经过今天的研究发现在user-profile-name元素定位嵌套在iframe标签里修改代码之后还是有问题，获取的text为空，但是已检查Xpath路径是没有问题的

sleep(5)
framm=driver.find_element(By.XPATH,'/html/body/div[2]/div[2]/iframe')
driver.switch_to.frame(framm)
#切换ifrme
#driver.switch_to.frame('appIframe-program')
sleep(15)
if driver.find_element(By.XPATH, '//div[@class="user-profile-name"]').text == 'admin':
    print('pass')
else:
    print('fail')

while 1:
    start = time.perf_counter()
    try:
        driver.switch_to.frame('appIframe-my')
        driver.find_element(By.XPATH, '//div[@class="user-profile-name"]').click()
        print ('已定位到元素')
        end=time.perf_counter()
        break
    except:
        print ("还未定位到元素!")
        break

pycharm 运行结果
fail
还未获取到元素
