If you're using SLF4J/Log4j in Maven you can shut off those messages by
creating a log4j.properties or log4j.xml file and putting it in
src/test/resources. (or in src/main/resources if you want it applied to code
other than your unit tests) Here's an example of the contents that could go
into log4j.xml :

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/";>

    <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="conversionPattern" value="%d{ISO8601} [%t] %-5p %c
%x - %m%n" />
        </layout>
    </appender>

    <logger name="org.mbari.vcr">
        <level value="error" />
    </logger>

    <root>
<!-- Values can be "debug|info|warn|error" -->
        <priority value="error" />
        <appender-ref ref="CONSOLE" />
    </root>
</log4j:configuration>
