Bot Style Tests · SeleniumHQ/selenium Wiki · GitHub
尽管 Page Objects 在你的测试中减少重复的方式是非常有用的,这并不总是一个团队愿意遵循的模式,另一种方法是遵循更command-like
的测试风格。
一个bot
是基于Selenium APIs 面向操作的抽象。这意味着如果你发现命令对你的应用程序没有做正确的事情,改变他们很容易。
# bst.py
from selenium.webdriver.remote.webdriver import WebDriver
class ActionBot:
def __init__(self, driver: WebDriver) -> None:
self.driver = driver
def click(self, *locator):
self.driver.find_element(*locator).click()
def submit(self, *locator):
self.driver.find_element(*locator).submit()
def type(self, *locator, text):
elem = self.driver.find_element(*locator)
elem.clear()
elem.send_keys(text)
# test_bst.py
from selenium.webdriver.common.by import By
from bst import ActionBot
def test_bst(browser):
browser.get("http://www.baidu.com")
action_bot = ActionBot(browser)
action_bot.type(*(By.ID, "kw"), text="bot style tests")
action_bot.click(*(By.ID, "kw"))
time.sleep(5)
*(By.ID, "kw")
- 这种写法不太常见,我单纯是为遵循文档上的写法。
page objects 相信大家非常熟悉了,为了保持讨论的完整性,我还是给出例子。
from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.common.by import By
class Page:
def __init__(self, driver: WebDriver) -> None:
self.driver = driver
@property
def search_input(self):
return self.driver.find_element(By.ID, "kw")
@property
def search_button(self):
return self.driver.find_element(By.ID, "su")
from po import Page
def test_po(browser):
browser.get("http://www.baidu.com")
page = Page(browser)
page.search_input.send_keys("bot style tests")
page.search_button.click()
Bot Page
是什么鬼?其实我们可以把上面的两种设计模式整合一下。在Page层既包含元素又包含动作。Bot Page
是随便取的。
from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.common.by import By
class BotPage:
def __init__(self, driver: WebDriver) -> None:
self.driver = driver
def type_search_input(self, text):
self.driver.find_element(By.ID, "kw").send_keys(text)
def click_search_button(self):
self.driver.find_element(By.ID, "su").click()
from po import BotPage
def test_bst_po(browser):
browser.get("http://www.baidu.com")
page = BotPage(browser)
page.type_search_input("bot style tests")
page.click_search_button()
clear()
、send_keys()
、submit()
都是可以的。三种模式并非相互对立,可以混合使用。比如,第一种和第三种混用。
from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.common.by import By
class ActionBot:
"""bot style"""
def __init__(self, driver: WebDriver) -> None:
self.driver = driver
def click(self, *locator):
self.driver.find_element(*locator).click()
def submit(self, *locator):
self.driver.find_element(*locator).submit()
def type(self, *locator, text):
elem = self.driver.find_element(*locator)
elem.clear()
elem.send_keys(text)
class BotPage(ActionBot):
""" bot Page """
def type_search_input(self, text):
self.type(*(By.ID, "kw"), text=text)
def click_search_button(self):
self.click(By.ID, "su")
bot Page
去继承 Action bot
,bot page 写起来就简单一些了。当然,最简单的仍然是 poium。
GitHub - SeldomQA/poium: Page Objects design pattern test library, support selenium、appium、playwright, etc
from poium import Page, Element, CSSElement
class PoiumPage(Page):
search_input = Element(name='wd')
search_button = Element(id_='su')
class CssPage(Page):
search_input = CSSElement('#kw')
search_button = CSSElement('#su')
