Question

我使用Python和Selenium来自动化测试用例。问题是当我到达test_press_add_to_cart时Webdriver没有看到xpath的元素：

//*[@id="fybAddCartEvent"]

可能是什么问题？

例外是：

＆＃34; TimeoutException：Message＆＃34;

元素的HTML是：

<a href="#" class="button" data-product_id="18542" data-wp_nonce="7c3d595f98" id="fybAddCartEvent">
Add to cart</a>

脚本：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.webdriver import WebDriver
from selenium.webdriver.common.action_chains import ActionChains
from HTMLTestRunner import HTMLTestRunner

class Fotball_add_to_cart(unittest.TestCase):
    @classmethod
def setUpClass(inst):
    inst.driver = webdriver.Chrome('C:/chromedriver/chromedriver.exe')
    driver = inst.driver
    driver.get("http://ak:akpass@uat.athleticknit.com/football/")
    inst.driver.maximize_window()
    time.sleep(5)

    #click on "View All Fotball Products"
def test_click_on_view_all_fotball_products(self):
    viewProductsXpath = "a.woocommerce-nested-category-layout-see-more"
    self.viewProductsElement = self.driver.find_element_by_css_selector(viewProductsXpath)
    self.viewProductsElement.click()                                                      
    time.sleep(7)
    #select a product

def test_select_a_product_and_view_details(self):
    #select product
    tshirtXpath = "//a[@href=\"http://uat.athleticknit.com/product/f810/F810-000/\"]"
    self.tshirtElement = self.driver.find_element_by_xpath(tshirtXpath)
    self.tshirtElement.click()
    time.sleep(60)

def test_press_add_to_cart(self):
    #press add to cart
    driver = self.driver
    addToCartXpath = '//*[@id="fybAddCartEvent"]'
    self.addToCartElement =WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_xpath(addToCartXpath))
    self.addToCartElement.click()
    time.sleep(5)
@classmethod    
def tearDownClass(inst):
    inst.driver.stop_client()
    inst.driver.close()
    inst.driver.quit()

实际上你在这里使用了Explicit wait

tables = ls(envir=.GlobalEnv)[sapply(ls(envir=.GlobalEnv), 

for (i in 1:length(tables)){
df=read.table(tables[[i]], sep="\t", header=T); rownames(df) = df[,1]}
}

所以它等待你的情况直到20秒，如果条件不满意则显示tables = ls(envir=.GlobalEnv)[sapply(ls(envir=.GlobalEnv), for(i in 1:length(tables)){ tables[[i]] <- tables[[i]][,-1] rownames(tables[[i]]) <- tables[[i]][,1]} }。

如果您要求等待“添加到购物车”＆＃39;然后尝试以下方式 -

self.addToCartElement =WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_xpath(addToCartXpath))

注意： - 如果你有元素id，那么请按ID而不是xpath

找到元素

TimeoutException

Python Selenium webdriver不能TimeoutException：等待元素时的消息
