Log files rotate when they reach 10 MB and, as with console output, ERROR-level, WARN-level, and INFO-level messages are logged by default. Size limits can be changed using the logging.file.max-size property. Previously rotated files are archived indefinitely unless the logging.file.max-history property has been set.

More customization you can do for logging, please refer Spring Boot Logging

There is no way to set an unlimited size as such, but there is a workaround
You can set a huge limit for the max size, like this: 

logging.file.max-size: 100000GB

Set this in application.yml or application-test.yml
If your machine has more than 100,000 GB of disk space, you can use a higher number ;].

Background:
Spring boot loads this default config file: org/springframework/boot/logging/logback/base.xml
That file includes: org/springframework/boot/logging/logback/file-appender.xml
Which uses SizeAndTimeBasedRollingPolicy

add below in your logback.xml

<timeBasedFileNamingAndTriggeringPolicy
            class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>5MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
