The error says it all :

[RemoteTestNG] detected TestNG version 6.14.2 Starting ChromeDriver (v2.9.248307) on port 34979

Your main issue is the version compatibility between the binaries you are using as follows :

You are using chromedriver=v2.9
Release Notes of chromedriver=2.9 clearly mentions the following :

Supports Chrome v31-34

Your Chrome Browser version is unknown to us. (assuming Chrome Browser is updated to v65.x level)
Your Selenium Client version is 3.10.0.
Your JDK version is 1.8.0_101 which is pretty ancient.

So there is a clear mismatch between the JDK v8u101 , Selenium Client v3.10.0 , ChromeDriver version (v2.9) and the current Chrome Browser version (v65.0)

Solution

Upgrade JDK to recent levels JDK 8u162.
Keep Selenium to current levels Version 3.10.0.
Upgrade ChromeDriver to stable ChromeDriver v2.36 level.
Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.36 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Chrome version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Chrome.
Execute your @Test.

Hi I have this weird issue. I am not able to run tests with chromedriver on my Mac. I have searched every possible corner here and none seems to help. My browser is launched, but it freezes just before the driver.get(url) is called.

My environment: MacOS High Sierra, Latest chromedriver as of 12March 2018, Latest selenium 3.10, Latest TestNG 6.14

My code:
```
public class Temp {

@Test()
public void test1() {
    System.setProperty("webdriver.chrome.driver", "src/test/resources/chromedriver");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--test-type");
    options.addArguments("ignore-certificate-errors");
    WebDriver driver = new ChromeDriver(options);
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.manage().window().maximize();

    driver.get("https://www.google.co.in/");
    driver.quit();
}
}
```
Exception I'm getting is:

Additional Info: I have tried to do a regression by using older version of chromedriver, older version of TestNG, older version of selenium, but none seems to be working.

Thanks in advance.

Thank you for quick help over this. I tried multiple things except pointing eclipse to my current Java. I will give it a try and keep this thread posted.

Updating to Chromedriver 2.36 solved my issue. I have marked your answer as 'Accepted'. Thanks!
