[英]Except block always being thrown even after going through the try block and rest of the program?
[英]Selenium NoSuchElement exception is still being thrown in a try block
我正在尝试使用 try 和 except 来确保测试脚本即使在抛出异常时也能继续运行,但是我已经被问题困住了几天。 这就是问题所在,即使在 try 块中仍然会抛出“NoSuchElementException”,代码和屏幕截图附在下面。
从 selenium.common.exceptions 导入 NoSuchElementException
try:
invalid = self.driver.find_element_by_css_selector("input[value='Maintain Agency']")
except NoSuchElementException:
print("Error detected")
else:
print("Nothing went wrong")

我建议您查看此页面: https://www.toolsqa.com/selenium-webdriver/page-factory-in-selenium/
这很可能是因为在搜索元素时页面未正确加载。 您可能需要显式使用等待语句。
您可以尝试使用这样的等待:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()
driver.get(WEBSITE_URL)
element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.CSS_SELECTOR, "input[value='Maintain Agency']"))
)
