如何在执行 MSTest 测试期间写入 Console.Out

根据 Marty Neal 和 Dave Anderson 的评论:

使用系统；使用 System.Diagnostics；...Trace.Listeners.Add(new TextWriterTraceListener(Console.Out));//或 Trace.Listeners.Add(new ConsoleTraceListener());Trace.WriteLine("Hello World");

Context:
We have some users reporting issues with a file upload feature in our web application. It only happens occasionally and without any special pattern. We have been trying to figure it out for a long time, adding debug information anywhere we can think it might help, crawling the logs etc, but we have not been able to reproduce or figure it out.

Problem:
I'm now trying to reproduce this by using MSTest and WatiN to repeat the operation that is supposed to fail a large number of times (several hundreds). Just to have a clue about how far in the loop the test has gotten, I want to print something like:

Console.WriteLine(String.Format("Uploaded file, attempt {0} of {1}", i, maxUploads));

This does however not appear in the Output window. Now I know that you'll get the console output in the test results (as well as what you output from Debug.Writeline etc), but this is not available until after the test has finished. And since my test with hundreds of repetitions could take quite some time, I'd like to know how far it has gotten.

Question:
Is there a way I can get the console output in the Output window during test execution?

The Console output is not appearing is because the backend code is not running in the context of the test.

You're probably better off using Trace.WriteLine (In System.Diagnostics) and then adding a trace listener which writes to a file.

This topic from MSDN shows a way of doing this.

According to Marty Neal's and Dave Anderson's comments:

using System;
using System.Diagnostics;

...

Trace.Listeners.Add(new TextWriterTraceListener(Console.Out));
// or Trace.Listeners.Add(new ConsoleTraceListener());
Trace.WriteLine("Hello World");
