如果我理解你的需求正确,这可以通过组合以下来实现:使用JUnit的方法规则,将
- 给你目前的方法
- 在运行时创建一个Log4j追加,并与方法的名称配置它的名字获得你刚刚获得
具体来说,您需要创建一个自定义的JUnit规则。我选择了延长TestWatcher
,因为它一旦你有了这个,你可以把它作为你的测试类中的规则似乎是最合适的
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;
}
}
。规则只是测试中的一个字段(带有@Rule
注释)。在这里,我把它称为rule
(我不承认,这不是很有想象力)。为了从您的测试方法登录,您需要拨打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);
}
}
当我运行这个测试我~/Desktop/Selenium/AutomationLogs
目录下创建了这两个文件:
productOfTwoInts_2015-05-10
sumOfTwoInts_2015-05-10
的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
当你说
“测试名称“是指测试方法的名称还是测试类的名称? –
