Question

I’m attempting to run unit tests from the command line. I tried using the mstest.exe program using the following command:

E:\VS Projects\...\>"C:\Program Files (x86)\Microsoft Visual Studio 11.0\
    Common7\IDE\MSTest.exe" /testcontainer:mytest.dll 
    /testsettings:"E:\VS Projects\...\Local.testsettings"

The mstest program responce was:

Microsoft (R) Test Execution Command Line Tool Version 11.0.50727.1
Copyright (c) Microsoft Corporation. All rights reserved.

Loading E:\VS Projects\...\Local.testsettings...
Loading mytest.dll...
mytest.dll
Unable to load the test container 'mytest.dll' or one of its 
dependencies. If you build your test project assembly as a 64 bit assembly, 
it cannot be loaded. When you build your test project assembly, select "Any 
CPU" for the platform. To run your tests in 64 bit mode on a 64 bit 
processor, you must change your test settings in the Hosts tab to run your 
tests in a 32 bit process. Error details: Could not load file or assembly 
'file:///E:\VS Projects\...\mytest.dll' or one of its dependencies. The 
module was expected to contain an assembly manifest.

Local.testsettings does include information, that the tests shall be run in 64-bit environment.

I can guess, that mstest expects an assembly instead of native test project and this is why it fails. If so, how can I run native tests from the command line? In the other case, how shall I configure the mstest to work properly?

Thanks for Hans Passant for guidance.

The solution is to use:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe
