I have a problem with test console output in IntelliJ 2016. When I run JUnit tests via IntelliJ, the console window is flooded with enormous amounts of log lines, for example
DEBUG reactor.ipc ....
DEBUG io.netty.buffer.ByteBufUtil ....
It's a simple Spring-Boot application which uses the default logging - I think it's slf4j. I tried setting
logging.level.reactor.ipc=WARN
in my src/main/resources/application.properties
and also setting
-Dlogging.level.root=WARN
on the RunConfig's VM arguments, but neither has any effect on the log output.
What is the correct place to configure logging verbosity when executing Tests from Intellij?
You can fill up file named logback.xml in src/test/resources with sample content like:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d %5p | %t | %-55logger{55} | %m %n</pattern>
</encoder>
</appender>
<root>
<level value="TRACE"/>
<appender-ref ref="CONSOLE"/>
</root>
</configuration>
to have TRACE logging level. You can change this log level to meet your needs.
