Python Selenium Test Suite單個Webdriver實例？

Question

我有一些真正的問題試圖找出如何讓這個工作，我相信這里有一些專家可以為我解決，請:)

所以我在python中有很多測試用例，它們都是相互依賴的，但是是個別的腳本，我想把它們組合起來並按順序運行它們，在一個webdriver實例中，因為它們都會繼續，但我可以'似乎弄清楚該怎么做..

我創建了一個測試套件 -

import unittest

from Searchfieldreturnscorrectvalue import SearchFieldReturnsCorrectValue

from Navigatetostreetlightprecontentpage import Navigatetostreetlightprecontentpage


class TestSuite(unittest.TestSuite):

  def suite():
    suite = unittest.TestSuite()
suite.addTest(Searchfieldreturnscorrectvalue('test_searchfieldreturnscorrectvalue'))
suite.addTest(Navigatetostreetlightprecontentpage('test_navigatetostreetlightprecontentpage'))
return suite

if __name__ == "__main__":
  unittest.main()

這運行測試，但第二個失敗，因為它試圖在第二個firefox實例中運行它。

Searchfieldreturnscorrectvalue.py

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select

class SearchFieldReturnsCorrectValue(unittest.TestCase):

    self.driver = webdriver.Firefox()
    self.driver.implicitly_wait(30)
    self.base_url = "https://www.XXXXX.com/"
    self.verificationErrors = []
    self.accept_next_alert = True

def test_search_field_returns_correct_value(self):
    driver = self.driver
    driver.get(self.base_url + "/")
    driver.find_element_by_id("edit-search-block-form--2").click()
    driver.find_element_by_id("edit-query").clear()
    driver.find_element_by_id("edit-query").send_keys("street light")
    driver.find_element_by_id("edit-query").send_keys(Keys.ENTER)
    for i in range(60):
        try:
            if self.is_element_present(By.LINK_TEXT, "Street lighting"): break
        except: pass
        time.sleep(1)
    else: self.fail("time out")
    try: self.assertEqual("Street lighting", driver.find_element_by_link_text("Street lighting").text)
    except AssertionError as e: self.verificationErrors.append(str(e))

            alert.accept()
        else:
            alert.dismiss()
        return alert_text
    finally: self.accept_next_alert = True

def tearDown(self):
    self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
unittest.main()

    except AssertionError as e: self.verificationErrors.append(str(e))
    try: self.assertEqual("Report a faulty street light | Cheshire East", driver.title)
    except AssertionError as e: self.verificationErrors.append(str(e))

def is_element_present(self, how, what):
    try: self.driver.find_element(by=how, value=what)
    except NoSuchElementException as e: return False
    return True

def is_alert_present(self):
    try: self.driver.switch_to_alert()
    except NoAlertPresentException as e: return False
    return True

def close_alert_and_get_its_text(self):
    try:
        alert = self.driver.switch_to_alert()
        alert_text = alert.text
        if self.accept_next_alert:
            alert.accept()
        else:
            alert.dismiss()
        return alert_text
    finally: self.accept_next_alert = True

def tearDown(self):
    self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
unittest.main()

我不知道測試套件是否是正確的方法，或者只是將所有測試都放到一個文件中，但我仍然希望“類/測試”單獨報告通過/失敗，此刻我無法讓它工作，我認為這與setUp（self）需要被移動到setUpModule並共享？ 但我無法解決，如果有人能指出我正確的方向，我將非常感激。

謝謝

這似乎現在正在運行這兩個類，但第二個類永遠不能找到任何元素，但第一個類中的同一行完美地工作。

Answer 1

我不確定我是否理解，但是要使用單個驅動程序實例，您可以使用setupClass類方法創建驅動程序：

class MyTestClass(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Firefox()

    @classmethod
    def tearDownClass(cls):
        cls.driver.close()
        cls.driver.quit()

    def setUp(self):
         ....

它仍將為每個新測試類重新創建驅動程序，但它不會為每個測試重新創建一個（如setUp所做的那樣）。

我個人將所有測試類繼承自SeleniumTest類，如下所示：

class SeleniumTest(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Firefox()

    @classmethod
    def tearDownClass(cls):
        cls.driver.close()
        cls.driver.quit()

class MyTestClass(SeleniumTest):
    def setUp(self):
         ....

進口單位測試

來自selenium import webdriver的時間導入睡眠類SeleniumTest（unittest.TestCase）：

global driver

@classmethod
def setUpClass(cls):
    #getting a common webdriver instance for all your tests for this module
    cls.driver = webdriver.Chrome("/Users/sibasish/PycharmProjects/CommonDriverInstance/chromedriver")
    cls.driver.get("https://www.google.com")

@classmethod
def tearDownClass(cls):
    cls.driver.close()
    cls.driver.quit()

class MyTestClass（SeleniumTest）：def setUp（self）：pass

def test_sample1(self):
    print("hello1")
    self.driver.get("https://www.google.com/")
    sleep(4)

def test_sample2(self):
    print("hello2")
    self.driver.get("https://www.facebook.com/")
    sleep(4)
