Question

我遇到使用Selenium Webdriver点击按钮的问题。我试过等待无济于事，但我可能没有正确地做到这一点，尽管我不熟悉这一点。我也收到有关全球驾驶员问题的错误，但同样，我没有做到这一点，并且无法找到正确的方法来解决这个问题。

错误我得到了：

ERROR: test_categorySelect (__main__.TitleTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "auto2.py", line 24, in test_categorySelect
    category = self.wait.until(EC.visibility_of_element_located((By.XPATH, "//li[]@id='menu-item-34']/a")))
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/support/wait.py", line 80, in until

以下是演示网站：

http://store.demoqa.com

我尝试点击的区域的代码在这里：

<ul class="sub-menu">
<li id="menu-item-34" class="menu-item menu-item-type-taxonomy menu-item-object-wpsc_product_category menu-item-34">
    <span class="before">&nbsp;</span>
    <a href="http://store.demoqa.com/products-page/product-category/accessories/">
        <span></span>
        Accessories
    </a>
</li>

这是我目前的代码：

import unittest
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

class TitleTest(unittest.TestCase):

def setUp(self):
    # self.driver = webdriver.Chrome()
    self.driver = webdriver.PhantomJS()
    self.wait = WebDriverWait(driver, 10)

def test_title(self):
    self.driver.get("http://store.demoqa.com")
    self.assertIn("STORE", self.driver.title)
    print "================================================================"
    print "==== Successful Title Match ===="
    print "================================================================"

def test_categorySelect(self):
    category = self.wait.until(EC.visibility_of_element_located((By.XPATH, "//li[]@id='menu-item-34']/a")))
    ActionChains(self.driver).move_to_element(category).click().perform()
    print "================================================================"
    print "==== Successful Accessories Button Clicked ===="
    print "================================================================"


    def tearDown(self):
        self.driver.quit()

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

Answer 1

问题在于等待子菜单显示超时，但在调用wait.until之前没有执行任何操作。

您需要使用ActionChains将鼠标悬停在“产品类别”上，然后点击特定类别。

def test_categorySelect(self):
    self.driver.get("http://store.demoqa.com")
    product_category = self.driver.find_element_by_css_selector("li[id='menu-item-33']")
    category = self.driver.find_element_by_css_selector("li[id='menu-item-34']")
    ActionChains(self.driver).move_to_element(product_category).click(category).perform()

Answer 2

您还有一个额外的右括号] ，请将您的定位器更改为："//li[@id='menu-item-34']/a"

Selenium Webdriver：问题单击下拉列表中的按钮<li>
