def it_prints_location_by_default(show, location):
        cli.main(['show'])

        expect(show.mock_calls) == [call(location, color='path')]

def it_launches_the_config(launch, config):
        cli.main(['edit'])

        expect(launch.mock_calls) == [call(config), call().__bool__()]

def it_exits_when_no_config_found(tmpdir):
        tmpdir.chdir()

        with expect.raises(SystemExit):
            cli.main(['edit'])

def it_exits_when_no_config_found(tmpdir):

def it_can_print_a_depenendcy_path(show, location):
