本文介绍了如何利用NAnt在.NET项目中进行NUnit自动化测试，包括编译测试代码、运行NUnit任务以及解决nunit2report任务中字符集不支持中文的问题。通过自定义C#代码和XSL文件，实现了UTF-8编码的测试报告生成。

最近做的项目是.NET的，准确来说，是一个ASP.NET的项目，项目要求采用NUnit测试，在每日的版本构建的时候，需要自动运行全体的测试任务。在Java中，用的最多的每日构建工具应该就是Ant了，当然，Maven也是个好东西。在.NET有个类似的工具，叫做NAnt，不过好像已经有1年左右没有更新了，不知道是不是这个NAnt没人维护了呢。

首先在SourceForge上下载了NAnt的安装包，还有，Nant-Contrib的也需要下载，否则很多扩展功能不能自动实现。把Nant解压缩，并且把Contrib的东西也一起解压缩在Nant的bin目录下。然后你再把Nant的bin目录添加到你的环境变量的Path下，这样就可以在命令行中运行nant命令了。

如果要进行NUnit测试，首先需要编译NUnit的测试代码。采用csc命令进行编译，如下所示

< csc target ="library"

output ="${nunit_dll}/Test.Isid.ResonaIB.Web.dll"

optimize ="true"

failonerror ="true"

rebuild ="true"

verbose ="${debug}" >

< sources >

< include name ="${src.path} /trunk/Test.Isid.ResonaIB.Web/Test.Isid.ResonaIB.Web/**/*.cs" />

</ sources >

< references >

< include name ="System.dll" />

< include name ="System.Data.dll" />

< include name ="System.Xml.dll" />

< include name ="${nunit_lib}/nunit.framework.dll" />

< include name ="${nunit_lib}/NMock2.dll" />

< include name ="${lib}/Isid.Copera.Web.FC.dll" />

< include name ="${build_dll}/Isid.ResonaIB.Web.FC.dll" />

< include name ="${build_dll}/Isid.ResonaIB.Web.PARAM.dll" />

< include name ="${build_dll}/Isid.ResonaIB.Web.BC.dll" />

< include name ="${build_dll}/Isid.ResonaIB.Web.Utils.dll" />

</ csc >

编译好了以后，记得吧编译的文件和你测试时候需要的dll文件放在同一个目录下，.NET程序运行的时候不像Java程序，Java程序只要你指定ClassPath就OK了，而.NET需要在同目录下寻找dll文件。然后就可以运行nunit任务了，代码如下所示。

< nunit2 verbose ="${debug}" >

< formatter type ="Xml" usefile ="true" extension =".xml" outputdir ="${target.path}/report" />

< test

assemblyname ="${nunit_dll}/Test.Isid.ResonaIB.Web.dll"

haltonfailure ="false"

appconfig ="${root}/nunit.config" />

</ nunit2 >

在这里要注意设置appconfig的属性，因为默认Nunit的版本是2.2的，如果你不是这个版本，需要自己Mapping上来，在这里我们来看一下nunit.config文件如何编写，如下所示

< configuration >

< runtime >

< assemblyBinding xmlns ="urn:schemas-microsoft-com:asm.v1" >

< dependentAssembly >

< assemblyIdentity name ="nunit.framework" publicKeyToken ="96d09a1eb7f44a77" culture ="Neutral" />

< bindingRedirect oldVersion ="2.4.1.0" newVersion ="2.2.8.0" />

</ dependentAssembly >

< dependentAssembly >

< assemblyIdentity name ="NMock2" publicKeyToken ="" culture ="Neutral" />

< bindingRedirect oldVersion ="1.0.2313.18049" newVersion ="1.0.2313.18049" />

</ dependentAssembly >

</ assemblyBinding >

</ runtime >

</ configuration >

在这里，就可以发现NUnit测试可以顺利运行了，生成一个xml的报告文件。我们当然希望看到一个更容易看懂的报告文件，这个时候，就需要用到nunit2report任务了。不过contrib所带的nunit2report任务稍微有一点缺陷，就是采用的字符集是ISO-8859-1，如果是欧洲人，美国人的话，自然没有问题，不过对于中国人来说，就会有问题了，因为如果程序出错，错误信息是汉语或者日语的话，是无法在ISO-8859-1这个字符集下显示的，经过转换后，生成的HTML中的中文或者日文都是问号了，那么如何去解决呢。在原来的contrib下基本上是没指望了，那么我们就自己模仿contrib的nunit2report任务来写一个UTF-8格式的。C#的代码如下所示。
