编写测试用例
import pytest
from playwright.sync_api import Page
def test_baidu_com(page: Page):
page.goto("https://www.baidu.com")
# xpath定位输入框，输入文本内容
page.fill('//*[@id="kw"]', "秦时明月")
# css点位点击“百度一下”按钮
page.click('#su')
# 打印title名称
print(page.title)
if __name__ == '__main__':
pytest.main(["-v", "test_baidu_example.py"])
名词解释：
test_baidu_com(page: Page):自动完成配置类型 ( page是pytest_playwright插件提供的一个夹函数，page指定到类型为Page，Page是playwright库提供的一个类，page指定类型为Page就可以调用Page类中的一些列方法 )
命令行输入命令执行：

命令行常用基础命令：
# 运行测试
pytest
# 开启页面运行
pytest --headed
# 指定浏览器运行
pytest --browser firefox
# 开启页面运行并指定浏览器运行
pytest --headed --browser firefox
# 指定两个浏览器运行，优先运行火狐再运行谷歌
pytest --browser firefox --browser chromium
# 使用浏览器频道，支持谷歌浏览器(我的电脑其他浏览器是报错的)
pytest --browser-channel chromium
# 用慢动作运行测试
pytest --slowmo 100
# 指定谷歌浏览器，开启记录每次测试的轨迹(生成一个.zip包，存放在test-results文件夹中)
pytest --browser chromium --tracing on（on:开；off:关）
# 指定谷歌浏览器，开启每次测试录制视频(生成一个.webm包，存放在test-results文件夹中)
pytest --browser chromium --video on（on:开；off:关）
# 指定谷歌浏览器，开启每次测试后是否自动截屏(生成一个.png图片，存放在test-results文件夹中)
pytest --browser chromium --screenshot on
通过浏览器跳过测试:
import pytest
from playwright.sync_api import Page
@pytest.mark.skip_browser("firefox")
def test_baidu_com(page: Page):
page.goto("https://www.baidu.com")
# xpath定位输入框，输入文本内容
page.fill('//*[@id="kw"]', "秦时明月")
# css点位点击“百度一下”按钮
page.click('#su')
# 打印title名称
print(page.title)
if __name__ == '__main__':
pytest.main(["-v", "test_baidu_example.py"])
在特定浏览器上运行:
import pytest
from playwright.sync_api import Page
@pytest.mark.only_browser("chromium")
def test_baidu_com(page: Page):
page.goto("https://www.baidu.com")
# xpath定位输入框，输入文本内容
page.fill('//*[@id="kw"]', "秦时明月")
# css点位点击“百度一下”按钮
page.click('#su')
# 打印title名称
print(page.title)
if __name__ == '__main__':
pytest.main(["-v", "test_baidu_example.py"])
忽略 HTTPS 错误和设置自定义视口大小
第一种是写在conftest.py中，然后直接运行测试用例:
# conftest.py
import pytest
@pytest.fixture(scope="session")
def browser_context_args(browser_context_args):
return {
**browser_context_args,
"ignore_https_errors": True,
}
@pytest.fixture(scope="session")
def browser_context_args(browser_context_args):
return {
**browser_context_args,
"viewport": {
"width": 1920,
"height": 1080,
}
}
测试用例写法如下(最好这样写，不然运行就报错，作者已采坑):
import pytest
from playwright.sync_api import Page
def test_example(page: Page):
page.goto("http://www.baidu.com")
assert page.title() == "百度一下，你就知道"
page.close()
if __name__ == '__main__':
pytest.main(["-v", "test_example.py"])
命令行运行测试用例:
PS F:\project_gitee\Test\playwrightProject\cases> pytest --headed --browser chromium
================================================================================== test session starts ==================================================================================

