How to prevent logging noise during startup in @SpringBootTest?
Edited
Create logback-test.xml in your test resource (\test\resources), Then put bellow snippet into it
<configuration>
<include resource="org/springframework/boot/logging/logback/base.xml" />
<logger name="org.springframework" level="OFF"/>
</configuration>
It prints default system INFOs, not startup noise logs. (As you wanted)
And dependency of test can be as follows
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
You will need to create one logback-test.xml in your \test\resources directory, contents of this file can be following
<?xml version="1.0" encoding="UTF-8"?>
<configuration />
Why empty ?
Because you'd not want anything to be logged at this point in time, hence - empty configuration.
If you wish to find out more specific you can see some examples here
First of all: I know, this is not a real answer, but way too long for a comment.
Using the log4j dependency didn't changed much in my output.

My application.properties is empty, so no log config there.
My test
package com.example.demo;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "logging.level.root=")
public class DemoApplicationTests
{
@Test
public void test()
{
System.out.println("Katzenbilder sind doof");
}
}
Running the tests from within IntelliJ with logging.level.root=OFF
leads to this output

Process finished with exit code 0
The two lines with #####
are System.out.println() from a test bean.
Running the test with logging.level.root=INFO
I get the expected clutter of Spring log messages.
I also, just for the sake of validation, put logging.level.root=INFO
in my application.properties and had it to OFF
in the test. No clutter, just the System.out.println() messages.
