playwright+pytest+python怎么写循环

写循环有多种方法，这里我提供两种使用 `pytest` 和 `playwright` 的示例：

1. 使用 `pytest.mark.parametrize` 和列表循环：

import pytest
from playwright.sync_api import Playwright, Browser

@pytest.fixture(scope="module")
def browser(context: Playwright) -> Browser:
    browser = context.chromium.launch()
    page = browser.new_page()
    page.goto("https://www.baidu.com")
    yield browser
    browser.close()

@pytest.mark.parametrize(
    "keyword",
    [
        "playwright",
        "pytest",
        "python",
    ],
)
def test_search(browser: Browser, keyword: str):
    search_input = browser.page.locator("[name='wd']")
    search_button = browser.page.locator("[type='submit']")
    search_input.fill(keyword)
    search_button.click()
    assert keyword in browser.page.title()

2. 使用 `for` 循环：

from playwright.sync_api import Playwright, Browser

def test_search(browser: Browser):
    keywords = ["playwright", "pytest", "python"]
    for keyword in keywords:
        search_input = browser.page.locator("[name='wd']")
        search_button = browser.page.locator("[type='submit']")
        search_input.fill(keyword)
        search_button.click()
        assert keyword in browser.page.title()

以上两种方法都可以实现循环测试，具体选择哪种方法可以根据实际情况进行选择。
