DotCover "cover“命令需要数小时才能生成快照

Question

我有一个WPF窗口应用程序的用户界面自动化。我们的管理层决定使用dotCover来计算覆盖率。在使用命令行进行简单的测试运行后，我正在尝试获得应用程序覆盖率。这就是它：

dotcover.exe cover coverage.xml

Coverage.xml文件内容如下：

<?xml version="1.0" encoding="utf-8"?>
<CoverageParams>
  <TargetExecutable>nunit3-console.exe</TargetExecutable>
  <TargetArguments>CI.UIAutomationTests.dll --where="test =~ /TC100/" --agents=1 --workers=1 --labels=All</TargetArguments>
  <TargetWorkingDir></TargetWorkingDir>
  <TempDir><!-- Directory for auxiliary files. Set to the system temp by default. --></TempDir>
  <Output>ClientCoverage_TC100.snapshot</Output>
  ...

测试已成功执行，耗时约为2+分钟。但随后它会停止大约2-3个小时，如果我让它工作，我会得到快照：

Test Run Summary
Overall result: Failed
Test Count: 1, Passed: 0, Failed: 1, Warnings: 0, Inconclusive: 0, Skipped: 0

所以问题是:为什么要花这么长时间？

我想它会分析你所有的第三方依赖关系。您是否尝试过对其进行筛选以仅分析具有您的命名空间的程序集？https://www.jetbrains.com/help/dotcover/Running_Coverage_Analysis_from_the_Command_LIne.html#filters_xml?section=

解决了。被测试的应用程序启动了另一个应用程序，并且它在测试结束后没有关闭。当我决定关闭它时，我意识到dot.cover不再卡住了。因此，解决方案是-关闭被测app的所有子进程
