我想在我的Selenium Java测试中添加日志记录。我已经实现了log4jFramework,它可以很好地将日志放在控制台或文件中。
我正在使用JUnit测试框架,我想在日志文件的文件名中包含测试名称和日期/时间,而不是使用标准约定,这似乎是在文件前面添加一个数字+1文件已存在。
这是我的log4j.properties文件...
log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=~/Desktop/Selenium/AutomationLogs/automationLog
log4j.appender.rollingFile.MaxFileSize=2MB
log4j.appender.rollingFile.MaxBackupIndex=2
log4j.appender.rollingFile.layout = org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} %p %t %c - %m%n
我在网上找到的内容似乎只与每日滚动文件相关。我想每次运行单元测试时都为日志生成一个新文件
答案 0 :(得分:7)
如果我理解你的需要,可以通过结合以下内容来实现:
具体来说,您需要创建自定义JUnit规则。我选择扩展TestWatcher
似乎是最合适的
import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.apache.log4j.Logger;
import org.apache.log4j.PatternLayout;
import org.apache.log4j.RollingFileAppender;
import org.junit.rules.TestWatcher;
import org.junit.runner.Description;
public class TestMethodLogging extends TestWatcher {
private static final String date = new SimpleDateFormat("y-MM-dd")
.format(new Date());
private Logger logger;
@Override
protected void starting(Description description) {
String name = description.getMethodName();
RollingFileAppender a = (RollingFileAppender) Logger.getRootLogger()
.getAppender("rollingFile");
PatternLayout layout = new PatternLayout();
layout.setConversionPattern("%d{dd MMM yyyy HH:mm:ss} %p %t %c - %m%n");
try {
File logDir = new File(a.getFile()).getParentFile();
File logFile = new File(logDir, name + "_" + date);
logger = Logger.getLogger(name);
logger.addAppender(new RollingFileAppender(layout, logFile
.getAbsolutePath()));
} catch (IOException e) {
throw new RuntimeException(e);
}
}
public Logger getLogger() {
return logger;
}
}
一旦你有了这个,你可以将它作为规则放在你的测试类中。规则只是测试中的一个字段(带有@Rule
注释)。在这里我称之为rule
(我承认不是很有想象力)。要从测试方法中记录,您需要致电rule.getLogger()
。
import static org.junit.Assert.assertEquals;
import org.junit.Rule;
import org.junit.Test;
public class MyTest {
@Rule
public TestMethodLogging rule = new TestMethodLogging();
@Test
public void sumOfTwoInts() throws Throwable {
rule.getLogger().error(
"logging to a logger whose name is based on the test method's name");
assertEquals(5, 2 + 3);
}
@Test
public void productOfTwoInts() throws Throwable {
rule.getLogger().error(
"logging to a logger whose name is based on the test method's name");
assertEquals(8, 2 * 4);
}
}
当我运行此测试时,它会在我的~/Desktop/Selenium/AutomationLogs
目录下创建这两个文件:
productOfTwoInts_2015-05-10
sumOfTwoInts_2015-05-10
第一个文件的内容如下所示:
$ cat productOfTwoInts_2015-05-10
10 May 2015 19:59:58 ERROR main productOfTwoInts - logging to a logger whose name is based on the test method's name
10 May 2015 20:01:22 ERROR main productOfTwoInts - logging to a logger whose name is based on the test method's name
10 May 2015 20:01:24 ERROR main productOfTwoInts - logging to a logger whose name is based on the test method's name
