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

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

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

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

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

<?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.

1.3 Turn off the Spring banner.

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

Done, the console should be empty now.
