Timeout for Maven Tests

We need a way to somehow set a timeout for junit tests within the maven-test-plugin. Something like "maven.junit.timout" would be very nice. It doesn't yet exist. Is there another way to tell him how long he should wait for test to complete? I know that in the junit.properties-file you can set "junit.timout", but the file automatically created in this case, i think...

ttyl + thank you very much
