ScriptedTmux

Description#

server, err := tmux.NewServer(tmux.ServerOptions{
	Binary: tmuxtest.ScriptedTmux(t,
		tmuxtest.ScriptedCommand{Contains: []string{"-V"}, Stdout: "tmux 3.7\n"},
		tmuxtest.ScriptedCommand{
			Contains: []string{"kill-pane"},
			Stderr:   "can't find pane: %7\n",
			ExitCode: 1,
		},
	),
})

The executable is removed with the test. It answers commands only: opening a control connection or a notification stream speaks tmux's control protocol, which a script cannot, so code that opens one needs NewServer and a real tmux.

The private version probe reports no daemon unless an entry explicitly matches its complete format argument. An entry that does so answers with the record in Stdout; the script reports it the way tmux does, as the refusal of the probe's random command word on stderr. Ordinary commands then use the executable version supplied by the script's -V answer.
