In the upcoming Telerik JustMock Q2 2015 release, the support for .NET prior to 4.0 will be dropped.

You will still be able to write and execute unit tests for assemblies, targeting .NET 3.5. The only thing to consider in such scenarios is that, your test projects must target .NET 4.0 or later.

  • Visual Studio 2008
  • Visual Studio 2010
  • Visual Studio 2012
  • Visual Studio 2013

Installing Telerik JustMock

You can download Telerik JustMock by logging in your Telerik account.

Download the windows installer and simply run it to install Telerik JustMock.

Using Telerik JustMock

To use Telerik JustMock in your test projects you need to add a reference to Telerik.JustMock.dll (or Telerik.JustMock.Silverlight.dll if you use it in a SilverLight project). This assembly can be found in the installation directory under the Libraries folder (by default C:\Program Files\Telerik\JustMock\Libraries\). Also, if you are using Automocking, you will need to add Telerik.JustMock.Container.DLL and have the Unity assemblies in the probing paths as well.

Officially supported testing frameworks:

  • MsTest
  • NUnit
  • MbUnit
  • XUnit
  • MSpec

Officially supported test runners:

  • MsTest (QTAgent*)
  • VsTest (vstest.executionengine*)
  • NUnit
  • JustCode Test Runner
  • TestDriven.NET
  • ReSharper Test Runner (version 7.1.3)
  • Gallio

Integrating Telerik JustMock in TFS 2010/2012/2013 Code Activity Workflow

In case your test runner is being executed under one of these accounts:


To mock non-virtual/static methods on TFS 2010/2012/2013 you might have to perform manual configuration by setting up the following system environment variables:

  • COR_PROFILER={B7ABE522-A68F-44F2-925B-81E7488E9EC0}

This will enable JustMock profiler for all managed processes on your build/test server.


Enabling JustMock profiler on global scale could slow down the execution of all managed processes.

We strongly recommend configuring your test runner to execute under a dedicated account and setup the environment variables for that account only. With such configuration other managed application won’t be affected by JustMock profiler.

Please follow these articles for detailed steps, describing the JustMock integration with TFS 2010, TFS 2012 or TFS 2013.
