I\'m using xUnit with the ReSharper test runner and the xUnitContrib resharper plugin.
When I have a long-running test, I\'d like to be able to output some progress
You may also consider using xunit.NLog which is a very nice and clean way to inject ITestOutputhelper into your SUTs.
xunit.NLog
ITestOutputhelper
