Can I use mstest.exe without installing Visual Studio?

问题

I want to use mstest.exe to run my unit test on build server, but I don't want to install Visual Studio on the build server. Can I just install MSTest without Visual Studio?

回答1:

It is possible to run mstest.exe without visual studio.
Download one of the Agents for Visual Studio ISO's below and install the Test Agent on the server:

Visual Studio 2017 (127MB disk space, less than that for download)
Visual Studio 2015 (128MB setup, 2GB disk space required)
Visual Studio 2012 (224MB)
Visual Studio 2013 (287MB)
Visual Studio 2010 (515MB)

This installs everything needed for running mstest.exe from the command line and is much lighter weight than visual studio. ~500mb download and around ~300mb to install just the test agent if I remember correctly.

UPDATE

For versions older than VS 2017, look here:

This answer pertains specifically to Visual Studio 2017, and the answer is yes. Please be aware, however, that Microsoft (still) doesn't provide any sort of official API for locating the relevant executables (MSBuild.exe and MSTest.exe), so you are stuck reading registry keys and/or probing various directories to locate these files. You've been warned.

If you only need to build your unit test project(s), install the package MSTest.TestFramework into those project(s) and remove the reference to Microsoft.VisualStudio.QualityTools.UnitTestFramework from them. Now all you need is to install the Visual Studio 2017 Build Tools and invoke msbuild.exe to perform the build.
If you need to run your tests as well, things become trickier:
- The simplest solution is to install VS2017 Community Edition (which includes both msbuild and mstest) - but I am unsure of the legality of this, and am not a lawyer, so be careful!
- A legally safer solution (and far lighter, in terms of disk space) is to install the Visual Studio 2017 Test Agent and then Build Tools for Visual Studio 2017 (exact order is vital¹); this will give you MSTest.exe and vstest.console.exe which you can then call out to. Do note that actually figuring out where these executables reside is a pain, because they won't exist in the same directory structure as MSBuild.exe in Build Tools.

Finally, and very importantly: if you do use MSTest.TestFramework and still need to be able to discover and run tests from within the Visual Studio IDE, you'll also need MSTest.TestAdapter installed in your unit test project(s).

^{1: While VS2017 supports side-by-side installs, it uses a single registry key that only records the most recent install. Hence, if you install Test Agent last, the key will point to its install directory... but Test Agent doesn't include MSBuild.exe, so any code that relies on this registry key to figure out that executable's path, will fail. Why Microsoft couldn't have made the Test Agent an optional part of Build Tools (so that all the EXEs live in the same directory hierarchy) is anyone's guess.}

I think you probably can, but its definitely not supported.

I've found this blog article written by someone who claims to have MSTest working without Visual Studio installed.

@crocpulsar, you need to install Visual Studio on your build server, but you do NOT need to buy an additional licence.

There are just way too many dependancies to getting build & MSTest to work without VS installed, and it is most definately not supported.

As long as the person who starts the build has a licence, you do not need one for the build server. This has been the case since the dark days of 2005, and as long as there is edition parity then you are OK.

If everyone in your team has Ultimate, then you are free to install it on the build server; but if one of your team member's has Premium, then you should ideally install Premium on the build server. This also enables lots of other bits like Code Coverage, Test Impact Analysis, and Architecture Validation among others.

I just got this working on my servers without installing the Visual Studio 2017 IDE. My requirement was

Build projects
Build test projects
Run tests using VSTest (I believe it is a similar process for MSTest)

I had to do a combination of a few things stated in other answers and then also another one here.

VS2017:

BuildTools - This can be found on the Microsoft downloads page, and then scroll down to "Tools for Visual Studio 2017" -> "Build Tools for Visual Studio 2017"
TestAgent - This can be found on the Microsoft downloads page, and then scroll down to "Tools for Visual Studio 2017" -> "Agents for Visual Studio 2017"
Nuget Package to include the visual studio unit testing dll - This can be found here

Step 3 was to fix the following issue:

"Could not resolve this reference. Could not locate the assembly "Microsoft.VisualStudio.QualityTools.UnitTestFramework""

Which then caused:

"error CS0234: The type or namespace name 'VisualStudio' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?) "

I did not have to add any references to the project. However, the path to the vstest.console.exe is contained in the TestAgent folder (for me it was "C:\Program Files (x86)\Microsoft Visual Studio\2017\TestAgent\Common7\IDE\CommonExtensions\Microsoft\TestWindow")

Here are the steps I took to get my build server to run MsTest without installing VS 2012:

Created 'Mstest' directory folder in c:\dev.
Copied 'Mstest.exe' and 'Mstest.exe.config' from C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE to 'Mstest' directory
Copy Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll to 'Mstest' directory
Created 'assemblies' directory in 'Mstest' folder
Extracted all v11 Microsoft.VisualStudio.QualityTools.*.dlls from C:\Windows\assembly to 'Mstest/assemblies' directory
Copy all 'v11' Microsoft.VisualStudio.QualityTools..dlls and Microsoft.VisualStudio.TestTools..dlls from C:\Windows\Microsoft.NET\assembly\GAC_MSIL to 'Mstest/assemblies'
Copy all v11 Microsoft.VisualStudio.QualityTools..dlls and Microsoft.VisualStudio.TestTools..dll from C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\PrivateAssemblies to 'Mstest/assemblies'
Add 'assemblies' to the 'privatePath' attribute of in 'Mstest.exe.config'
Export 'HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Microsoft/VisualStudio/11.0/Enterprise/QualityTools and apply it to hudson box.
Copy QTAgent32.exe and QTAgent32.exe.config to 'MsTest' directory from C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE
Add 'assemblies' to the 'privatePath' attribute of in 'QTAgent32.exe.config'
Copy 'msdia110.dll' from 'C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Packages\Debugger' to 'MsTest/assemblies'
Register 'msdia110.dll' with c:/windows/syswow64/regsvr32.exe /i '../mstest/assemblies/msdia110.dll'(This threw an error, but for some reason it still worked. I ran it a couple times and tried different regsvr32.exe versions before I checked, but it's there in the registry)
Add environment variable 'MSTEST_HOME' and set it to 'c:\dev\mstest\' or to your path. I used the environment variable in my build script.

Debugging MsTest execution error:

Add to 'MsTest.exe.config'

<system.diagnostics> 
  <trace autoflush="true" indentsize="4"> 
    <listeners> 
      <add name="EqtListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="C:\MsTest.log" /> 
    </listeners> 
  </trace> 
  <switches> 
    <add name="EqtTraceLevel" value="Verbose" /> 
  </switches> 
</system.diagnostics>

MSTest was announced for .NET Core users. The announcement has usage example with the dotnet tool. I haven't figured myself how to get the standalone mstest executable.

回答8:

If you need to run mstest.exe webtest tool then you can install Visual Studio Enterprise trial and make sure to run it at least once (just start it) under account under which test will be running with nothing additional needs to be done. So if your test run under System account then you need to use something like below

PS C:\agent> psexec -s cmd.exe
C:\Windows\system32>"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\mstest.exe"
Microsoft (R) Test Execution Command Line Tool Version 15.0.27520.0
Copyright (c) Microsoft Corporation. All rights reserved.

Please specify tests to run, or specify the /publish switch to publish results.
For switch syntax, type "MSTest /help"
