Using ReSharper, how to show debug output during a long-running unit test?

Question

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

XunitLogger uses AsyncLocal to keep track of the logging context so calls to Trace.Writeline and Console.Writeline can be routed to the correct instance of ITestOutputHelper.

Usage:

static class ClassBeingTested
{
    public static void Method()
    {
        Trace.WriteLine("From Trace");
        Console.WriteLine("From Console");
        Console.Error.WriteLine("From Console Error");
    }
}

public class TestBaseSample  :
    XunitLoggingBase
{
    [Fact]
    public void Write_lines()
    {
        WriteLine("From Test");
        ClassBeingTested.Method();

        var logs = XunitLogger.Logs;

        Assert.Contains("From Test", logs);
        Assert.Contains("From Trace", logs);
        Assert.Contains("From Console", logs);
        Assert.Contains("From Console Error", logs);
    }

    public TestBaseSample(ITestOutputHelper output) :
        base(output)
    {
    }
}
