VS10调试器错误：测试主机进程意外退出 [英] VS10 debugger error: Test host process exited unexpectedly

问题描述

我在VS10中遇到了一些测试调试器的问题。所有测试都运行没有错误，但是当调试它中止时，我尝试读取对象数据。之后，此错误显示在摘要中：测试主机进程意外退出。

我无法看到有关错误的更多细节。如何访问/生成测试日志文件？或者甚至更好：有没有人遇到类似的问题？找到一个解决方案？

---

其他信息：

运行时测试数据在同一个libary程序集的对象上可用，只是一个类，我无法在运行时模式下访问。如果我使用断点：

• 影响对象的每一行： - 我可以看到运行时数据和测试通过


• 只有一个地方： - 测试将中止，没有数据可见


• 无断点： - 测试运行并通过

测试过去直到最近才能正常工作。在问题发生之前，当我将项目分成解决方案文件夹进行了一些解决方案更改。我没有做任何应该影响代码的更改。将项目移回原来的文件夹并不能解决问题，所以我想知道 - 这是Visual Studio本身的一个错误吗？

这是我试过的到目前为止：

• 重新构建和清理解决方案。


• 关闭Visual Studio并重新启动系统。


• 安装VS10 Service Pack 1


• 重新安装Visual Studio 10


• 在VS10 Ultimate和Premium上测试
• 
  
• 删除和重新生成解决方案文件


• 删除所有断点


• TraceAndTestImpact / Local.testsettings：Testing 超时>超时并将中止设置为30分钟。


• TraceAndTestImpact / Local.testsettings：单元测试>大会定义的文件夹


• TraceAndTestImpact / Local.testsettings：部署>启用部署目录和文件

我该如何解决？任何建议都是值得欢迎的。

解决方案

这里最有可能发生的一个事情是，当地人或汽车窗口在运行过程中引起副作用，导致故障。要验证这一点，您应该关闭自动属性评估

• 工具 - >选项


• 转到调试器菜单


• 取消选中启用属性评估和其他隐式函数调用

I have been having some problems with the test debugger in VS10. All tests are running without error, but when debugging it aborts when I try to read the object data. Afterwards, this error is displayed in the summary: Test host process exited unexpectedly.

I'm unable to see anymore details about the error. How do I access/generate test-log files? Or, even better: Has anyone experienced a similar problem? And found a solution?

Additional information:

The runtime-test-data is available on objects from same libary assembly, it's just one class I can't get access to in runtime mode. If I use breakpoints at:

• every line that affects the object: - I can see the runtime-data and the test passes
• only one place: - the test will abort and no data is visible
• no breakpoints: - the test runs and passes.

The test used to work fine until recently. Just before the problem occurred when I made some solution changes with dividing the projects into solution folders. I didn't make any changes that should affect the code. Moving the projects back to their original folder don't solve the problem, So I wonder - Is this a bug in Visual Studio itself?

Here is what I've tried so far:

• Rebuilding and cleaning the solution.
• Closing Visual Studio and rebooting my system.
• Installing VS10 Service Pack 1
• Reinstalling Visual Studio 10
• Testing on VS10 Ultimate and Premium
• Removing and regenerating solutions files
• Removing all break points
• TraceAndTestImpact/Local.testsettings: Testing Timeout > timeout and setting abort to 30 minutes.
• TraceAndTestImpact/Local.testsettings: Unit Test > Assembly folders defined
• TraceAndTestImpact/Local.testsettings: Deployment > Enable deployment directories and files

How can I fix this? Any suggestions are welcome.

解决方案

What's most likely happening here is that a property, local which is being evaluated in the locals or autos window is causing a side effect in the running process which leads to the failure. To verify this you should turn off automatic property evaluation

• Tools -> Options
• Go to the Debugger menu
• Uncheck "Enable Property evaluation and other implicit function calls"
