Subject: Make sure tests work with dash as well.
X-Git-Url: http://git.grml.org/?p=grml-unittests.git;a=commitdiff_plain;h=30600052dc7c9c15a0639f3417d75b70e36cef81;hp=980f66f4a42c6a3562c9c4b360a0a0e0f96fa829

Make sure tests work with dash as well.

If dash is used as /bin/sh then $RANDOM isn't set.
Running all the runit.sh scripts using zsh as well addresses this issue,
also check for $RANDOM in framework.sh so we exit before running into
obscure error messages.
