A roadmap in retrospective

IntelliTest in Visual Studio 2015 is the next generation of Pex.

The Fakes Framework in Visual Studio 2012 and 2013 and 2015 is the next generation of Moles & Stubs. Fakes is different from Moles, however, so moving from Moles to Fakes will require some modifications to your code. Moles will not be developed further, so we recommend to migrate to Fakes.

Code Digger for Visual Studio 2013 and 2013 is a lightweight version of Pex that allows you to explore public .NET methods in Portable Libraries directly from the code editor.

Thanks for your support, The Pex and Moles Team.

Pex and Moles

Pex and Moles are Visual Studio 2010 Power Tools that help Unit Testing .NET applications.

  • Pex automatically generates test suites with high code coverage. Right from the Visual Studio code editor, Pex finds interesting input-output values of your methods, which you can save as a small test suite with high code coverage. Microsoft Pex is a Visual Studio add-in for testing .NET Framework applications.

  • Moles allows to replace any .NET method with a delegate. The Fakes Framework in Visual Studio 2012 is the next generation of Moles & Stubs, and will eventually replace it. Moles supports unit testing by providing isolation by way of detours and stubs. The Moles framework is provided with Pex, or can be installed by itself as a Microsoft Visual Studio add-in.
