断言元素内的文本是否包含特定的部分文本

要验证任何元素中所需文本的存在，您需要使用一个

try-catch{}

text_to_be_present_in_element()

• 使用

  CSS_SELECtOR

  ：

  try:WebDriverWait(driver, 20).until(EC.text_to_be_present_in_element((By.CSS_SELECTOR, "div.ui-dialog-content.ui-widget-content#dialog>pre"), "Text is here"))print("Desired text was present")

  except TimeoutException:
  print(“Desired text was not present”)
  

• 使用

  XPATH

  ：

  try:WebDriverWait(driver, 20).until(EC.text_to_be_present_in_element((By.XPATH, "//div[@ and @id='dialog']/pre"), "Text is here"))print("Desired text was present")

  except TimeoutException:
  print(“Desired text was not present”)
  

• 注意 ：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait

  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.common.exceptions import TimeoutException
