Java Selenium Chrome driver - Disable logging

Question

I'm working with Selenium Chrome driver and want to disable logging, I'v tried all existing solutions including :

ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.addArguments("--log-level=3");

and

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
        capabilities.setCapability("chrome.verbose", false);

but none worked for me, still having this Info and warning log showing up :

Starting ChromeDriver 2.25.426924 (649f9b868f6783ec9de71c123212b908bf3b232e) on port 17965 Only local connections are allowed.

Answer 1

This is what I have been doing and it has worked so far for me.

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArgument("--log-level=3");
chromeOptions.addArgument("--silent");
WebDriver driver = new ChromeDriver(chromeOptions);

Answer 2

Only --log-level=3 works for me, tested on: Ruby, watir, selenium 3.142.3, chromedriver 75.0.3770.140 , win 10

Ruby code:

   options = Selenium::WebDriver::Chrome::Options.new

    default_options = %w[--log-level=3]
    default_options.each do |option|
      options.add_argument(option)
    end

    @driver = Watir::Browser.new :chrome, options: options

Answer 3

运行chromedriver --help它说明如果您想关闭注销，您需要添加参数“--silent”（不记录任何内容（相当于 --log-level=OFF），换句话说：

chromeOptions.addArgument("--silent");

Answer 4

For Minimum output you can use the below code -

System.setProperty("webdriver.chrome.silentOutput", "true");
java.util.logging.Logger.getLogger("org.openqa.selenium").setLevel(Level.OFF);
