How to change the level of output in Spring Boot

Problem: When I’m testing my Spring application hundreds of lines of log code appear (DEBUG level).

The quantity of log is particularly important using Spring integration.

According to the spring documentation it should be possible to set the level of debug in the but the level of logs did not change.

The solution is to create a logback.xml in the classpath of the test ([PROJECT_ROOT]/src/test/resources):

<?xml version="1.0" encoding="UTF-8"?>
	<include resource="org/springframework/boot/logging/logback/base.xml"/>
	<logger name="org.springframework" level="INFO"/>

Before and after the change
