Given a list of specs, run one test together with each in the list

test_specs.sh

#!/bin/bash
#
# Run a failing spec in combination with each other spec and record which combinations cause a failure
#
# Put a list of all specs into specs.txt
# eg: $ $ find spec -name '*_spec.rb' -print > specs.txt
# Set the failingspec variable below
# Set the seed variable below
#
# Writes a log to testspec.log, which is formatted as follows:
#   ...
#   OK: ./spec/controllers/my_controller_spec.rb and ./spec/controllers/my_failing_spec.rb
#   OK: ./spec/controllers/other_controller_spec.rb and ./spec/controllers/my_failing_spec.rb
#   FAILED: ./spec/controllers/bad_controller_spec.rb and ./spec/controllers/my_failing_spec.rb
#   ...
