Hi Charlie,

I do not believe that it is a bug at all. I have provided two solutions in my blog post
http://do-the-right-things.blogspot.com/2010/11/log4net-configuration-issue-when-using.html

In short, it is because NUnit contains code in
NUnit.Core.Log4NetCapture.StartCapture() that causes log4net to
construct a default repository without finding the user's specified
config file. Full technical disclosure is found on my blog post.

The way to over come this is to put a key="log4net.Config" in the
<appSettings> in the NUnit project's config file and in the value
specify the log4net config file. With this simple specifiication, NUnit
2.5.7 will work just fine.

Rover.

Log4net not working with NUnit

Status in NUnit V2 Test Framework: Triaged

Bug description:
Problem: Using log4net with newer versions of nunit means that no
log file is created.

Demonstration follows.

I created the solution in VS 2008.
The OS is Windows XP.
I tested using both the nunit GUI and console.
I compared Nunit 2.2.5 with 2.5.5 (I suspect 2.5.0 will fail as well.)
The solution is created as a console app.

When the app is run as a console application a Log file is produced.
When the app is run using 2.2.5 a Log file is produced.
When the app is run using 2.5.5 no Log file is produced.

There are two files in the solution: Log.config and Program.cs

Following comes from a file name "Log.config"

----------------------------------------------
<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="false">       

  <appender name="DefaultLogFile" type="log4net.Appender.RollingFileAppender">
      <file value=".\Log" />
      <appendToFile value="false" />
      <staticLogFileName value="false" />           
      <rollingStyle value="Date" />
      <datePattern value="'.'yyyyMMdd'.log'" />
      <layout type="log4net.Layout.PatternLayout">
      
        <conversionPattern value="%utcdate{ABSOLUTE} %-5level %message%newline" />
        
      </layout>
  </appender>

  <root>
    <level value="All" />
    <appender-ref ref="DefaultLogFile" />
  </root>
</log4net>
-----------------------------------------------------

Following is Program.cs

-----------------------------------------------------
using System;
using System.Reflection;
using NUnit.Framework;

[assembly: log4net.Config.XmlConfiguratorAttribute(ConfigFile = "Log.config", Watch = true)]

namespace TestNunitLog4net
{
[TestFixture]
public class Program
{
  private static readonly log4net.ILog log 
        = log4net.LogManager.GetLogger(
            MethodBase.GetCurrentMethod().DeclaringType);
            
  // Test scenarios
  //   Test 1: Works - log show up (gui and console)
  //        log4net: 1.2.10.0
  //        Nunit: 2.2.5.0

  //   Test 2: Fails - no log file (gui and console)
  //        log4net: 1.2.10.0
  //        Nunit: 2.5.5.10112
  
  // Following has no impact.
  // It exists just so we can see it in log.
  private readonly String exeType;
  
  static void Main()
  {
    Program p = new Program("Exe");
    p.TestLog();
  }
  
  private Program(String stype)
  {
    this.exeType = stype;
  }
  
  public Program()
  {
    this.exeType = "Nunit";
  }


  [Test]
  public void TestLog()
  {
    log.Debug(exeType + ": First line");
    log.Debug(exeType + ": Second line");
  }

} // End of class
} // End of namespace
