.net - JetBrains dotCover 代码覆盖率分析失败，错误为 "Invalid stream header"

Question

我正在尝试使用 JetBrains dotCover 确定 Visual Studio 2015 中 .Net Core 解决方案的单元测试覆盖率。

不幸的是，它失败并出现错误“覆盖率分析:无效的流 header !”。

我使用的是 ReSharper Ultimate 版本 2016.3.2。

Answer 1

dotCover 2016.3 和新样式的“可移植”pdb 文件存在问题。

您可以:

• 通过编辑 project.json 中的属性来使用“完整”pdb 文件
• 取消选中 ReSharper → 选项 → dotCover → 常规中的“将未加载的解决方案程序集包含到覆盖率结果中”设置。

此问题将于 2017.1 修复
