WinAppDriver & Python 错误：AttributeError：“dict”对象没有属性“click”

Question

我有一个迷你项目，需要使用 Python 在 GUI windows 应用程序上自动执行任务。

在尝试寻找解决方案时，我发现了类似于 Selenium 的 WinAppDriver。

当我尝试运行 python 示例代码时，它返回了这个错误：“AttributeError: 'dict' object has no attribute 'click'”

这里是python代码：

from appium import webdriver

class SimpleCalculatorTests(unittest.TestCase):

    @classmethod

    def setUpClass(self):
        #set up appium
        desired_caps = {}
        desired_caps["app"] = "Microsoft.WindowsCalculator_8wekyb3d8bbwe!App"
        self.driver = webdriver.Remote(
            command_executor='http://127.0.0.1:4723',
            desired_capabilities= desired_caps)

    @classmethod
    def tearDownClass(self):
        self.driver.quit()

    def getresults(self):
        displaytext = self.driver.find_element_by_accessibility_id("CalculatorResults").text
        displaytext = displaytext.strip("Display is " )
        displaytext = displaytext.rstrip(' ')
        displaytext = displaytext.lstrip(' ')
        return displaytext


    def test_initialize(self):
        self.driver.find_element_by_name("Clear").click()
        self.driver.find_element_by_name("Seven").click()
        self.assertEqual(self.getresults(),"7")
        self.driver.find_element_by_name("Clear").click()

    def test_addition(self):
        self.driver.find_element_by_name("One").click()
        self.driver.find_element_by_name("Plus").click()
        self.driver.find_element_by_name("Seven").click()
        self.driver.find_element_by_name("Equals").click()
        self.assertEqual(self.getresults(),"8")

    def test_combination(self):
        self.driver.find_element_by_name("Seven").click()
        self.driver.find_element_by_name("Multiply by").click()
        self.driver.find_element_by_name("Nine").click()
        self.driver.find_element_by_name("Plus").click()
        self.driver.find_element_by_name("One").click()
        self.driver.find_element_by_name("Equals").click()
        self.driver.find_element_by_name("Divide by").click()
        self.driver.find_element_by_name("Eight").click()
        self.driver.find_element_by_name("Equals").click()
        self.assertEqual(self.getresults(),"8")

    def test_division(self):
        self.driver.find_element_by_name("Eight").click()
        self.driver.find_element_by_name("Eight").click()
        self.driver.find_element_by_name("Divide by").click()
        self.driver.find_element_by_name("One").click()
        self.driver.find_element_by_name("One").click()
        self.driver.find_element_by_name("Equals").click()
        self.assertEqual(self.getresults(),"8")

    def test_multiplication(self):
        self.driver.find_element_by_name("Nine").click()
        self.driver.find_element_by_name("Multiply by").click()
        self.driver.find_element_by_name("Nine").click()
        self.driver.find_element_by_name("Equals").click()
        self.assertEqual(self.getresults(),"81") 

    def test_subtraction(self):
        self.driver.find_element_by_name("Nine").click()
        self.driver.find_element_by_name("Minus").click()
        self.driver.find_element_by_name("One").click()
        self.driver.find_element_by_name("Equals").click()
        self.assertEqual(self.getresults(),"8")

if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(SimpleCalculatorTests)
    unittest.TextTestRunner(verbosity=2).run(suite)

这是python响应：

Answer 1

我找到了解决方案，即通过运行将 Selenium 恢复为 3.141.0：

pip install selenium==3.141.0

资源

Answer 2

为了详细说明 Anas H 的答案，驱动程序正在返回一个字典，但它应该返回一个 WebElement。 简而言之，WinAppDriver 目前似乎没有完全支持 Selenium 4，但它确实支持 Selenium 3.14。 使用 Anas H 提供的 pip 命令

pip install selenium==3.14

或者对于 PyCharm，在 Python Packages 下，您可以输入 Selenium 并删除当前的 selenium 包。 研究 Selenium 而不是 Selenium 4，选择您想要的 Selenium 3.1 版本，我再次使用 3.14。

如果出于某种原因您选择坚持使用 Selenium 4，那么您在提供的示例中可能遇到的其他问题将是“find_element()”函数。 您需要从 selenium.webdriver.common.by 导入“By”才能找到任何特定元素。

# Selenium 3
self.driver.find_element_by_name("Nine").click()

# Selenium 4
from selenium.webdriver.common.by import By
self.driver.find_element(By.NAME, "Nine")
