改nunit-控制台(在Ubuntu10.04上使用badgerports，类似于/usr/bin/cli /usr/lib/nunit/nunit-console.exe)，告诉/usr/bin/cli使用.NET 4！

所以，当我执行这个命令时：

/usr/bin/cli --runtime=v4.0 /usr/lib/nunit/nunit-console.exe mytest.exe

我得到了这个输出：

NUnit version 2.5.10.0
...
Runtime Environment - 
   OS Version: Unix 2.6.32.44
  CLR Version: 4.0.30319.1 ( 2.10.8.1 (Debian 2.10.8.1-1~dhx1~lucid1) )

ProcessModel: Default    DomainUsage: Single
Execution Runtime: Default
..
Tests run: 2, Errors: 0, Failures: 0, Inconclusive: 0, Time: 0.040103 seconds
  Not run: 0, Invalid: 0, Ignored: 0, Skipped: 0

如果您只打算使用Net4，您可以编辑/usr/bin/nunit-控制台来始终设置它。

(真正的问题是/usr/bin/cli自动检测是选择net2而不是net4；但是经过大量搜索，我发现无法控制自动检测过程。)

撇开：我强调/usr/bin/cli的原因是，仅仅告诉nunit-控制台框架使用失败(参见下面)。也就是说，运行时版本必须提供给/usr/bin/cli，而不是nunit-控制台！

/usr/bin/cli /usr/lib/nunit/nunit-console.exe -framework=v4.0 mytest.exe
NUnit version 2.5.10.0
...
Runtime Environment - 
   OS Version: Unix 2.6.32.44
  CLR Version: 2.0.50727.1433 ( 2.10.8.1 (Debian 2.10.8.1-1~dhx1~lucid1) )

ProcessModel: Default    DomainUsage: Single
Execution Runtime: v4.0
Unhandled Exception:
System.ArgumentException: NUnit components for version 4.0 of the CLR are not installed
Parameter name: targetRuntime

Answer 2

使用nunit-控制台4而不是nunit-控制台。
