How to disable logging of ChromeDriver using Selenium and JavaFX

Question

When I run my app java is always writing things like:

Starting ChromeDriver 2.42.591088 (7b2b2dca23cca0862f674758c9a3933e685c27d5) on port 19943
Only local connections are allowed.

INFO: Detected dialect: OSS

How can I prevent it? I don't need it now.

Answer 1

These logs you mentioned are the default ChromeDriver startup logs. As the log level is not configured until a session is created you don't have any control over the generation of these logs.

Moving forward, during Test Execution to see lesser logs you can simply pass --silent argument to the chromedriver server as follows:

• Code Block:

    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.chrome.ChromeDriver;
  
    public class A_Chrome_General
    {
        public static void main(String[] args) 
        {
            System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
            System.setProperty("webdriver.chrome.silentLogging", "true");
            WebDriver driver = new ChromeDriver();
            driver.get("https://stackoverflow.com");
            System.out.println("Page Title is : "+driver.getTitle());
            driver.quit();
        }
    }
