I have a console app reading data from Console.ReadLine().
Is there any way to benchmark the app?

Hi @BigSquareHasNoEdge

Since #2092 (will be released soon as part of 0.13.13) we don't redirect the standard input of the benchmark process. In theory this should make it possible for you to overwrite standard input as part of [GlobalSetup] by using Console.SetIn and let you use Console.Read* methods in your benchmarks.

If this does not work you could redesign your code and feed it with System.IO.TextReader instance. This should make it also unit-testable.
