Why in the world does the following test fail? (its in xunit) I've tried it with different appenders and it never writes anything though the log seems like it is ready to write. I eventually created my own appender just to test it.
public class TestAppender : AppenderSkeleton {
public event Action<LoggingEvent> AppendCalled = delegate { };
protected override void Append(LoggingEvent loggingEvent) {
AppendCalled(loggingEvent);
}
}
public class Class1 {
private TestAppender _appender = new TestAppender();
public Class1() {
log4net.Util.LogLog.InternalDebugging = true;
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();
Logger rootLogger = hierarchy.Root;
rootLogger.Level = Level.All;
Logger coreLogger = hierarchy.GetLogger("abc") as Logger;
coreLogger.Level = Level.All;
coreLogger.Parent = rootLogger;
PatternLayout patternLayout = new PatternLayout();
patternLayout.ConversionPattern = "%logger - %message %newline";
patternLayout.ActivateOptions();
_appender.Layout = patternLayout;
_appender.ActivateOptions();
coreLogger.AddAppender(_appender);
}
[Fact]
public void Test() {
bool called = false;
_appender.AppendCalled += e => called = true;
var log = LogManager.GetLogger("abc");
log.Debug("This is a debugging message");
Thread.Sleep(TimeSpan.FromSeconds(2));
log.Info("This is an info message");
Thread.Sleep(TimeSpan.FromSeconds(2));
log.Warn("This is a warning message");
Thread.Sleep(TimeSpan.FromSeconds(2));
log.Error("This is an error message");
Assert.True(called);
}
}
