Question

我对python比较陌生。

我正在尝试使用硒网格上的pytest在不同的浏览器上以单个测试的形式在一个文件中运行所有测试。

我正在尝试两种方法，能够使用url启动5个不同的浏览器，但是测试没有继续进行，并且两种方法都出现错误。

方法1：

import logging 
import ast
import unittest
import sys
import pytest
import traceback
import allure
import softest
from time import sleep

logging.basicConfig(level = logging.INFO)

    "version": "83.0",
    "enableVNC": True,
    "enableVideo": False
}

ch2_capabilities = {

    "version": "81.0",
    "enableVNC": True,
    "enableVideo": False
}

ch3_capabilities = {
    "browserName": "chrome",
    "version": "80.0",
    "enableVNC": True,

}

ch4_capabilities = {

    "version": "79.0",
    "enableVNC": True,
    "enableVideo": False
}

ch5_capabilities = {

    "version": "78.0",
    "enableVNC": True,
    "enableVideo": False
}

ch3_driver = webdriver.Remote(

    desired_capabilities=ch4_capabilities)

ch5_driver = webdriver.Remote(

@pytest.mark.abc_test()
@pytest.mark.parametrize("driver_node", [ch1_driver,ch2_driver,ch3_driver,ch4_driver,ch5_driver])
class test_abc_Chrome(softest.TestCase):
    
    @classmethod
    def setUpClass(self):
        self.driver=driver_node
        self.driver.maximize_window()
        self.driver.get('https://example.com')
        sleep(7)

    @allure.feature("Verify_XYZ")
    @allure.description("verify xyz")
    def test_000_Verify_XYZ(self):
        logging.info("verify xyz")
        with allure.step("verify xyz"):
            sleep(1)
            element = self.driver.find_element_by_xpath("//*[text()='expectedText']")
            assert element.text == 'expectedText'

方法1的错误

 @classmethod
    def setUpClass(self):
>       self.driver=driver_node
E    NameError: name 'driver_node' is not defined

    for driver_node in driver_nodes:
        driver = driver_node
        request.instance.driver = driver
        driver.maximize_window()
        driver.get("https://example.com")
        sleep(10)
        yield driver


@pytest.mark.usefixtures("setup")

            element = self.driver.find_element_by_xpath("//*[text()='expectedText']")
            assert element.text == 'expectedText'

方法2的错误

 for driver_node in driver_nodes:

我也在尝试通过改变这两种方法中的一些方法，但是还没有运气。

如果有人可以帮助我解决该问题，那将是一个很大的帮助。

Answer 1

您尚未初始化WebDriver和 WebBrowser 实例。

解决方案

在使用from webdriver_manager.chrome import ChromeDriverManager时，您需要在def setUpClass(self):内添加以下行：

driver = webdriver.Chrome(ChromeDriverManager().install())

有效地，您的代码块将是：

@classmethod
def setUpClass(self):
    driver_node = webdriver.Chrome(ChromeDriverManager().install())
    self.driver=driver_node
    self.driver.maximize_window()
    self.driver.get('https://example.com')

尝试使用pytest for硒网格运行硒测试时出错
