c# - 运行某些特定测试时 vstest 崩溃

Question

当我在我的解决方案中运行所有测试(大约 800 个测试)时，一段时间后会显示一个错误的弹出窗口，显示 vstest.executionengine.x86.exe 已停止工作。

一些问题细节的例子，我在这里得到:

在 VS 输出窗口中我得到:

------ Run test started ------
The active Test Run was aborted because the execution process exited unexpectedly. To investigate further, enable local crash dumps either at the machine level or for process vstest.executionengine.x86.exe. Go to more details: http://go.microsoft.com/fwlink/?linkid=232477
========== Run test finished: 0 run (0:03:55,0267906) ==========

当我尝试启用本地故障转储时，我发现没有这样的注册表项，所以我无法启用。

我找到了导致 vstest.----.exe 崩溃的所有测试(22 个测试)，对它们进行了评论并再次运行所有测试，没有那些“错误”的测试。一切运行良好。

这些测试有什么问题？它们都是过去有效的旧测试。如何定位问题？

Answer 1

根据我的经验，StackoverFlowExeptions 通常是由一些永不终止的递归方法调用引起的。尝试调试这 22 个测试中的一个，以确定递归是否是问题所在。
