web自动化工具-playwright
一、playwright安装：
pip install playwright
playwright install
二、脚本录制：
在窗口输入playwright codegen命令后，会自动打开一个浏览器窗口和录屏工具
在浏览器中输入要测试的网址，即可开始进行录制
点击copy图标，复制代码即可使用已经录制的代码
录制一个打开百度网站，搜索playwright的demo
from playwright.sync_api import Playwright, sync_playwright, expect
def run(playwright: Playwright) -> None:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
# Open new page
page = context.new_page()
# Go to https://www.baidu.com/
page.goto("https://www.baidu.com/")
# Click input[name="wd"]
page.locator("input[name=\"wd\"]").click()
# Fill input[name="wd"]
page.locator("input[name=\"wd\"]").fill("playwright")
# Click text=百度一下
page.locator("text=百度一下").click()
context.close()
browser.close()
with sync_playwright() as playwright:
run(playwright)
将录制的这段代码复制到pycharm中运行
三、常用的元素操作：
1.处理iFrame、文件上传 （ 先定位iframe,然后通过set_input_files上传图片）
# 进入iframe 上传图片
self.page.frame_locator('//*[@id="layui-layer-iframe1"]').locator('//*[@id="filePicker"]/div[2]/input') \
.set_input_files(r'D:\playwright.png')
self.page.wait_for_timeout(3000)
# 图片上传完成后 确认上传按钮还在iframe中 则需要再次定位iframe
self.page.frame_locator('//*[@id="layui-layer-iframe1"]').locator(
'//*[@id="uploader"]/div[1]/div[3]/div[3]').click()
self.page.click('//div[@class="save_s"]/input')
2.处理下拉列表框
# 处理下拉框--select_option //*[@id="province"]--省份的元素定位 28240--省份对应的value值
self.page.select_option('//*[@id="province"]', '28240')
self.page.select_option('//*[@id="city"]', '28558')
self.page.select_option('//*[@id="district"]', '28560')
self.page.fill('//input[@name="address"]', '180号')
self.page.click('//*[@id="address_submit"]')
3.根据条件定位元素
# 根据收货人名称来删除地址 收货人名称test1
self.page.click('//span[text()="test1"]/../..//a[text()="删除"]')
4.处理获取元素文本内容
# 搜索商品用例（处理获取元素文本内容）
def test_searchGoods(self):
self.page.fill('//*[@id="q"]', '手机')
self.page.click('//*[@id="sourch_form"]/a')
# 点击搜索后必须要加等待，否则无法定位出所有的商品的元素
self.page.wait_for_timeout(3000)
goods = self.page.query_selector_all('//div[@class="shop-list-splb p"]//div[@class="shop_name2"]/a')
for shop in goods:
print(shop.text_content())
5.鼠标悬停
self.page.hover('text=我的购物车')
四.使用数据驱动实现用例参数化
1.使用@pytest.mark.parametrize装饰器
2.使用yaml配置文件
# 数据驱动 方式1：
@pytest.mark.parametrize('username,password,verify', [
('13800138006', '123456', '123456'),
('13800138007', '123456', '123456')
])
def test_login(self, username, password, verify):
self.context = self.browser.new_context(no_viewport=True)
self.page = self.context.new_page()
self.page.goto("http://testingedu.com.cn:8000/Home/user/login.html")
# 登录
self.page.fill('//*[@id="username"]', username)
self.page.fill('//*[@id="password"]', password)
self.page.fill('//*[@id="verify_code"]', verify)
self.page.click('//a[@class="J-login-submit"]')
self.page.wait_for_timeout(3000)
# 数据驱动 方式2： 使用yaml文件
with open(r'D:\work\pythonCode\playwright\userData.yaml', encoding='utf-8') as f:
userData = yaml.load(f.read(), Loader=yaml.FullLoader)
print(userData)
@pytest.mark.parametrize('username,password,verify', userData)
def test_login(self, username, password, verify):
self.context = self.browser.new_context(no_viewport=True)
self.page = self.context.new_page()
self.page.goto("http://testingedu.com.cn:8000/Home/user/login.html")
# 登录
self.page.fill('//*[@id="username"]', username)
self.page.fill('//*[@id="password"]', password)
self.page.fill('//*[@id="verify_code"]', verify)
self.page.click('//a[@class="J-login-submit"]')
self.page.wait_for_timeout(3000)
userData.yaml
- ['13800138006','123456','123456'] - ['13800138006','123457','123456']
五.框架优化：pytest+playwright+allure+yaml
import os
import shutil
import allure
import pytest
import yaml
from playwright.sync_api import sync_playwright
@allure.feature('playwright测试报告')
class TestDemo3:
playwright = None
browser = None
context = None
page = None
def setup_class(self):
self.playwright = sync_playwright().start()
# 设置浏览器窗口最大化
self.browser = self.playwright.chromium.launch(headless=False, args=["--start-maximized"])
self.context = self.browser.new_context(no_viewport=True)
self.page = self.context.new_page()
def teardown_class(self):
self.browser.close()
self.playwright.stop()
# 读取yaml文件
# f = open(r'D:\work\pythonCode\playwright\testCases.yaml', encoding='utf-8') 在工程目录下直接写.\testCases.yaml就可以
f = open(r'.\testCases.yaml', encoding='utf-8')
case_dict = yaml.safe_load(f)
print(case_dict)
def run_step(self, func, value):
func(*value)
def run_case(self, testCases):
allure.title(testCases['title'])
allure.description(testCases['description'])
cases = testCases['cases']
try:
for case in cases:
func = self.page.__getattribute__(case['method'])
print('case.values()----')
print(case.values())
value = list(case.values())
print('value------')
print(value)
with allure.step(case['name']):
self.run_step(func, value[2:])
except Exception:
allure.attach(self.page.screenshot(), '用例报错图', allure.attachment_type.PNG)
pytest.fail('用例执行失败')
self.page.wait_for_timeout(1000)
allure.attach(self.page.screenshot(), '用例执行图', allure.attachment_type.PNG)
@allure.story('登录测试用例')
@pytest.mark.parametrize('testCases', case_dict['loginPage'])
def test_login(self, testCases):
self.run_case(testCases)
print('testCases------------------')
print(testCases)
self.page.wait_for_timeout(3000)
if __name__ == '__main__':
# 使用shutil删除文件夹
shutil.rmtree('./temp')
shutil.rmtree('./report')
# 使用 os.system 删除文件夹 windows:rd /s/q mac:rm -rf
# os.system('rd /s/q temp')
# os.system('rd /s/q report')
pytest.main(['-s', 'demo3.py', '--alluredir', './temp'])
os.system('allure generate ./temp -o ./report --clean')
