Web自动化测试之playwright：设置浏览器语言
playwright支持基于Chromium内核的Google Chrome 和 Microsoft Edge浏览器, WebKit内核的Apple Safari 和 Mozilla Firefox浏览器，可以对浏览器的语言进行设置，可用来测试产品的语言自适应功能。
playwright设置浏览器语言比selenium更简洁，创建浏览器上下文时设置一下 locale 参数：
browser.new_context(locale="zh-CN")
chrome浏览器语言设置示例：
from playwright.sync_api import sync_playwright
class TestBrowser():
def setup(self):
self.playwright = sync_playwright().start()
def teardown(self):
self.browser.close()
def test_chrome(self):
self.browser = self.playwright.chromium.launch(channel="chrome", headless=False)
context = self.browser.new_context(locale="zh-CN") # zh-CN、en-GB
page = context.new_page()
page.goto("https://www.baidu.com/")
lan = page.evaluate("window.navigator.language;")
print(lan)
assert lan == "zh-CN"
Edge，WebKit，Firefox浏览器类似：
def test_edge(self):
self.browser = self.playwright.chromium.launch(channel="msedge", headless=False)
context = self.browser.new_context(locale="de-DE")
page = context.new_page()
page.goto("https://www.baidu.com/")
lan = page.evaluate("window.navigator.language;")
print(lan)
assert lan == "de-DE"
def test_firefox(self):
self.browser = self.playwright.firefox.launch(headless=False)
context = self.browser.new_context(locale="de-DE")
page = context.new_page()
page.goto("https://www.baidu.com/")
lan = page.evaluate("window.navigator.language;")
print(lan)
assert lan == "de-DE"
def test_webkit(self):
self.browser = self.playwright.webkit.launch(headless=False)
context = self.browser.new_context(locale="de-DE")
page = context.new_page()
page.goto("https://www.baidu.com/")
lan = page.evaluate("window.navigator.language;")
print(lan)
assert lan == "de-DE"
上面是同步版本，也可以写成异步方式：
import asyncio
import time
from playwright.async_api import async_playwright
async def test_chrome():
print('test_chrome start')
async with async_playwright() as p:
browser = await p.chromium.launch(headless=False)
context = await browser.new_context(locale="en-US") # zh-CN、en-GB
page = await context.new_page()
await page.goto("https://www.baidu.com/")
lan = await page.evaluate("window.navigator.language;")
assert lan == "en-US"
await browser.close()
print('test_chrome done')
async def test_edge():
print('test_edge start')
async with async_playwright() as p:
browser = await p.chromium.launch(channel="msedge", headless=False)
context = await browser.new_context(locale="en-US") # zh-CN、en-GB
page = await context.new_page()
await page.goto("https://www.baidu.com/")
lan = await page.evaluate("window.navigator.language;")
assert lan == "en-US"
await browser.close()
print('test_edge done')
async def test_firefox():
print('test_firefox start')
async with async_playwright() as p:
browser = await p.firefox.launch(headless=False)
context = await browser.new_context(locale="en-US") # zh-CN、en-GB
page = await context.new_page()
await page.goto("https://www.baidu.com/")
lan = await page.evaluate("window.navigator.language;")
assert lan == "en-US"
await browser.close()
print('test_firefox done')
async def test_webkit():
print('test_webkit start')
async with async_playwright() as p:
browser = await p.webkit.launch(headless=False)
context = await browser.new_context(locale="en-US") # zh-CN、en-GB
page = await context.new_page()
await page.goto("https://www.baidu.com/")
lan = await page.evaluate("window.navigator.language;")
assert lan == "en-US"
await browser.close()
print('test_webkit done')
async def main():
task1 = asyncio.create_task(test_chrome())
task2 = asyncio.create_task(test_edge())
task3 = asyncio.create_task(test_firefox())
task4 = asyncio.create_task(test_webkit())
tasks = [task1, task2, task3, task4]
print('before await')
await asyncio.gather(*tasks)
start = time.time()
asyncio.run(main())
end = time.time()
print('Running time: %s Seconds' % (end - start))
执行结果：
before await
test_chrome start
test_edge start
test_firefox start
test_webkit start
test_chrome done
test_edge done
test_webkit done
test_firefox done
Running time: 17.376961946487427 Seconds
