Passing options to chrome driver selenium

Question

I am trying to disable the output to the console for chrome. If I pass the --start-maximized option it works fine. I may have the wrong command?

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--silent"));
chrome = new ChromeDriver(_chromeservice,capabilities);

I also tried

 ChromeOptions options = new ChromeOptions();
 options.addArguments("silent");
 chrome = new ChromeDriver(options);

Output

Started ChromeDriver port=26703 version=23.0.1240.0 log=/Brett/workspace/TestNG/chromedriver.log [1214/161331:ERROR:ipc_sync_channel.cc(378)] Canceling pending sends [1214/161331:ERROR:ipc_sync_channel.cc(378)] Canceling pending sends [1214/161331:ERROR:ipc_sync_channel.cc(378)] Canceling pending sendsBlockquote

Is silent a valid switch? The way you are sending the switch is correct..Is disabling the logging is what you want? — niharika_neo, Dec 17 '12 at 06:03
If you are trying to pass switches directly to chrome, then `--silent` is not a valid switch. Here [link](http://peter.sh/experiments/chromium-command-line-switches/) is a list of valid switches. — mleczey, Jan 09 '13 at 08:04

Hinted by this Chromedriver ticket (about the silent option), I looked in the source of ChromeDriverService.java, and found a reference to "webdriver.chrome.logfile".

After adding -Dwebdriver.chrome.logfile="/dev/null" to my java command, the logs became readable again: The usless ChromeDriver logs were gone, while theSystem.out.println calls and exceptions are still shown in the console.

I start java with the following parameters (Linux / Mac):

DIR=path/to/dir/containing/selenium/and/stuff
cd "$DIR" && java -cp "$DIR\
:$DIR/output\
:$DIR/bin/selenium-server-standalone-2.33.0.jar" \
-Dwebdriver.chrome.driver="$DIR/bin/chromedriver" \
-Dwebdriver.chrome.args="--disable-logging" \
-Dwebdriver.chrome.logfile="/dev/null" \
AllTests

If you're on Windows:

set DIR=path\to\dir\containing\selenium\and\stuff
cd "%DIR%" && java -cp "%DIR%;%DIR%\output;%DIR%\bin\selenium-server-standalone-2.33.0.jar" ^
-Dwebdriver.chrome.driver="%DIR%\bin\chromedriver.exe" ^
-Dwebdriver.chrome.args="--disable-logging" ^
-Dwebdriver.chrome.logfile=NUL ^
AllTests

Explanation for the composition of my classpath (-cp): My tests are located in a directory at "$DIR/output". The Selenium jar file is placed in "$DIR/bin/selenium-server-standalone-2.33.0.jar". "AllTests" is the name of my class containing public static void main(String[] args) - this launches my tests.

The other parameters are self-explanatory, adjust it to your needs. For convenience (used in a shell/batch script), I've declared the common directory in a variable DIR.

Could you clearly explain how to use it in Java and Windows. I mean please add your code — user2087450, Jul 04 '13 at 13:29

When I was setting chrome up with

  selenium-chrome-driver-2.48.2.jar
  chromedriver 2.20
  selenium-java-2.48.2.jar

none of the above answers worked for me, Since I see some of the answers are a few years old, I will post what worked for me.

    ChromeOptions chromeOptions = setupChromeOptions();
    System.setProperty("webdriver.chrome.logfile", "\\path\\chromedriver.log");
    System.setProperty("webdriver.chrome.driver", "\\path\\chromedriver.exe");
    System.setProperty("webdriver.chrome.args", "--disable-logging");
    System.setProperty("webdriver.chrome.silentOutput", "true");
    driver = new ChromeDriver(chromeOptions);

Bingo. I needed `logfile`, `args` AND `silentOutput`. The output looks so much nicer now. Proof that small things make a big difference. — Sridhar Sarnobat, Nov 30 '16 at 04:50

Try "--disable-logging" instead.

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--disable-logging"));
chrome = new ChromeDriver(_chromeservice,capabilities);

Thanks for your reply. I tried it and it's still outputting the same information. – Lazadon Jan 23 '13 at 14:27

BTW what you see are not really errors per say, since they are not affecting chrome driver execution in any way, right? – Ashwin Prabhu Jan 24 '13 at 05:48
No it does not effect the execution of any tests. I am just thinking down the line. After a while it will take up a lot of space in the log file. – Lazadon Jan 24 '13 at 16:06

As of Selenium 3 at least, you can use ChromeDriverService and its inner class Builder to be able to launch the driver in silent mode.

A oneliner for that:

new ChromeDriver(new ChromeDriverService.Builder().withSilent(true).build());

The constructor is straight-forward, you create a new service builder setting silent to true (that's the critical part) and you finally build it into a ChromeDriverService which is required by ChromeDriver's constructor.
