如何使VS忽略测试dll的代码覆盖率

可以在项目中添加运行设置文件。

在该文件中,您可以提到需要从代码覆盖范围中排除的DLL名称:

<ModulePaths>
  <Include>
    <!-- Include all loaded .dll assemblies (but not .exe assemblies): -->
    <ModulePath>.*\.dll$</ModulePath>
  </Include>
  <Exclude>
    <!-- But exclude some assemblies: -->
    <ModulePath>.*\\Fabrikam\.MyTests1\.dll$</ModulePath>
    <!-- Exclude all file paths that contain "Temp": -->
    <ModulePath>.*Temp.*</ModulePath>
  </Exclude>
</ModulePaths>

This page 和 This page 应该为您提供更多有关如何添加和如何配置单元测试的运行设置文件的详细信息。

希望这对你有帮助。

1.需要在测试项目中添加扩展名为.runsettings的Xml文件。添加此运行设置文件后,复制以下代码段并粘贴到运行设置文件中。

2.内部 模块路径 标签,有 排除 标签输入此标记可以提到需要从代码覆盖范围中排除的DLL名称或项目名称。

3.对于测试项目,我们应该提到项目名称,而不是它的DLL。例如:我的测试项目名是 Skyve.Helper.Document文件.测试 . 所以我在 排除 标签。

现在有了 ExcludeFromCodeCoverage 用于修饰排除的代码的属性。我一直用它很成功。

将此属性放在类或结构上会从代码覆盖率信息集合中排除该类或结构的所有成员。
