Maven - single way to know if tests are skipped

With Maven, there is more than one way to skip running unit and/or integration tests.

For example:

• mvn clean package -DskipTests (Tests are compiled, but not run)
• mvn clean install -Dmaven.test.skip (Tests are neither compiled nor run)

If I'm trying to activate a profile based on the fact that tests are being skipped, how could I reliably do that?

I can activate a profile based on absence of one property, but not two:

    <profile>
        <id>do-something-because-tests-are-skipped</id>
        <activation>
            <property>
                <name>!skipTests</name>
            </property>
            <property>
                <name>!maven.test.skip</name> <!-- Two properties doesn't work -->
            </property>
        </activation>
        <build>
        .....
        </build>
    </profile>

Is there some other way to achieve the desired behaviour?

This has now been implemented in Maven 4.0.0-rc-1

<profile>
    <id>do-something-because-tests-are-skipped</id>
    <activation>
        <condition>
            <![CDATA[
                not(${skipTests}) && not(${skipITs}) && not(${maven.test.skip})
            ]]>
        </condition>
    </activation>
    <build>
    .....
    </build>
</profile>
