Ideas for a pre-commit hook. Welcome.

pre-commit

#!/usr/bin/env ruby

# Drop in .git/hooks
# Make executable and get back to werk.

# Stash files not to be committed
system('git stash -q --keep-index')

# check for rake
rake_available = system('bundle list | grep rake > /dev/null')
minitest_available = system('bundle list | grep minitest > /dev/null')
rspec_available = system('bundle list | grep rspec > /dev/null')

if rake_available && minitest_available
  # Run test
  puts 'Running Tests...'
  system('bundle exec rake test')
end

if rspec_available
  # Run test
  puts 'Running Tests...'
  system('bundle exec rspec spec')
end

# Unstash changes to the working tree that we had stashed
system('git stash pop -q')
