在Python Selenium中等待，页面对象模型不起作用

Question

我有这个登录页面输入用户名密码，然后点击登录按钮（这是我的代码）：

    def enter_username(self):
    # Click on Email field
    self.find_element(*self.locator.email_field).click()
    # Clear Email field
    self.find_element(*self.locator.email_field).clear()
    # Tape Email
    self.find_element(*self.locator.email_field).send_keys(user1_email)

def enter_password(self):
    # Click on Password field
    self.find_element(*self.locator.password_field).click()
    # Clear Password field
    self.find_element(*self.locator.password_field).clear()
    # Tape Password
    self.find_element(*self.locator.password_field).send_keys(user1_password)

def click_login(self):
    # Click on the user menu
    self.find_element(*self.locator.login_button).click()

我使用这个locators类包含ID：

class LoginPageLocators(object):

email_field = (By.XPATH,'//*[@id="sCourriel"]')
password_field = (By.XPATH,'//*[@id="sPassword"]')
login_button = (By.NAME,'loginBTN')

我使用这个基本页面：

class Page(object):
def __init__(self, driver, base_url=uat_qa_url):
    self.base_url = base_url
    self.driver = driver
    self.timeout = 30

def find_element(self, *locator):
    return self.driver.find_element(*locator)

def open(self, url):
    url = self.base_url + url
    self.driver.get(url)

def get_title(self):
    return self.driver.title

def get_url(self):
    return self.driver.current_url

def hover(self, *locator):
    element = self.find_element(*locator)
    hover = ActionChains(self.driver).move_to_element(element)
    hover.perform()

我的测试用例：

    def test_consultation_CCI_WBA_001(self):
    loginPage = LoginPage.Loginpage(self.driver)
    consultationPage = ConsultationsPage.Consultationspage(self.driver)
    homePage = HomePage.Homepage(self.driver)

    # Test case CCI_WBA_001 (Créer une consultation avec les informations nécessaires)

    # Login ass admin
    loginPage.enter_username()
    time.sleep(5)
    loginPage.enter_password()
    time.sleep(5)
    loginPage.click_login()
    time.sleep(5)

我的问题是：我怎样才能消除时间。睡眠或者如何使用wait for element present？ 谢谢

Answer 1

你有两个选择。你知道吗

1）隐式等待：当您有以下代码行时，它将确保驱动程序为元素等待指定的时间。你知道吗

driver.implicitly_wait('10')

2）显式等待：您可以使用下面的命令等待元素显式出现。你知道吗

需要导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

代码：

def enter_username(self):
    # wait for the email element (update the location strategy based on your condition)
    email = WebDriverWait(driver,30).until(EC.presence_of_element_located((By.id("id goes here"))))
    # Clear Email field
    email.clear()
    # Tape Email
    email.send_keys(user1_email)
