Running selective unit tests in VS 2012 using TestCaseFilter

This post details the implementation and usage of the `TestCaseFilter` feature in Visual Studio 2012's new unit testing platform. It explains how to use `vstest.console.exe`, Team Build, and the Test Platform Client API to specify filtering expressions. The post outlines the supported operators (=, !=, ~, &, |) and properties (Name, FullyQualifiedName, Priority, TestCategory, ClassName) for the MSTest adapter, along with code examples for using the `ITestCaseFilterExpression` interface within test adapters.
