Hi @hussein-aitlahcen

What you are evaluating with forge test; echo $? is actually the exit code of echo

You can verify this by running:

forge test && echo "OK" || echo "FAIL" 

instead

Sorry but the exitcode is correctly printed. Also, this issue is actually relevant, why did we close it?

~ » bash -c "exit 11"; echo $?
