Spring Boot Test – How to disable DEBUG and INFO logs

Run the Spring Boot integration test or unit test, many annoying DEBUG and INFO logs are displayed in the console.

P.S Tested with Spring Boot 2

Console

Solution

To disable the logs, turn off the logging.level in both application.properties and logback-test.xml

1.1 Turn off the logging in application.properties

application.properties

logging.level.org.springframework=OFF
logging.level.root=OFF

The DEBUG or INFO logs below the Spring banner are off now.

Console

2019-03-04 13:15:25.151  INFO   --- [           main] .b.t.c.SpringBootTestContextBootstrapper :

1.2 Create a logback-test.xml in src/test/resources. Again, turn off the logging here.

logback-test.xml

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

Good, just left the Spring banner.

Console

  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/
 :: Spring Boot ::        (v2.1.2.RELEASE)

1.3 Turn off the Spring banner.

application.properties

logging.level.org.springframework=OFF
logging.level.root=OFF
spring.main.banner-mode=off

Done, the console should be empty now.
