Question

我有一个围绕OpenCover的包装脚本，该脚本与NUnit一起运行。脚本如下：

测试dll。
一个NUnit过滤器。
用于限制覆盖范围的程序集列表（转换为OpenCover过滤器）。

我试图了解限制范围的工作原理，因此我使用相同的测试dll和NUnit过滤器运行了两次脚本，但程序集列表不同。

运行＃1-限制从给定解决方案文件中获取的多个程序集

要点：

NUnit运行了4秒钟

运行＃2-由一个程序集限制

No results, this could be for a number of reasons. The most common reasons are:
    1) missing PDBs for the assemblies that match the filter please review the
    output file and refer to the Usage guide (Usage.rtf) about filters.
    2) the profiler may not be registered correctly, please refer to the Usage
    guide and the -register switch.

C:\Xyz\tip>

要点：

使用过滤器"+[DataSvc]*"
NUnit运行了63秒
没有报道

检查结果

C:\Xyz\tip> cat ~\AppData\Local\Temp\a24272_20190611185746\HcmAnywhereUnitTests.CoverageResult.xml | sls "ModulePath.+DataSvc"

      <ModulePath>C:\Xyz\tip\UI\HcmAnywhereUnitTests\bin\Debug\DataSvc.dll</ModulePath>


C:\Xyz\tip> cat ~\AppData\Local\Temp\a24272_20190611185855\HcmAnywhereUnitTests.CoverageResult.xml  | sls "ModulePath.+DataSvc"
C:\Xyz\tip>

有一个间接证据表明DataSvc在第二次运行中已配置文件-NUnit完成完全相同的测试需要63秒，而之前需要4秒。实际上，DataSvc远远大于首次运行中提供的解决方案中的所有程序集。所以，这对我来说很有意义。

但是为什么没有覆盖？怎么了？

如何正确限制OpenCover报告的覆盖代码？
