  def caveats
    <<~EOS
      To activate the syntax highlighting, add the following at the end of your .zshrc:
        source #{HOMEBREW_PREFIX}/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

      If you receive "highlighters directory not found" error message,
      you may need to add the following to your .zshenv:
        export ZSH_HIGHLIGHT_HIGHLIGHTERS_DIR=#{HOMEBREW_PREFIX}/share/zsh-syntax-highlighting/highlighters
    EOS
  end

  test do
    assert_match "#{version}\n",
