用selenium 的 xpath定位元素，为什么没报错但却没有去点击呢？

Question

def setUp(self):
    self.url = "https://m.baidu.com/sf?top=%7B%22sfhs%22%3A1%7D&anchor=0811&pd=pl&word=%E8%87%AA%E7%94%B1%E4%BE%A0"
    options = webdriver.ChromeOptions()
    mobileEmulation = {'deviceName': 'Galaxy Note 3'}
    options.add_experimental_option('mobileEmulation', mobileEmulation)
    self.driver = webdriver.Chrome(executable_path='chromedriver.exe', chrome_options=options)
    self.driver.implicitly_wait(10)  #最多等待10秒，隐性等待对整个driver的周期都起作用，所以一次启动只要设置一次即可
    self.driver.get(self.url)
    self.assertTrue(ec.title_is(u"自由侠"))
    self.assertTrue(ec.visibility_of_element_located(u"自由侠"))

def tearDown(self):
    self.driver.quit()

def testCase1(self):
    locator = self.driver.find_element_by_xpath('//span[contains(text(), "7寸液晶仪表")]')
    locator.click()

Answer 1

没有找到这个元素所以没点击，可能该页面有多个你要找的元素
