About MbUnit
The framework was first created by Jonathan 'Peli' de Halleux as a hobby project
while studying for his PhD. Later
Peli and Jamie Cansdale added support for MbUnit
to Jamie's NUnitAddin (later it would become the TestDriven.NET addin). After
Peli's departure to Microsoft in 2005 (working first as a SDET on the CLR and more recently in the Foundations for Software Engineering group in Microsoft Research)
the project was opensourced under Andy Stopford.
The current lead of MbUnit, Jeff Brown, also leads the Gallio Project. Since Gallio is the foundation of MbUnit v3, many MbUnit committers also work on Gallio and vice-versa.
The projects regular commit members are listed here and here.
These are just a few projects and companies who are currently using MbUnit:
