我有一个UnitTests.dll,Common.dll被引用（都是用 VS2015 构建的）。

我有以下目录结构：

C:\Test\
    - UnitTests.dll
    - UnitTests.runsettings    
C:\Bin\
    - Common.dll

UnitTests.runsettings内容如下：

<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
    <RunConfiguration>
        <TargetPlatform>x64</TargetPlatform>
    </RunConfiguration>
    <MSTest>
        <MapInconclusiveToFailed>True</MapInconclusiveToFailed>
        <CaptureTraceOutput>False</CaptureTraceOutput>
        <DeleteDeploymentDirectoryAfterTestRunIsComplete>False</DeleteDeploymentDirectoryAfterTestRunIsComplete>
        <DeploymentEnabled>False</DeploymentEnabled>
        <AssemblyResolution>
            <Directory Path="C:\Bin\" includeSubDirectories="true" />
        </AssemblyResolution>
    </MSTest>    
</RunSettings>

我调用测试：

C:\Test> vstest.console.exe UnitTests.dll /settings:UnitTests.runsettings /inIsolation

vstest.console.exe指C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe。

我收到以下错误：

Starting test execution, please wait... 
Failed   TestMethod1 
Error Message:
    Test method UnitTests.UnitTest1.TestMethod1 threw exception: System.IO.FileNotFoundException: Could not load file or assembly 'Common, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

Stack Trace:

更多，启用 Fusion Log：

我是否面临某种缓存问题？如何说服vstest.console.exe寻找内部的依赖关系（理论上由元素C:\Bin\指出）？AssemblyResolution

更新：

在连接时作为错误提交给 MSFT （使用重现步骤 - 在底部的详细信息选项卡下）。

程序集分辨率的现有限制以及强制使用DeploymentItem属性根本无法扩展。冗余维护成本（开发人员被迫手动跟踪单元测试运行所需的依赖项）给测试带来了摩擦。由于这种摩擦而出现的任何问题都很难解决。

似乎Runsettings MSDN 文档在元素中有错字Directory，该属性path必须小写才能工作。如果您指定，您的运行设置文件应该可以工作

    <AssemblyResolution>
        <Directory path="C:\Bin\" includeSubDirectories="true" />
    </AssemblyResolution>

为所有必需的文件设置DeploymentItemAttribute ：

[DeploymentItem("Common.dll")]
[DeploymentItem("Common2.dll")]
[TestMethod]
public void TestFoo()
{
    Bar();
}
