Web自动化测试之playwright:pages、popup、dialog和frame处理
本文介绍如何使用playwright来处理新页面、frame以及对话框。
新页面窗口
获取浏览器上下文产生的新页面,也就是通过 target="_blank"
链接打开的新窗口。
with context.expect_page() as new_page_info:
page.click('a[target="_blank"]')
new_page = new_page_info.value
new_page.wait_for_load_state()
点击【立即注册】会打开一个新的页面:

下面代码实现打开百度,点击登录,进入注册界面
from time import sleep
from playwright.sync_api import sync_playwright
class TestDemo():
def setup(self):
playwright = sync_playwright().start()
self.browser = playwright.chromium.launch(headless=False)
self.context = self.browser.new_context()
self.page = self.context.new_page()
def teardown(self):
self.browser.close()
def test_click(self):
self.page.goto("http://www.baidu.com")
self.page.click('id=s-top-loginbtn')
with self.context.expect_page() as new_page_info:
self.page.click('"立即注册"') # Opens a new tab
register_page = new_page_info.value
register_page.wait_for_load_state()
print(register_page.title())
# 注册用户名密码
register_page.fill("id=TANGRAM__PSP_4__userName", "username")
register_page.fill("id=TANGRAM__PSP_4__phone", "12345678")
register_page.close()
sleep(2)
# 登录用户名密码
self.page.fill("id=TANGRAM__PSP_11__userName", "username")
self.page.fill("id=TANGRAM__PSP_11__password", "pwd")
sleep(2)
playwright不像selenium那样在有头模式下可以切换窗口,它默认是无头模式的,直接对对应的页面对象进行操作就可以了。
selenium窗口切换参考Selenium switch_to方法
弹框处理
页面中的弹框(popup)是很常见的,处理方法和打开新页面类似:
with page.expect_popup() as popup_info:
page.click("#open")
popup = popup_info.value
popup.wait_for_load_state()
print(popup.title())
对话框处理
常见对话框包括alert(), confirm(), prompt()等,默认情况下,Playwright会取消对话框,可以通过在触发对话框之前注册一个对话框句柄:
page.on("dialog", lambda dialog: dialog.accept())
page.click("button")

def test_dialog(self):
self.page.goto("https://sahitest.com/demo/confirmTest.htm")
self.page.click('[name="b1"]') # 默认取消对话框
# 接受对话框
self.page.on("dialog", lambda dialog: dialog.accept())
self.page.click('[name="b1"]')
sleep(5)
frame切换
获取frame方法如下:
# 通过frame的name属性
frame = page.frame('frame-login')
# 通过frame的URL
frame = page.frame(url=r'.*domain.*')
# 通过选择器selector
frame_element_handle = page.query_selector('.frame-class')
frame = frame_element_handle.content_frame()
