scalatest - 从 Maven 运行测试时禁用 scalatest 日志记录语句

Question

禁用 scalatest log4j 消息日志记录的方法是什么:

log4j.properties如下:

log4j.rootLogger=INFO,CA,FA

#Console Appender
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%d{HH:mm:ss.SSS} %p %c: %m%n
log4j.appender.CA.Threshold = INFO


#File Appender
log4j.appender.FA=org.apache.log4j.FileAppender
log4j.appender.FA.append=false
log4j.appender.FA.file=target/unit-tests.log
log4j.appender.FA.layout=org.apache.log4j.PatternLayout
log4j.appender.FA.layout.ConversionPattern=%d{HH:mm:ss.SSS} %p %c{1}: %m%n
log4j.appender.FA.Threshold = INFO

..
log4j.logger.org.scalatest=WARN

但是我们看到 INFO 级别的 scalatest log4j 消息:

2014-11-30 14:25:57,263 INFO  [ScalaTest-run-running-DiscoverySuite] Configuration.deprecation (Configuration.java:warnOnceIfDeprecated(840)) - hadoop.native.lib is deprecated. Instead, use io.native.lib.available
2014-11-30 14:25:57,493 INFO  [ScalaTest-run-running-DiscoverySuite] hbase.HBaseCommonTestingUtility (HBaseTestingUtility.java:startMiniCluster(840)) - Starting up minicluster with 1 master(s) and 2 regionserver(s) and 2 datanode(s)
2014-11-30 14:25:57,499 INFO  [ScalaTest-run-running-DiscoverySuite] hbase.HBaseCommonTestingUtility (HBaseTestingUtility.java:setupClusterTestDir(390)) - Created new mini-cluster data directory: /shared/hwspark/target/

Answer 1

或者，您可以将这段代码扔到测试中的任何位置，

org.slf4j.LoggerFactory.getLogger(org.slf4j.Logger.ROOT_LOGGER_NAME)
  .asInstanceOf[ch.qos.logback.classic.Logger]
  .setLevel(ch.qos.logback.classic.Level.WARN)

这会将所有日志记录设置为WARN级别。
