python - 难以缩小复选框的 XPath 范围

Question

我正在以下网站上练习一些 Selenium:

www.automationpractice.com

我在下面开始了一些基本测试:

import unittest
from webdriver import Driver
from values import strings
from pageobjects.homescreen import Homescreen


class TestHomeScreen(unittest.TestCase):
    @classmethod
    def setUp(self):
        self.driver = Driver()
        self.driver.navigate(strings.base_url)

    def test_home_screen_components(self):
        home_screen = Homescreen(self.driver)
        home_screen.logo_present()

    def test_choose_dress(self):
        home_screen = Homescreen(self.driver)
        home_screen.choose_dress()

    @classmethod
    def tearDown(self):
        self.driver.instance.quit()

这些测试是从以下内容中读取的:

from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from values import strings


class Homescreen:

    def __init__(self, driver):
        self.driver = driver

    def logo_present(self):
        self.logo = WebDriverWait(self.driver.instance, 10).until(
            EC.visibility_of_element_located((
                By.ID, "header_logo")))
        assert self.logo.is_displayed()

    def choose_dress(self):
        self.dresses = WebDriverWait(self.driver.instance, 5).until(
            EC.visibility_of_element_located((
                By.XPATH, '//*[@id="block_top_menu"]/ul/li[2]/a')))
        self.dresses.click()
        self.casual_dresses = WebDriverWait(self.driver.instance, 10).until(
            EC.visibility_of_element_located((
                By.XPATH,'//input[@type="checkbox" and @id="layered_category_9"]')))

test_home_screen_components 通过良好，但 test_choose_dress 失败。我已经缩小了范围，它在最终的 XPATH 上失败了，这是一个“休闲服装”的复选框。找不到它。我已在 Chrome 中确认此 XPATH 有效:

self.casual_dresses = WebDriverWait(self.driver.instance, 10).until(
     EC.visibility_of_element_located((
         By.XPATH,'//input[@type="checkbox" and @id="layered_category_9"]')))

所以我不确定问题是什么。也许我遗漏了一些东西，因为它是嵌入的？

而且我知道我最终也需要在我的代码中添加一些 Try/Except，我才刚刚开始使用这些东西。

Answer 1

直接替换即可

EC.visibility_of_element_located

与

EC.presence_of_element_located

能够处理所需的复选框
