pytest-playwright执行测试报错：fixture 'page'未找到，求解决方案

问题重现 #

编写的Playwright测试代码如下：

import re
from playwright.sync_api import Page, expect


def test_pp(page: Page):
    page.goto("https://playwright.dev/")
    # Expect a title "to contain" a substring.
    expect(page).to_have_title(re.compile("Playwright"))
    # create a locator
    get_started = page.locator("text=Get Started")
    # Expect an attribute "to be strictly equal" to the value.
    expect(get_started).to_have_attribute("href", "/docs/intro")
    # Click the get started link.
    get_started.click()
    # Expects the URL to contain intro.
    expect(page).to_have_url(re.compile(".*intro"))

执行pytest时触发错误：

file D:\play_wright\test\test_sample.py, line 5
  def test_pp(page: Page):
E       fixture 'page' not found
>       available fixtures: cache, capfd, capfdbinary, caplog, capsys, capsysbinary, doctest_namespace, monkeypatch, pytestconfig, record_property, record_testsuite_property, record_xml_attribute, recwarn, tmp_path, tmp_path_factory, tmpdir, tmpdir_factory
>       use 'pytest --fixtures [testpath]' for help on them.

D:\play_wright\test\test_sample.py:5

已完成排查：安装pytest-playwright 0.3.0、Playwright 1.27.1，尝试过pytest 6.2.1及7.x版本，重启Windows电脑，问题仍存在。

解决方案 #

• 确认pytest-playwright插件已被加载
  运行pytest --trace-config，在输出中查找pytest_playwright相关条目。若未找到，说明插件未被pytest识别，需检查安装环境。

• 重新在正确环境中安装依赖
  若使用虚拟环境，先激活环境，再执行重装命令：

  pip uninstall pytest-playwright playwright -y
  pip install pytest-playwright
  playwright install
  

• 强制加载插件运行测试
  直接通过命令指定加载pytest-playwright插件：

  pytest -p pytest_playwright
  

• 检查pytest配置文件是否禁用插件
  查看项目中的pytest.ini、tox.ini或setup.cfg，确认无addopts = -p no:pytest_playwright这类禁用插件的配置，如有则删除。

• 验证测试文件/函数命名规范
  确保测试文件以test_开头、测试函数以test_开头（当前代码已符合要求，此条为通用检查项）。
