add below in your logback.xml

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

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

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
