Heres an example git hook to run your Rails specs automatically upon commit/push

#!/usr/bin/env ruby

if ENV["SKIP_GLOBAL_GIT_HOOKS"].to_s == "true"
  exit 0
end


if ENV["SKIP_TESTS"].to_s != "true"
  if Dir.exists?("spec/")
    test_cmd = "bundle exec rspec spec"
  elsif Dir.exists?("test/")
    test_cmd = "bundle exec rake test"
  end

  if test_cmd
    puts "RUNNING TEST SUITE...\n"

    if system(test_cmd, out: STDOUT)
      test_passed = true
    end

    if !test_passed
      puts "\nCOMMIT FAILED!! See failing test output above."
      puts "To skip this check use `SKIP_TESTS=true`"
      exit 1
    end
  end
end

Also since git hooks are not committed to your repository you can either use one of the following techniques to save this git hook:

• If you want to share the hook with all team members working on the project, then use the .githooks technique
• If you want to have this hook available to every project you personally work on, then use the global git hooks technique as described below
  • Create a folder within your dotfiles repo for your git hooks and add your git hooks here
  • Add the following line to your .bashrc/.zshrc (recommended) or run manually, [[ -d "$HOME/path/to/your/global_git_hooks_folder" ]] && git config --global core.hooksPath "$HOME/path/to/your/global_git_hooks_folder"
  • Now every project you work on will also include the global hooks from the specified folder
