  def caveats
    <<~EOS
      By default, iggy server configuration file is loaded from the current working directory.
      You can specify the path to your custom configuration file by setting IGGY_CONFIG_PATH
      environment variable, for example:

        export IGGY_CONFIG_PATH=configs/server.json

      Alternatively you may want to use the default server configuration like this:

        IGGY_CONFIG_PATH=#{pkgetc}/configs/server.json iggy-server
    EOS
  end

  test do
    assert_match "server #{version}", shell_output("#{bin}/iggy-server -V").strip
  end
end
