Serhiy suggested to write an unit test for curses.ncurses_version:

I think it is better to add tests for different modules in corresponding module test files. They are pretty trivial, for example:

    def test_new_tcl_obj(self):
        self.assertRaises(TypeError, _tkinter.Tcl_Obj)

    @requires_curses_func('panel')
    def test_new_curses_panel(self):
        w = curses.newwin(10, 10)
        panel = curses.panel.new_panel(w)
        self.assertRaises(TypeError, type(panel))
