      To activate modules, add the following at the end of your .zshrc:
        source #{opt_prefix}/init/zsh
      You will also need to reload your .zshrc:
        source ~/.zshrc
    EOS

    assert_match "restore", shell_output("#{bin}/envml --help")
    output = shell_output("zsh -c 'source #{prefix}/init/zsh; module' 2>&1")
    assert_match version.to_s, output
