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

Why is this happening, and how can I fix it?

Update your chromedriver with lastest version. And please clarify your question.

If your chrome browser is recently updated to V54.0.x, then you might get this error. The solution for this problem is simply to update your chrome driver.

Choose chrome driver from the below link that will suit your system architecture.

Latest Chromedriver v2.25

This issue started showing up after chrome Version 54.0.x updates. Remove the older chromedriver from your path and update your chromedriver to 2.24. This should resolve your issue.

I had the same issue . Updating the chrome driver solved my problem.

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...

You might be using the lower version of the chrome driver.

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

I had the similar issue and was getting the exception as above. So always check the latest version of driver from here:

You might need to set in /etc/hosts

127.0.0.1 localhost

In my case the problem was that I kept a Selenium script running for too much time than I run out of disk free space.

So, I just clean out the Temp folder and created a routine to keep cleaning selenium folders, and problem solved.

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();