=================================================================================== 1 passed in 2.39s ===================================================================================
第二种是直接在用例中增加指定参数即可:
import pytest
from playwright.sync_api import sync_playwright
def test_example():
with sync_playwright() as p:
browser = p.chromium.launch(headless=False)
page = browser.new_context(
ignore_https_errors=True,
viewport={
"width": 1920,
"height": 1040,
}
)
page = page.new_page()
page.goto("http://www.baidu.com")
assert page.title() == "百度一下，你就知道"
browser.close()
if __name__ == '__main__':
pytest.main(["-v", "test_example.py"])
名词解释:
p.chromium.launch(headless=False):headless=False是开启有页面运行(默认是True，也就是无头浏览器)
第三种是模拟手机浏览器
# conftest.py
import pytest
@pytest.fixture(scope="session")
def browser_context_args(browser_context_args, playwright):
iphone_11 = playwright.devices['iPhone 11 Pro']
return {
**browser_context_args,
**iphone_11,
}
测试用例写法如下(最好这样写，不然运行就报错，作者已采坑):
import pytest
from playwright.sync_api import Page
def test_example(page: Page):
page.goto("http://www.baidu.com")
assert page.title() == "百度一下，你就知道"
page.close()
if __name__ == '__main__':
pytest.main(["-v", "test_example.py"])
命令行运行测试用例:
PS F:\project_gitee\Test\playwrightProject\cases> pytest --headed --browser chromium

这里运行后，打开的web页面，是一个手机形状的页面，仿的是手机浏览器(代码中指定的是iPhone 11 Pro)
持久上下文
它的意思就是打开一个web页面，会在这个web页面开多个新标签页面去执行测试用例。
例如：我有两个测试用例需要执行，如果使用持久上下文，就会打开一个web页面，然后web页面的第一个标签页运行第一个测试用例，第二个标签页运行第二个测试用例，直到把所有测试用例运行完了，关闭整个web页面，结束。
当然，如果你没有使用持久上下文，那就是打开web页面执行第一个测试用例，执行完第一个测试用例关闭web页面，然后再打开web页面执行第二个测试用例，执行完第二个测试用例关闭web页面，结束。
import pytest
from playwright.sync_api import BrowserType
from typing import Dict
@pytest.fixture(scope="session")
def context(
browser_type: BrowserType,
browser_type_launch_args: Dict,
browser_context_args: Dict
):
context = browser_type.launch_persistent_context("./data", **{
**browser_type_launch_args,
**browser_context_args,
"locale": "de-DE",
})
yield context
context.close()
名词解释:
./data用户数据目录的路径，它存储浏览器会话数据，如cookie和本地存储。
browser_type_launch_args如果没有设置值，返回的就是一个空字典；它里面的参数就是和p.chromium.launch()中的传参一致的，此处了解下，后面具体介绍。
browser_context_args如果没有设置值，返回的就是一个空字典；它里面的参数就和context = browser.new_context()中的传参一致的，此处了解下，后面具体介绍。
locale指定用户区域设置，例如' en-GB '、' de-DE '等。
命令行运行测试用例:

必须知晓问题:
上述文章中的browser_type_launch_args和browser_context_args都是pytest_playwright插件提供的测试夹会话：
展示pytest_playwright插件部分源码：
@pytest.fixture(scope="session")
def browser_type_launch_args(pytestconfig: Any) -> Dict:
launch_options = {}
headed_option = pytestconfig.getoption("--headed")
if headed_option:
launch_options["headless"] = False
browser_channel_option = pytestconfig.getoption("--browser-channel")
if browser_channel_option:
launch_options["channel"] = browser_channel_option
slowmo_option = pytestconfig.getoption("--slowmo")
if slowmo_option:
launch_options["slow_mo"] = slowmo_option
return launch_options
@pytest.fixture(scope="session")
def browser_context_args(
pytestconfig: Any,
playwright: Playwright,
device: Optional[str],
) -> Dict:
context_args = {}
if device:
context_args.update(playwright.devices[device])
base_url = pytestconfig.getoption("--base-url")
if base_url:
context_args["base_url"] = base_url
video_option = pytestconfig.getoption("--video")
capture_video = video_option in ["on", "retain-on-failure"]
if capture_video:
context_args["record_video_dir"] = artifacts_folder.name
return context_args
