How can I write output from a unit test?

Question

Any call in my unit tests to either Debug.Write(line) or Console.Write(Line) simply gets skipped over while debugging and the output is never print

Answer 1

I think it is still actual.

You can use this NuGet package: Bitoxygen.Testing.Pane

Call the custom WriteLine method from this library. It creates a Testing pane inside the Output window and puts messages there always (during each test, it runs independently of DEBUG and TRACE flags).

To make tracing more easy I can recommend to create a base class:

[TestClass]
public abstract class BaseTest
{
    #region Properties
    public TestContext TestContext { get; set; }

    public string Class
    {
        get { return this.TestContext.FullyQualifiedTestClassName; }
    }
    public string Method
    {
        get { return this.TestContext.TestName; }
    }
    #endregion

    #region Methods
    protected virtual void Trace(string message)
    {
        System.Diagnostics.Trace.WriteLine(message);

        Output.Testing.Trace.WriteLine(message);
    }
    #endregion
}

[TestClass]
public class SomeTest : BaseTest
{
    [TestMethod]
    public void SomeTest1()
    {
        this.Trace(string.Format("Yeah: {0} and {1}", this.Class, this.Method));
    }
}
