RSpec failing seed finder

rspec_finder.sh

#!/bin/bash

# Finds the first seed that breaks the spec suite. Outputs to stdout and a file (rspec_output).

found=0
while [ $found == 0 ]
do
  rspec --order random 2>&1 | tee -a ./rspec_output
  found=$(more rspec_output | grep Failed | wc -l)
  if [ $found == 0 ]
    then
      > rspec_output # empty results if not found
  fi
done

echo "Found failing seed."

FWIW --order random is redundant and I don't think it worth to append to the output:

while bundle exec rspec --format json --output ./rspec_output; do
  echo "All good, keep trying..."
done

seed="$(cat ./rspec_output | jq '.seed')"
echo "Found failing seed: ${seed}; Running rspec bisect to nail it down..."

bundle exec rspec --bisect=verbose --order "random:${seed}"
