Can not print from NUnit unit test

Question

I have the following test:

    [Test]
    public void RetrieveWrongURL()
    {
        Debug.WriteLine("In RetrieveWrongURL");
        Console.WriteLine("In RetrieveWrongURL");
        Assert.Throws<IncorrectUrlSuppliedException>(() => mRetriever.doSomething("https://someWrong.url"));
    }

When I am running the test, in the Output window I am getting:

[05/01/2018 10:23:40 Informational] ------ Run test started ------
[05/01/2018 10:23:41 Informational] NUnit Adapter 3.9.0.0: Test execution started
[05/01/2018 10:23:41 Informational] Running selected tests in Z:\path\to\my\dll\MyDll.dll
[05/01/2018 10:23:41 Informational] NUnit3TestExecutor converted 3 of 3 NUnit test cases

[05/01/2018 10:23:42 Informational] ========== Run test finished: 1 run (0:00:02.0995689) ==========

How can I write anything to the output window?

Try the following:

NUnit.Framework.TestContext.WriteLine("text");

NOTE: The NUnit console displays text output from tests at the end of each test. A summary report is produced at the end of the test run. This has been the case since NUnit 3.0. Before that, output was sent to the console immediately as it was produced.

Use this

System.Diagnostics.Debug.WriteLine("something");

Or you can use Trace.WriteLine and get the output in the test runner even in Release. – Adam Brown Jan 05 '18 at 10:43
