Typemock have just released an official VSTS build extension to run Typemock Isolator based tests. Given there is now an official extension I have decided to deprecate mine, it is still available in the Marketplace but I would recommend using the official one
The new Typemock extension includes two tasks
The SmartRunner is a unit test runner, that can run nunit and mstest based tests. It handles the deployment of Typemock Isolator. SmartRunner can run on both Shared and On Premises Agents
Typemock with VSTests
This task acts as a wrapper to enable Typemock Isolator and then run your tests via VSTest. This task can only be used with On Premises Agents as the build agent needs to be running with admin privileges.
