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。但如果我运行覆盖、分析或剖析,它会被计算在内,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。但是当我运行覆盖时,如果我使用 TEMP 目录,或者如果我输出 DLL(如上) NO FILE 包含在覆盖中(所以甚至不包括主程序集),生成的程序集就会丢失。

当我运行分析时,我只能看到调用(反射),但看不到生成的代码。当我进行分析时(我在注入的代码中有一些错误,例如未使用局部变量,并且对所有内容进行了 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(主要是覆盖率)使用覆盖率、分析和分析。

VS 2012 中的 Ok 代码覆盖率不完全支持动态生成的代码。

您可以运行我们的分析命令来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

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.

保存那个。该文件的特别之处在于 CodeCoverage\ModulePaths\Include 部分的 ModulePath 子项已被注释掉。这现在将包括它在代码覆盖率中找到的任何 dll。

现在单击测试 -> 测试设置 -> 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。您应该会看到您的 DynamicCode.dll 出现在您的覆盖结果中(我在下面隐藏了我的工作站名称):

请注意,我已在名为 .cs.txt 的文件中添加了一个新方法BONK,它(正确地)显示为 100% 未发现。
