Replace Console.WriteLine in NUnit

Question

I haven't done much with NUnit before, but I just wanted to dump some text to a window in a console type fashion. For example:

Console.WriteLine("... some information...");

That won't work of course because NUnit is driving things.

I'm in the middle of building some unit tests and want to dump a list of variable values for inspection during debug. It isn't strictly a unit test if I need to do this, I admit that, but it would be convenient.

Answer 1

In NUnit v3, you can also write to the test results output for debugging with

TestContext.Out.WriteLine("Message to write to log");

Answer 2

You can see the console output. You just have to select the "Text Output" tab in the NUnit GUI runner.

If you are using the ReSharper test runner, the console output should be displayed. Ensure that the test runner output window is displayed by clicking the "Show Output" button in the test runner tool bar:

You should then get something as follows:

Answer 3

Try using System.Diagnostics.Debug.WriteLine instead.
