assertion vs go-tty

Ginkgo's Preferred Matcher Library.

Go-tty Simple tty utility Usage ```go tty, err := tty.Open() if err != nil { log.Fatal(err) } defer tty.Close() for { r, err := tty.ReadRune() if err != nil { log.Fatal(err) } // handle key event } ``` if you are on windows and want to display ANSI colors, use go-colorable.
