Microsoft Fakes is an isolation framework for creating delegate-based test stubs and shims in .NET Framework applications.
Microsoft Fakes is an isolation framework for creating delegate-based test stubs and shims in .NET Framework applications. The Fakes framework can be used to shim any .NET method, including non-virtual and static methods in sealed types.
The Fakes framework grew out of the Pex and Moles projects released by Microsoft Research. Microsoft notes that: "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."

(Aside: The Pex project evolved into the Intellitest feature in Visual Studio 2015.)
