我正在学习 Selenium 。为什么这个简单的测试失败了?
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.common.action_chains import ActionChains
import unittest
class ToolTipTest (unittest.TestCase):
def setUp(self):
self.driver = webdriver.Firefox()
self.driver.get("http://jqueryui.com/tooltip/")
self.driver.implicitly_wait(30)
self.driver.maximize_window()
def test_tool_tip(self):
driver = self.driver
frame_elm = driver.find_element_by_class_name("demo-frame")
driver.switch_to.frame(frame_elm)
age_field = driver.find_element_by_id("age")
ActionChains(self.driver).move_to_element(age_field).perform()
tool_tip_elm = WebDriverWait(self.driver, 10).until(
expected_conditions.visibility_of_element_located(
(By.CLASS_NAME, "ui-tooltip-content")))
# verify tooltip message
self.assertEqual(
"We ask for your age only for statistical purposes.",
tool_tip_elm.text)
def tearDown(self):
self.driver.close()
if __name__ == "__main__":
unittest.main(verbosity=2)
有时它会给出
AssertionError: 'We ask for your age only for statistical purposes.' != "ThemeRoller: jQuery UI's theme builder app
lication"
- We ask for your age only for statistical purposes.
+ ThemeRoller: jQuery UI's theme builder application
有时:
AssertionError: 'We ask for your age only for statistical purposes.' != "That's what this widget is"
- We ask for your age only for statistical purposes.
+ That's what this widget is
所以错误并不总是相同的。有时它会过去。看起来它选择了一个随机弹出窗口。 Here's要测试的页面。我正在使用 python 3.6 selenium 3
编辑:另外,我如何检查(在 Firefox 开发人员工具中)工具提示的 html 代码以查看类、id 等?当我选择代码时,工具提示消失,代码也消失......
最佳答案
你就快到了。带有工具提示文本的元素不正确。要断言工具提示文本,您可以使用以下优化解决方案:
代码块:
from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.common.action_chains import ActionChains import unittest class ToolTipTest (unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() self.driver.get("http://jqueryui.com/tooltip/") self.driver.implicitly_wait(30) self.driver.maximize_window() def test_tool_tip(self): driver = self.driver WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.demo-frame"))) age_field = driver.find_element_by_css_selector("input#age") ActionChains(self.driver).move_to_element(age_field).perform() tool_tip_elm = WebDriverWait(self.driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.ui-helper-hidden-accessible div:not([style])"))) self.assertEqual("We ask for your age only for statistical purposes.", tool_tip_elm.text) def tearDown(self): self.driver.quit() if __name__ == "__main__": unittest.main(verbosity=2)
控制台输出:
test_tool_tip (__main__.ToolTipTest) ... ok ---------------------------------------------------------------------- Ran 1 test in 17.618s OK
关于python - 如何通过 Selenium 和 Python 单元测试断言工具提示文本,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/54409589/
