我正在尝试执行 Web 自动化测试，现在我一直在研究如何从出口和时间列表中选择随机值。有点没主意了，希望有人能帮忙，在此先感谢并祝你有美好的一天。

你好！我对您的问题有一个澄清：您是否能够找到完整的选项列表，但不知道如何随机选择一个选项，或者您是否正在寻找一种方法来自行阅读整个选项列表？
我没能找到完整的选项列表，我现在想做的只是从列表中选择随机选项。

【解决方案1】：

据我了解上面的代码，这样的事情应该有效：

from random import choice
# pass here a results from select
list_of_select_objects = ['obj1', 'obj2', 'obj3']
# creates a list of indexes
list_of_indexes = list(range(len(list_of_select_objects)))

random_index = choice(list_of_indexes)
# you get a random index
select.select_by_index(random_index)
# use it to select a random element

兄弟没用。。。
你能为这个问题提供这一行返回的类型和结构吗？ select = Select(driver.find_element(By.XPATH,"//*[@id='edit-hours']/div[1]/select"))
devbusiness.tunai.io/dashboard/my_salon_appointment# 兄弟你可以登录网站去我的沙龙下预约。单击“编辑预约时间”，您将在那里看到选项。我想从“选择网点”中选择随机值，从“自动设置时间”中选择随机时间
该行没有返回任何错误。

【解决方案2】：

您可以尝试以下代码：

driver.get("https://devbusiness.tunai.io/dashboard/my_salon_appointment")
time.sleep(1)

# click Edit Appointment Hours button
Button = driver.find_element(By.XPATH,"//*[text()=' Edit Appointment Hours ']")
Button.click()
time.sleep(1)

# click Select Outlet dropdown
element = driver.find_element(By.CSS_SELECTOR,".multiselect.col-md-4 .multiselect__tags")
driver.execute_script("arguments[0].scrollIntoView();", element)
time.sleep(1)
element.click()

outlet_options = driver.find_elements(By.XPATH,".//*[contains(@class,'multiselect col-md-4')]//span[@class='multiselect__option']")

option_to_select = random.randint(1, len(outlet_options) - 2)
print("option to select in Select outlet - ", option_to_select)

driver.find_element(By.XPATH, "(.//*[contains(@class,'multiselect col-md-4')]//span[@class='multiselect__option'])[" + str(option_to_select) + "]").click()

time.sleep(1)

time_to_select = random.randint(1, 3)
print("time to select: ", time_to_select)
select = Select(driver.find_element(By.XPATH,".//*[@name='predefinedHours']"))
select.select_by_index(time_to_select)
time.sleep(1)

driver.find_element(By.XPATH,"//*[@id='edit-hours']/div[4]/button").click()
