Re: GUI extreme slowness due to log4net

I too am having problems with logging and NUnit. My application uses
NHibernate, which has very verbose logging that results in the unit tests
running 100x (or more) slower than without the log2net logging.
 
Our build server has a slightly older version of NUnit and tests are
practically instantaneous, even with data layer tests that set up and tear
down the database for each test. I'm very afraid of upgrading NUnit there
due to the logging.
 
I don't understand log4net and its configuration very well, but I can't seem
to find a way to stop the NUnit GUI from reporting all the NHibernate
logging.
 
Does anyone have a suggestion?
 
Richard

Hi

These tests ran fine in a previous version of nunit because there was not
the clash of use of log4net.  Is there something else I have to disable in
the config file?

I have tried creating a specific config file and nominating that in the
Project definition screen.  This does not seem to make any difference.all
the debug logging is obviously still occurring.  If I turn all the debug
logging on within Visual Studio it is slow as well but that would be
expected.  I can get the logs not to display (by turning off the log tab)
but that does not seem to disable the logging (ie to make the tests faster).


 

The config file I am editing is the default one nominated by nunit and in
the same directory as the assembly being tested.  I get very minimal output
displayed in the GUI.  The run time in the GUI for 6 tests was 224.09
whereas the same 6 tests ran within Visual Studio in 8.34 secs.significantly
different.

 

The log4net entry in my config file which I edit after Visual Studio has
created one specifically for the assembly is:

  <log4net>

    <appender name="Console" type="log4net.Appender.ConsoleAppender">

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

        <conversionPattern value="%class %level - %message%newline"/>

      </layout>

    </appender>

    <root>

      <level value="ERROR"/>

      <appender-ref ref="Console"/>

    </root>

    <logger name="RadicaLogic.Framework">

      <level value="ERROR"/>

    </logger>

    <logger name="RadicaLogic.Terminology">

      <level value="ERROR"/>

    </logger>

  </log4net>

 

I have also tried simplifying it by removing 

    <logger name="RadicaLogic.Framework">

      <level value="ERROR"/>

    </logger>

    <logger name="RadicaLogic.Terminology">

      <level value="ERROR"/>

    </logger>

 

I still get extremely slow performance in the nunit GUI.

Hi Di,

 

When you say, "default App.config" are you refering to the one used by your
executable? If so, you need to do the same thing in the config for your
tests.

 

However, it's possible that this may not do the job, since the appender used
by the tests is created programmatically. If you verify that the test config
is correct and the problem is still there, please file a bug.

 

Charlie

Hi

When I run the tests within visual studio, they run very quickly but within
the GUI they are EXTREMELY slow.  This seems to be due to the fact that all
DEBUG messages are still being generated and  captured not filtered even if
my default App.config does have them set to INFO.  Can you suggest how to
fix this in the GUI?

 

Thanks.Di
