Powerful Command-Line Applications in Go: ListAction example missing args (page 241)

[onyx-and-iris]

Hi, in the table driven tests on page 241 the ListAction test requires args: hosts field but it’s missing.

Suggested fix:

		{
			name:        "ListAction",
			args:       hosts,
			expectedOut: "host1\nhost2\nhost3\n",
			initList:    true,
			actionFn:    listAction,
		},
