Even though I have awarded the bounties to the users below that have attempted to help, the original question remains unanswered. No actual workable solution exists to ensure that the logback.groovy configured logging is honoured within the junit tests. The tests load up the logback config and it does report the correct level and yet still the actual test logging (exclusively through slf4j) is at ANY or TRACE level

I know others have encountered this same problem and it is very annoying when tests for big projects take a lot longer due to console logging being much too verbose. I cannot keep throwing bounties at this question. I hope someone comes up with a good solution that allows the tests logging to be properly configured at different levels through a system property. Then, different configurations can be created for the project so that tests will be able to configured at different logging threshold levels.

我的日志记录是通过 logback.groovy 文件由 logback 配置的

现在，当我聚合所有其他项目的 Maven POM 项目启动时，它会将所有系统属性传递给它们以设置正确的日志记录级别。

但是，当 junit 测试运行时，出于某种原因，即使测试类静态 @beforeClass 确保正确配置了 logback，记录器也不会选择正确的级别。

问题不在于测试中的记录器，——好吧——是的，它们也是——，真正的问题是运行的代码部分中的记录器(我所有的程序记录器无处不在)是设置为错误的日志记录级别。当配置程序测试时，他们没有选择日志记录是什么。

但是，当 logback 使用 logback.goovy 文件初始化时，项目报告正确。但是，实际的日志记录级别设置为 TRACE 或 ALL

从下面的输出中可以清楚地看出，logback 已配置为 INFO。但是 TRACE 的第一个项目日志记录语句(最后一行)显示没有被拾取。

帮助。

最佳答案

我在 junit 测试中也遇到了类似的问题。 我找不到好的解决方案。我使用了以下解决方法:

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
import org.slf4j.LoggerFactory;
...
static Logger logger;
static{
   // Logger.ROOT_LOGGER_NAME == "ROOT"
   logger = ((Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME));
   logger.setLevel(Level.INFO);
}

...

我认为在你的情况下，库以某种方式使用它自己的 ConsoleAppender 实例，其名称不是“STDOUT”。 我希望设置根日志级别可以解决问题。

root(loglevel, ['ROOT']);
