The popular .NET automation and test framework, Gallio and MbUnit have a new release available. This release includes many new features and performance enhancements, including parallelizable tests, one-click test debugging, and ReSharper 4.5 support.
Pex is a white-box test generation tool from Microsoft Research. Instead of hand-writing a separate test case for each execution path within a given method, Pex allows a developer to write a single parameterized test method, which Pex will use to generate a suite of standard unit tests to exercise paths within the target method.
Gallio is an automation platform targeting .NET test frameworks. Instead of each test framework creating its own toolset, including an automation API and test runner, Gallio seeks to provide a neutral, extensible platform with tools and automation services that can be leveraged by any test framework.
The White project is an automated testing framework for Win32, WinForm, WPF and SWT (java) applications. Use it in combination with your favorit xUnit framework just like WatiN to perform user acceptance testing.
