Which test runner works with VSTS and ASP.NET Core?
<p>I'm writing an ASP.NET Core web app and my aim is continuous integration and continuous delivery to Azure using Visual Studio Team Services (VSTS).  I've got to the point where the HelloWorld basic app builds and deploys and is up and running.</p>

<p>I am now at the stage where I want to add unit tests and have those executed as part of the build.</p>

<p>I don't need cross platform, and I have prior experience with MSTest so that was my first port of call.  However some initial investigation indicates that it isn't as straightforward as adding an MSTest project and away you go.  Particularly with the VSTS build.</p>

<p>So the question is what is the least painful way of getting a test framework in place and CD into Azure...</p>

<ul>
<li>MSTest</li>
<li>xUnit</li>
<li>Other?</li>
</ul>

<p>Just to reiterate...I want to get tests running against my ASP.NET Core web app on a VSTS build server as part of my CI.  Has anyone successfully done this with one of the above frameworks without too many headaches?</p>
