防止Log4Net寫入NUnit文本輸出窗口

Question

當我運行單元測試時，我使用_.P("My Test Message");將信息打印到NUnit中的文本輸出窗口。

但是我的消息被Log4Net消息所淹沒。

我想從我的NUnit文本輸出中刪除Log4Net消息。

Log4Net被配置爲僅寫入文件。

<log4net debug="true"> 
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> 
    <file value="Log.txt" /> 
    <appendToFile value="true" /> 
    <rollingStyle value="Size" /> 
    <maxSizeRollBackups value="10" /> 
    <maximumFileSize value="10MB" /> 
    <staticLogFileName value="true" /> 
    <param name="DatePattern" value="yyyyMMdd" /> 
    <layout type="log4net.Layout.PatternLayout"> 
     <conversionPattern value="%-5p %d - %m%newline" /> 
    </layout> 
    </appender> 

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

1日運行單元測試，我得到以下輸出

Answer 1

根據在log4net.sourceforge.net一些快速的研究，這個片段下方啓用了調試輸出（System.Diagnostics.Debug），這NUnit的也將回暖。如果你刪除debug="true"，你應該得到你想要的行爲。

<log4net debug="true">
