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.
The Gallio platform seeks to facilitate the creation of a rich ecosystem of interoperable testing tools produced by and for the community at large so as to address a far wider range of testing needs than any previous independent testing framework has done before. Unit tests, integration tests, performance tests, and even semi-automated test harnesses should all be able to leverage common facilities where appropriate. Moreover, they should present consistent interfaces to the world so that they can easily be integrated into the systems and processes of the enterprise.
At present Gallio can run tests from MbUnit versions 2 and 3, MbUnitCpp, MSTest, NBehave, NUnit, xUnit.Net, csUnit, and RSpec. Gallio provides tool support and integration with AutoCAD, CCNet, MSBuild, NAnt, NCover, Pex, Powershell, Resharper, TestDriven.Net, TypeMock, and Visual Studio Team System.
Gallio also includes its own command-line runner, Echo, and a Windows GUI, Icarus. Additional runners are planned or under development. Third parties are also encouraged to leverage the Gallio platform as part of their own applications.
Gallio has a rich plug-in model that enables integration with additional frameworks and tools of your own design. Tests can be implemented in almost any language or format provided that a suitable extension has been installed.
