bash script simple auto deployment with svn and phpunit

Question

I am trying to build simple deployment system with bash script. I have tried checking TeamCity and similar products, but they are too difficult and needs lots of time to understand configure ect. So my idea is to create bash script which:

1. connect to server using ssh
2. get current revision
3. svn update
4. run unit tests
5. if tests failed -> svn up -rXXX

What I have achieved: I am running sshpass -p 'pass' ssh user@IP "svn up; sh tests.sh"; which downloads commited changes to my server and runs all phpunit test.

The problem is that if my tests fail I need to revert chainges manually. I could get current revision using svn info | grep "Revision" | awk '{print $2}' and get bask to it, but I cannot find the way to check if tests failed in tests.sh. Anyone has any ideas how to achieve this? Or maybe you have better suggestions to achieve same results?

I have built it using @gontrollez hint. ./deploy script:

reset; 
sshpass -p 'pass' ssh dev@IP "./update";
RET=$?;
if [ $RET -eq 0 ];then
    sshpass -p 'pass' ssh test@IP "./update";
    RET=$?;
    if [ $RET -eq 0 ];then      
        sshpass -p 'pass' ssh prod@IP "./update";
        RET=$?;
        if [ $RET -eq 0 ];then      
            reset;
            echo "$(tput setaf 2)Success!"
        else
            echo "$(tput setaf 1)PROD test failed!"
        fi
    else
       echo "$(tput setaf 1)TEST test failed!"
    fi
else
   echo "$(tput setaf 1)DEV test failed!"
fi
echo "$(tput sgr0)"

./update script:

current=$(svn info | grep "Revision" | awk '{print $2}');
svn up;
sh tests.sh;
OUT=$?;
if [ $OUT -eq 0 ];then      
    echo "Update successful!"
else
    echo "Test failed! Reverting...";
    svn up -r$current;
    $(exit 10);
fi

And tests.sh runs phpunit tests
