Does anyone use MSTest and if so, have you had success in getting logging to work with your tests?

Normally, in my application log4net is configured by a call to:

   log4net.Config.XmlConfigurator.Configure(logConfigFile);

But, I’m writing tests for one of my library projects, so I don’t see a good place to put such a statement.

I thought I would try using the assembly attribute and an app.config file to configure log4net, but this doesn’t seem to work.

In a file called “Logging.cs” I have this;

using log4net.Config;

[assembly: XmlConfigurator()]

And my app.config looks like this:

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

<configuration>

  <configSections>

    <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

      <section name="SNIP.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />

    </sectionGroup>

    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

  </configSections>

  <userSettings>

    <SNIP.Properties.Settings>

      <setting name="DefaultEnvironmentPath" serializeAs="String">

        <valueSNIP\env\unittest</value>

      </setting>

      <setting name="ConfigurationFilename" serializeAs="String">

        <value>SNIP.config.xml</value>

      </setting>

      <setting name="Log4NetConfigurationFilename" serializeAs="String">

        <value>log4net.config.xml</value>

      </setting>

    </SNIP.Properties.Settings>

  </userSettings>

  <log4net>

    <appender name="DetailedAppender" type="log4net.Appender.FileAppender, log4net">

      <file type="log4net.Util.PatternString" value="log4net.log" />

      <appendToFile value="false" />

      <layout type="log4net.Layout.PatternLayout">

        <conversionPattern value="%date %-5level %logger - %message%newline" />

      </layout>

    </appender>

    <root>

      <level value="INFO" />

      <appender-ref ref="DetailedAppender" />

    </root>

    <logger name="NHibernate">

      <level value="WARN" />

    </logger>

  </log4net>

</configuration>

Actually it is working!  But the file isn’t where I thought it would be (in the TestResults\out folder)

It was actually written to:

C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\log4net.log

So the working directory is not the “out” directory as I had assumed.  Okay, well at least it is working!
