我正在编写一个应用程序,用户可以在其中更改(在运行时)存储log4net日志的目录。目录字符串存储在app.config中
当我想测试是否使用NUnit在正确的目录中创建日志文件时,不会创建日志文件(和相应的目录)。
在网上查找此问题时,我读到NUnit会停止日志记录,因为它使用log4net本身。提供的示例告诉您创建一个额外的.config(Test.config),它还包含log4net部分并在测试类中加载配置,我这样做了。
使用单元测试时仍然没有创建日志文件
启动应用程序时,将按原样创建日志文件。
设置日志目录的方法:
public void MyMethod()
{
string logDirectory = app.Settings["LogDirectory"].Value;
//assure that the file name can be appended to the path
if (!logDirectory.EndsWith(@"\"))
{
logDirectory += @"\";
}
//find the rolling file appender and set its file name
XmlConfigurator.Configure();
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();
foreach (IAppender appender in hierarchy.Root.Appenders)
{
if (appender is RollingFileAppender)
{
RollingFileAppender fileAppender = (RollingFileAppender)appender;
string logFileLocation = string.Format("{0}Estimation_Protocol_{1}.txt",
logDirectory, EstimatorHelper.SoftwareVersionAndDateTime());
fileAppender.File = logFileLocation;
fileAppender.ActivateOptions();
break;
}
}
log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
log.Debug("Logging directory & file name set.");
}
测试类:
class EstimatorTests
{
private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
public EstimatorTests()
{
FileInfo fileInfo = new FileInfo(@"%property{LogName}");
log4net.Config.XmlConfigurator.Configure(fileInfo);
}
[Test]
public void TestLoadInputPaths()
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection app = config.AppSettings;
string time = DateTime.Now.Ticks.ToString();
app.Settings["ProcessingProtocolDirectory"].Value = "C:\\thisFolderDoesntExist" + time;
Form mainForm = new Form();
Form.MyMethod();
Assert.IsTrue(Directory.Exists("C:\\thisFolderDoesntExist" + time));
//this assert fails!
}
}
log4net config:
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="%property{LogName}" />
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="5"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %logger - %message%newline%exception%newline"/>
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>

我没有对其进行测试,但我认为您需要删除XmlConfigurator.Configure();
中对MyMethod
的调用,因为这会覆盖您在测试类中执行的配置。
