Selenium SessionNotCreatedException: What It Is and How to Fix It

When you’re running Selenium tests, you may encounter the SessionNotCreatedException. This error can occur for a variety of reasons, but it typically means that Selenium was unable to create a new session with the browser. This can be a frustrating problem, but it’s usually fixable. In this article, we’ll take a look at what the SessionNotCreatedException is, what causes it, and how to fix it.

We’ll start by discussing what the SessionNotCreatedException is and what it means. Then, we’ll look at some of the most common causes of this error. Finally, we’ll provide some tips on how to fix the SessionNotCreatedException so that you can get your Selenium tests back up and running.

What is the SessionNotCreatedException?

The SessionNotCreatedException is a Java exception that is thrown when Selenium is unable to create a new session with the browser. This can happen for a variety of reasons, but it typically means that there is a problem with the Selenium configuration or with the browser itself.

What Causes the SessionNotCreatedException?

There are a number of different things that can cause the SessionNotCreatedException. Some of the most common causes include:

• Incorrect Selenium configuration: If the Selenium configuration is not correct, Selenium may not be able to find the browser or it may not be able to communicate with the browser correctly.
• Browser not running: If the browser is not running, Selenium will not be able to create a session with it.
• Browser not supported: Selenium does not support all browsers. If you are trying to use Selenium with a browser that is not supported, you will get the SessionNotCreatedException.
• Browser extension blocking Selenium: Some browser extensions can block Selenium from communicating with the browser. If you are using a browser extension that blocks Selenium, you will get the SessionNotCreatedException.

How to Fix the SessionNotCreatedException

The SessionNotCreatedException can be a frustrating problem, but it’s usually fixable. Here are a few tips on how to fix the SessionNotCreatedException:

• Check your Selenium configuration: Make sure that the Selenium configuration is correct. This includes the browser name, the browser path, and the port number.
• Make sure the browser is running: If the browser is not running, Selenium will not be able to create a session with it.
• Make sure the browser is supported: Selenium does not support all browsers. If you are trying to use Selenium with a browser that is not supported, you will get the SessionNotCreatedException.
• Disable any browser extensions that might be blocking Selenium: Some browser extensions can block Selenium from communicating with the browser. If you are using a browser extension that blocks Selenium, you will get the SessionNotCreatedException.

The SessionNotCreatedException is a common problem that can occur when running Selenium tests. However, it is usually fixable by checking the Selenium configuration, making sure the browser is running, and disabling any browser extensions that might be blocking Selenium.

How to fix the org.openqa.selenium.SessionNotCreatedException?

The org.openqa.selenium.SessionNotCreatedException is a common error that occurs when Selenium is unable to create a new session. This can happen for a variety of reasons, but some of the most common include:

• The browser is not installed or is not running. Selenium needs to be able to communicate with the browser in order to create a session, so if the browser is not installed or is not running, Selenium will not be able to create a session.
• The browser’s driver is not installed or is not compatible with the browser. Selenium uses drivers to communicate with different browsers, so if the driver is not installed or is not compatible with the browser, Selenium will not be able to create a session.
• The browser’s URL is incorrect. Selenium needs to know the URL of the browser in order to create a session, so if the URL is incorrect, Selenium will not be able to create a session.
• The browser’s port is incorrect. Selenium needs to know the port that the browser is listening on in order to create a session, so if the port is incorrect, Selenium will not be able to create a session.
• The browser’s proxy settings are incorrect. Selenium needs to be able to communicate with the browser through the proxy settings, so if the proxy settings are incorrect, Selenium will not be able to create a session.

If you are getting the org.openqa.selenium.SessionNotCreatedException error, there are a few things you can check to try to fix the problem.

• Check that the browser is installed and running. If the browser is not installed or is not running, Selenium will not be able to create a session.
• Check that the browser’s driver is installed and compatible with the browser. Selenium uses drivers to communicate with different browsers, so if the driver is not installed or is not compatible with the browser, Selenium will not be able to create a session.
• Check that the browser’s URL is correct. Selenium needs to know the URL of the browser in order to create a session, so if the URL is incorrect, Selenium will not be able to create a session.
• Check that the browser’s port is correct. Selenium needs to know the port that the browser is listening on in order to create a session, so if the port is incorrect, Selenium will not be able to create a session.
• Check that the browser’s proxy settings are correct. Selenium needs to be able to communicate with the browser through the proxy settings, so if the proxy settings are incorrect, Selenium will not be able to create a session.

If you have checked all of these things and you are still getting the org.openqa.selenium.SessionNotCreatedException error, you can try the following steps:

• Restart the browser. Sometimes, a simple restart of the browser can fix the problem.
• Restart Selenium. If you are using a Selenium server, you can try restarting the server.
• Reinstall the browser’s driver. If you have recently updated the browser, you may need to reinstall the browser’s driver.
• Reinstall Selenium. If you have recently updated Selenium, you may need to reinstall Selenium.

If you have tried all of these steps and you are still getting the org.openqa.selenium.SessionNotCreatedException error, you can contact Selenium’s support team for help.
