playwright中pytest插件使用

playwright中pytest插件的使用可以通过以下步骤进行：

1. 首先，确保已经安装了playwright和pytest插件。可以使用以下命令进行安装：

pip install playwright pytest-playwright

2. 在测试文件中导入所需的模块和类。例如，导入`pytest`和`playwright`：

import pytest
from playwright.sync_api import Playwright, sync_playwright

3. 创建一个`conftest.py`文件，该文件将包含playwright的配置和夹具。在`conftest.py`中，可以定义一个夹具函数来初始化playwright并返回一个playwright实例。例如：

@pytest.fixture(scope="session")
def playwright() -> Playwright:
    with sync_playwright() as playwright:
        yield playwright

4. 在测试文件中使用playwright夹具。可以在测试函数中使用`playwright`夹具来创建浏览器实例并执行相关操作。例如：

def test_example(playwright):
    browser = playwright.chromium.launch()
    page = browser.new_page()
    page.goto("https://www.example.com")
    # 执行其他操作
    browser.close()

5. 运行pytest命令来执行测试。例如：

pytest

这样，你就可以使用playwright和pytest插件进行自动化测试了。
