The Gallio Automation Platform is an open, extensible, and neutral system for .NET that provides a common object model, runtime services and tools (such as test runners) that may be leveraged by any number of test frameworks.

Gallio ships with MbUnit v3, an extensible attribute-based unit testing framework, as well as adapters for several other popular testing frameworks and tools.

This document describes the Gallio and MbUnit v3 developer API and extensibility interfaces.

For additional user-oriented documentation content, tutorials and samples, please refer to the Gallio Book.
