# This is a file that contains a list of specs in the order you want them executed
# A good way to obtain it is by taking the output of this script and sorting them based on time taken
# so that longest tests run first. You can do it with: `sort result.txt -k 2 -r | grep -o '[^ ]*rb'`
# This script will try to follow that order, but any unlisted tests will be put at the beginning
