我正在尝试使用.runsettings文件执行测试，但测试运行失败并显示以下消息：
------ Run test started ------
Some or all identity references could not be translated.
Operation is not valid due to the current state of the object.
========== Run test finished: 0 run (0:00:00,2280287) ==========
EventLog提供了有关错误的更多详细信息：

删除.runsettings文件可以解决问题，但我们要在coverage报告中包含一些要排除的程序集。
答案 0 :(得分：1)
事实证明，当您包含此类文件时，ASP.NET代码覆盖率集合将激活。这又需要重置应用程序池以将其自身附加到它。 （因此引用IIS7Resetter）。关闭ASP.NET代码Coverage收集功能可以解决错误：
<?xml version="1.0" encoding="utf-8"?>
<!-- File name extension must be .runsettings -->
<RunSettings>
<DataCollectionRunSettings>
<DataCollectors>
<DataCollector friendlyName="Code Coverage" uri="datacollector://Microsoft/CodeCoverage/2.0" assemblyQualifiedName="Microsoft.VisualStudio.Coverage.DynamicCoverageDataCollector, Microsoft.VisualStudio.TraceCollector, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<Configuration>
<CodeCoverage>
<!-- Include the below line in your .runsettings file-->
<CollectAspDotNet>False</CollectAspDotNet>
</CodeCoverage>
</Configuration>
</DataCollector>
</DataCollectors>
</DataCollectionRunSettings>
</RunSettings>
但这并没有解释出现了什么问题。由于Stack Trace提示App Pool用户，我们开始调查。事实证明，将应用池设置为LocalSystem或NetworkService实际上也可以解决问题。我们将其配置为.\SomeLocalUser。更多的修补工作找到了根本原因，用于获取应用程序池标识的代码不喜欢简短的符号。实际输入机器名称会完全修复它：MachineName\SomeLocaluser。我怀疑这是Visual Studio中的一个实际错误，它将在未来的时间框架内修复，但在此之前这两个选项可能会帮助其他人找出问题所在。
注意：默认情况下，默认情况下最好将CollectAspDotNet选项设置为False。只要您没有针对服务器运行集成测试或CodedUI测试，它就会大大加快您的测试运行速度。
