Testing my kong binary

[TheKushIsGood]

Once the tool is built using kong, is there a good way to test the command line options/flags/interface? I am thinking of a way to do it as I have a fairly large tool with many options/arguments/flags.

Of course. I usually test it with something like this:

parser, err := kong.New(&CLI{}, kong.Exit(func(n int) {
  if n != 0 { t.Fatalf("exited with %d exit status", n) }
}))
