如何进行单元测试 itertools.combinations 检查以便随机选择输入？

Question

full_name = '姓氏', '名字', 'patronymic', 'email_mobilenumber'

if wrong_input_mob: for id in full_name: selector = '#%s' % id if self.browser.find_elements_by_css_selector(selector): name = {} name[id] = self.mob_incorrect_input(selector)

def mob_incorrect_input(self, selector):
    arr = ['higjieurhgfihr', '    ', '98/7654321', '123456789']
    combo = self.browser.find_element_by_css_selector(selector).send_keys(' fjijkewrhfr ')
    for combo in itertools.combinations(arr, 3):
        return combo
