运行某些特定测试时，vstest崩溃 [英] vstest crashed when running some particular tests

问题描述

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

When I let run all tests (ca. 800 tests) in my solution, after some time a popup window with error is shown that vstest.executionengine.x86.exe has stopped working.

我得到的一些问题详细信息的示例在这里:

在VS输出窗口中，我得到:

In VS output window I get:

------ 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，所以我无法做到这一点.

When I tried to enable local crash dumps I found out that there is no such registry key so I haven't been able to do it.

我找到了所有测试(22个测试)，导致vstest .-.exe崩溃，对它们进行了注释，然后再次运行所有测试，而没有那些错误的"测试.一切正常.

I Located all test (22 tests) causing crash of vstest.---.exe, commented them and run all test again and without those "wrong" tests. Everything runs fine.

这些测试可能有什么问题?它们都是过去使用过的旧测试.如何找到问题?

What can be wrong with those tests? They all are old tests which was working in past. How to locate a problem?

推荐答案

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种测试中的一种，以查明是否存在递归问题.

In my experience, StackoverFlowExeptions are very often caused by some recursive method call that never terminates. Try debugging one of those 22 test to find out if recursion is the issue.
