动态生成代码的代码覆盖率,分析和分析

我有一个演示项目,它创建一个程序集并使用它。我也可以调试注入的代码。但是,如果我进行覆盖,分析或分析,它会被计算,但我想测量它。

代码:

CSharpCodeProvider codeProvider = new CSharpCodeProvider();
ICodeCompiler icc = codeProvider.CreateCompiler();
CompilerParameters parameters = new CompilerParameters();
parameters.GenerateExecutable = false;
parameters.GenerateInMemory = false; // debug enabled                
parameters.OutputAssembly = "DynamicCode.dll"; // if specified creates the DLL
parameters.IncludeDebugInformation = true;
CompilerResults results = icc.CompileAssemblyFromFile(parameters, "InjectedCode.cs.txt");

我创建DLL来检查生成的IL代码。我可以在VS中调试代码。但是当我运行coverage时,如果我使用TEMP目录,或者如果我输出DLL(如上所述),则生成的程序集就会被遗漏,因此覆盖范围中不包含任何FILE(因此甚至不包括主程序集)。

当我运行分析时,我只能看到调用(反射),但没有看到生成的代码。当我进行分析时(我在注入的代码中有一些错误,例如没有使用本地,以及所有内容的ofc分析),注入的代码没有报告任何问题。注入的代码:

namespace CodeInjection
{
    public static class DynConcatenateString
    {
        public static string Concatenate(string s1, string s2){
           //  System.Diagnostics.Debugger.Break(); // break here for debugger and also test comment output
            int a = 1+2+3+4+5; // complicated math
            int b = a+2;
            int c = 0;

            return s1 + " !"+b+"! " + s2;
        }
    }
}

我想对生成的代码(主要是覆盖范围)使用覆盖率,分析和分析。

答案 0 :(得分:1)

VS 2012中的Ok代码覆盖率不完全支持动态生成的代码。

您可以run our analyze command查看您的模块是否因为同样的原因而被跳过,或者是因为缺少符号/ p

答案 1 :(得分:0)

在您的项目中,添加一个新的xml文件并将其命名为dynamic.runsettings

它应包含以下内容:

    <?xml version="1.0" encoding="utf-8" ?>
<RunSettings>
  <DataCollectionRunSettings>
    <DataCollectors>
      <DataCollector friendlyName="Code Coverage" uri="datacollector://Microsoft/CodeCoverage/2.0" assemblyQualifiedName="Microsoft.VisualStudio.Coverage.DynamicCoverageDataCollector, Microsoft.VisualStudio.TraceCollector, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">

          <CodeCoverage>
            <ModulePaths>
<!--
About include/exclude lists:
Empty "Include" clauses imply all; empty "Exclude" clauses imply none.
Each element in the list is a regular expression (ECMAScript syntax).
An item must first match at least one entry in the include list to be included.
Included items must then not match any entries in the exclude list to remain included.
It is considered an error to exclude all items from instrumentation as no data would be collected.

保存。这个文件有什么特别之处是CodeCoverage \ ModulePaths \ Include部分注释掉了它的ModulePath子项。这将包括它在代码覆盖中找到的任何dll。

现在点击测试 - &gt;测试设置 - &gt;选择“测试设置文件”并指定dynamic.runsettings文件。您的代码覆盖率现在将使用此自定义设置文件。

单击“分析代码覆盖率”并运行您想要的任何测试。你应该看到你的DynamicCode.dll出现在你的报道结果中(我在下面隐藏了我的工作站名称):

请注意,我在名为BONK的.cs.txt文件中添加了一个新方法,并且(正确地)显示为100%未覆盖。
