Answer 1

In Visual Studio 2017, in the Test Explorer window, there is a link, Output, in the lower Test pane. This brings up anything written to the console during that unit test.

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.

Answer 4

Use the Test-Output view.

Steps:

1. Open Test Explorer
2. Select any particular test
3. Run it if it has never been run.
4. Click on the output link on the test results pane.

There is isn't any need to replace Console.WriteLine with anything as this view logs messages from:

Console.WriteLine

Trace.WriteLine

Debug.WriteLine

TestExplorer.Out.WriteLine

Answer 5

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

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