org.openqa.selenium.SessionNotCreatedException: session not created exception

Question

I\'m trying to run some Selenium tests using the ChromeDriver, and I started getting this error:

Starting ChromeDriver 2.23.409699 (49b0fa931cda1caad0ae15b7d         


        

Answer 1

A few things to bare in mind for these type of cases:

• Disable browsers auto update - at least on your slaves to avoid these type of breaking your CI process. Link for how to on Chrome, and be sure to watch these settings on the installation.
• Versioning is the first thing to check with Selenium when it breaks all of a sudden. See notes for version compatibility.
• I'm using my own Maven plugin to check compatibility between chromedriver and Chrome version

Hope it helps...

Answer 2

You will get this error when your code looks like below:

WebDriver driver = new ChromeDriver();
System.setProperty("webdriver.chrome.driver", "C:\\driver\\chromedriver.exe");

You have to setProperty first and then create driver instance next

System.setProperty("webdriver.chrome.driver", "C:\\driver\\chromedriver.exe");
WebDriver driver = new ChromeDriver();

You might need to set in /etc/hosts
