playwright自动化测试应用-Day1-【安装使用】

 1. 安装
# pip install playwright                  ## Playwright要求Python 3.7及以上。python --version 或 python3 --version查看
# playwright install
# python -m pip install --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple  ## 建议更新pip版本到25

 2. 创建测试脚本
from playwright.sync_api import sync_playwright

def test_example():
    with sync_playwright() as p:
        browser = p.chromium.launch()
        page=browser.new_page()
        page.goto("https://example")
        # assert "" in page.title()
        browser.close()

3. 元素定位
    page.click("#submit")                   # 点击按钮
    page.fill("#username","myname")         # 输入文本
    page.check("#agree")                    # 勾选复选框
    page.select_option("#gender","M")       # 下拉框
    page.wait_for_selector("#result")       # 等待某个元素出现

 4. 截图+等待+断言
    page.screenshot(path="sreenshot.png")                # 截图
    assert page.inner_text("h1") == "example Domain"     # 文本断言
    page.wait_for_timeout(1000)                          # 等待1000ms，即1s

5. 运行脚本
    # pytest test_example.py

6. 查看报告
    # pip install pytest-playwright -i https://pypi.tuna.tsinghua.edu.cn/simple  使用国内清华源
    # pip install pytest-html -i https://pypi.tuna.tsinghua.edu.cn/simple
    # pytest --browser chromium   
    # pytest --html=report.html

 7. 使用codegen自动录制脚本（推荐）

    # playwright codegen https:example.com
