junit测试时控制台未输出日志，日志文件中也没有任何内容

Question

目前学到4-5课，在用junit测试service层时，报错的日志信息没有输出到控制台和日志文件，ImageUtil工具类里的日志信息也没有任何输出，正常运行时控制台输出内容如下

2019-02-25 23:36:05.592 [main] INFO o.s.t.c.support.DefaultTestContextBootstrapper - Loaded default TestExecutionListener class names from location [META-INF/spring.factories]: [org.springframework.test.context.web.ServletTestExecutionListener, org.springframework.test.context.support.DirtiesContextBeforeModesTestExecutionListener, org.springframework.test.context.support.DependencyInjectionTestExecutionListener, org.springframework.test.context.support.DirtiesContextTestExecutionListener, org.springframework.test.context.transaction.TransactionalTestExecutionListener, org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener]

本应打印出来的保存路径并没有出现。

不过在使用ImageUtil里的main方法测试时却能在控制台输出logger打印的日志。
logback.xml文件是直接复制了课件的内容，应该是没有问题

同学好，请问你这边异常情况下不打印日志，请问日志是如何记录错误并输出的呢？并且其实ut很多情况下并不需要打印日志呢，因为直接设置断点调试即可，现在关注点是项目真正执行的时候能否打印出日志，如果不行，并且是复制的课程日志配置的话，建议把jar包对齐一下，清除相关jar重新update maven project试试

  我尝试用logger.error()，log.warn()，logger.info()，logger.debug()输出四个级别日志，发现控制台只有debug级别的不会输出，而日志文件则没有生成。

  是说测试的时候输出不了日志吗，如果是的话，需要在测试的src/test/resources里面添加对应的logback.xml配置。

  谢谢老师，现在控制台打印日志已经正常了。刚刚注意到日志文件其实是有输出且有内容的，但是没有输出到配置文件里所指定的路径下，测试的时候生成了一个名为catalina.base_IS_UNDEFINED的文件夹，日志文件都输出到这里了，不知道要怎么修改
