Question

我是Python新手，我正在尝试编写一个用于测试网站链接的小代码。我创建了一个字典如下：

header_dropdown_links = {
            'Features' : 'Features', 
            'Company' : 'Company | Values',
            'Community' : 'Community | Open Sauce',
            'Solutions' : 'Selenium Testing | Solutions',
            'Resources' : 'Resources',
            'Enterprise' : 'Enterprise',
            'Sign Up' : 'Sign Up',
            'Docs' : 'Docs',
            'Pricing' : 'Pricing',
            'Login' : 'Login'      
       }

左侧是链接名称，右侧是页面标题。

我创建了以下表达式，以便在循环中找到每个链接并将其与标题匹配。对于header_dropdown_links中的链接：

header_link = '//nav[@id ="global"]//a[contains(text(),' + link + ')]'
        driver.find_element_by_xpath(header_link).click()

现在，当我运行此代码时，我每次只点击“资源”链接，但它匹配所有标题我不清楚为什么？有人可以帮帮我吗？

我正在尝试检查字形中的链接（3行图标）。我写的代码：

# -*- coding: utf-8 -*-
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
import unittest

header_dropdown_links = {
        'Features' : 'Features', 
        'Company' : 'Company | Values',
        'Community' : 'Community | Open Sauce',
        'Solutions' : 'Selenium Testing | Solutions',
        'Resources' : 'Resources',
        'Enterprise' : 'Enterprise',
        'Sign Up' : 'Sign Up',
        'Docs' : 'Docs',
        'Pricing' : 'Pricing',
        'Login' : 'Login'      
    }

class SauceLabsHeader(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = 'https://saucelabs.com/'
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_sauce_labs_header(self):
        driver = self.driver

        for link in header_dropdown_links: 

            #opens SauceLabs Home Page
            driver.get(self.base_url)

            #clicks on Glyph for opening the drop down menu
            driver.find_element_by_class_name('hamburger').click()

            #finding link by xpath
            header_link = '//nav[@id ="global"]//a[contains(text(),' + link + ')]'
            driver.find_element_by_xpath(header_link).click()

            #verifying if the title matches
            expected_title = header_dropdown_links[link]
            try: self.assertRegexpMatches(driver.title,expected_title)
            except AssertionError as e: self.verificationErrors.append(str(e))


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

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

我得到的错误：

Answer 1

你确定这部分是正确的吗？

header_link = '//nav[@id ="global"]//a[contains(text(),link)]'

不应该 -

header_link = '//nav[@id ="global"]//a[contains(text(),"' + link + '")]'

您希望link作为包含在字符串中的字符串，还是希望每个链接中都有文字，例如Resources？

Answer 2

仍显示错误：

# on each of your nodes, start the swarm agent
#  <node_ip> doesn't have to be public (eg. 192.168.0.X),
#  as long as the swarm manager can access it.
$ swarm join --addr=<node_ip:2375> token://<cluster_id>

相同的链接在循环中打开
