Java 多线程JBehave日志

虽然多线程jBehave运行非常清晰，
我不清楚如何处理乱七八糟的日志记录

这里有什么选择

将应用程序的输出重新定向到std out（JBehave的输出已经存在）。注意

follow=true

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.follow=true
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %-64.64C %4L | %m%n

log4j.rootLogger=error, stdout
log4j.logger.com.company.app.interesting.module=debug
...

每线程文件输出

因此，每个并行测试都会有一个日志文件，该日志文件同时具有测试输出和应用程序输出（只有测试运行线程执行的代码）。
奖金-TeamCityReporter（JBehave-to-TC集成）将实时成功统计运行的并行测试，并在TC GUI上报告任何测试失败。将测试输出目录配置为TC工件路径，以访问每个测试输出

将应用程序的输出重新定向到std out（JBehave的输出已经存在）。注意
