Unsupported Command-line Flag: --ignore-certificate-errors

Using Python 2.7.5, python module selenium (2.41.0) and chromedriver (2.9). When Chrome starts it displays a message in a yellow popup bar: 'You are using an unsupported command-li

Solution 1:

This extra code removes the --ignore-certificate-errors command-line flag for me. In my opinion the arguments that can be added to webdriver.Chrome() could (and should) be better documented somewhere, I found this solution in a comment on the chromedriver issues page (see post #25).

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ["ignore-certificate-errors"])
browser = webdriver.Chrome(chrome_options=options)
browser.get("http://google.com/")

Solution 2:

This issue is resolved as of Chromedriver 2.11 (released Oct 2014). Updating will now do the trick.

Solution 3:

you can use the following flag --test-type

var options = new ChromeOptions();
            options.AddArguments(new[] {
                "--start-maximized",
                "allow-running-insecure-content", 
                "--test-type" });

            returnnew ChromeDriver(options);

Solution 4:

This is what I'm currently using in Java to get around this issue but I don't know how Python works but worth a try anyway

ChromeOptions chrome = new ChromeOptions();
chrome.addArguments("test-type");
        capabilities.setCapability(ChromeOptions.CAPABILITY, chrome);
        capabilities.setCapability("chrome.binary",
                "C:\\set path to driver here\\chromedriver.exe");

Solution 5:

    options = webdriver.ChromeOptions()

    options.add_argument('test-type')
    chromedriver = 'resources/chromedriver.exe'os.environ["webdriver.chrome.driver"] = chromedriver

    self.driver = webdriver.Chrome(chromedriver,chrome_options=options)
