问题
I am running python selenium tests using headless chrome. After updating to chrome Version 76.0.3809.87 and chromedriver version ChromeDriver 76.0.3809.68, the chromeOptions that I use (see code sample below)... no longer work. i.e. the browser is launched (non headless) and the resolution settings are also not working
Anyone else seeing this after upgrading to chromedriver 75/76?
chrome_options = {'args': ['headless', '--window-size=1920,1080', 'no-sandbox', '--dns-prefetch-disable','--disable-dev-shm-usage']}
capabilities = {'browserName': 'chrome', 'chromeOptions':chrome_options}
cls.driver = webdriver.Chrome(desired_capabilities=capabilities)
回答1:
You don't need to use desiredCapabilities to pass these arguments you can use Options instead. I have tested and it works.
Google Chrome - 76.0.3809.87
ChromeDriver - 76.0.3809.68
Selenium - 3.141.0
Python - 3.7.2
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.headless = True
driver = webdriver.Chrome(options=options)
driver.get('https://www.google.com')
driver.save_screenshot("screenshot.png")
driver.quit()
Check the screenshot obtained from the headless browser below.
