Disable excesive logging in Spring Boot JUnit Integration Tests

2015/03/26

SpringBoot

This was a major annoyance at first and couldn't find it anywhere, so when you want to write a SpringJUnit test for let's say Spring controller in Spring Boot similar to this:

		@RunWith(SpringJUnit4ClassRunner.class)
		@WebAppConfiguration
		@ContextConfiguration(classes = {Application.class})
		public class IntegrationTest {
		}

You might be surprised by the unnecessary amount of logging messages that cannot be tamed by your application.properties file. The culprit is logback library, so just put in test/resources/logback-test.xml this configuration and you should be good:

		<?xml version="1.0" encoding="UTF-8"?>

		<configuration scan="true">
			<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
				<encoder>
					<charset>utf-8</charset>
					<Pattern>[%p] %c - %m%n</Pattern>
				</encoder>
			</appender>
			<logger name="ch.erni.community.ideasboard" level="DEBUG"/>
			<logger name="org.springframework" level="OFF"/>
			<logger name="org.apache.catalina.startup.DigesterFactory" level="OFF"/>

			<root level="WARN">
				<appender-ref ref="CONSOLE"/>
			</root>

		</configuration>

This is something that I will return to in the future, so I just wanted to have it here.
