/// An assembly level attribute that indicates that a given type implementing <see cref = "ITestRunCallback"/> should be subscribed to updates on the test progress. You can invoke the callbacks with [NUnit](http://www.nunit.org/) `ITest` and `ITestResult` classes.
///
/// At the `RunStarted` and `RunFinished` methods, the test and test results are for the whole test tree. These methods invoke at each node in the test tree; first with the whole test assembly, then with the test class, and last with the test method.
///
/// From these callbacks, it's possible to read the partial or the full results, and to save the XML version of the result for further processing or continuous integration.
