I've been looking at the following article about Headless Chrome: https://developers.google.com/web/updates/2017/04/headless-chrome I just upgraded Chrome on Windows 10 to version 60, but when I run either of the following commands from the command line, nothing seems to happen: chrome --headless --disable-gpu --dump-dom https://www.google.com/ chrome --headless --disable-gpu --print-to-pdf https://www.google.com/ And I'm running all of these commands from the following path (the default installation path for Chrome on Windows): C:\Program Files (x86)\Google\Chrome\Application\ When I run the

I'm do me code in Cromedrive in 'normal' mode and works fine. When I change to headless mode it don't download the file. I already try the code I found alround internet, but didn't work. chrome_options = Options() chrome_options.add_argument("--headless") self.driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'{}/chromedriver'.format(os.getcwd())) self.driver.set_window_size(1024, 768) self.driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command') params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow',

In headless mode, Chrome defaults to disallowing file downloads. However, recently they added an option to DevTools to enable this behavior: https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-setDownloadBehavior Using Selenium with ChromeDriver in Python, how do I allow file downloads? For those who are still looking , That's how i did it : def enable_download_in_headless_chrome( driver, download_dir): #add missing support for chrome "send_command" to selenium webdriver driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')

I have a WebDriver testsuite, which operates different when I execute it in normal and headless browser. There is an element which is not found when I execute it in headless mode, but found when I use the same code, same driver in normal mode. I use this flag to set headless mode: chromeOptions.addArguments("--headless"); There is ChromeDriver 2.31 and WebDriver 3.5.2 in use. How could I debug this? There are two ways to debug. You can get Page Source and check what is different. Now when you launch a browser using Selenium, it is using the Debugging session to automate chrome. So you can't do
