Nopcommerce is the web application and for performance testing of the application Web performance test functionality of the VSTS can be used. Along with the accurate recording of the requests VSTS also provides well-formed UI for generating the load test on top of that.

If you don’t already have the web performance and load testing tools component installed, you’ll need to install it through the Visual Studio Installer. Open Visual Studio Installer from the Start menu of Windows. In Visual Studio Installer, choose the Individual components tab, and scroll down to the Debugging and testing section.

The source code will need to be shared with the TFVC repo. Click on Open in Visual Studio. Once Visual Studio.Net is opened go to the Team Explorer view and click on Manage Connections => Connect to Team Project Click on Servers to add the VSTS URL which will then show up for the projects created.

The VSTS Preview is a step in the right direction, but still lacks features that would allow it to be truly standalone. The inability to directly integrate existing Load Tests with VSTS’ CD is a serious omission.
