How to run NUnit test in Visual Studio Team Services : <p>When I try to execute <strong>NUnit</strong> test in VSTS task I am getting the following error:</p>

<pre><code>Warning: The path 'C:\a\1\s\INCASOL.IP\packages' specified in the 'TestAdapterPath' does not contain any test adapters, provide a valid path and try again.
</code></pre>

<p>I have these tasks in VSTS:</p>

<p>The "Run unit test" task is configured as follows:

<p>Note I have set the "Path to Custom Test Adapters".</p>

<p>I think the dlls for NUnit are properly copied to packages folder because in "Nuget restore" task I can see the following:</p>

<pre><code>Added package 'NUnit.2.6.4' to folder 'C:\a\1\s\INCASOL.IP\packages'
</code></pre>

<p>Notes: The NUnit version is 2.6.4 and I'm using Hosted Agent</p>
