如何通过Selenium和Python UnitTest断言工具提示文本

webdriverwait python-unittest assert selenium python

我在学硒。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

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。有时候会过去。看起来它选择了一个随机弹出窗口。 Here's 要测试的页面。我使用的是python 3.6 Selenium 3

编辑:我如何检查(在火狐开发工具中)工具提示的HTML代码,以查看类、ID等?当我选择代码时,工具提示会显示,代码也会显示…

你就快到了。元素 工具提示文本 不是正确的。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

添加一些(其他动态)行前等待

tool_tip_elm = ...

因为您的代码会一直等到元素可见,但弹出文本随后会更改。因此,您的测试通常比网页更改更快。

工作版本(但带有静态等待):

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
import time

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()
        time.sleep(3)
        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__":
