Here are a few common scenarios that can lead to this exception:
- Driver Configuration Issues: If your driver configuration is incorrect or incompatible with the browser version you're using, it might result in a session not created exception. Ensure that you're using the appropriate WebDriver version for your browser.
- Incorrect WebDriver Path: If the path to the WebDriver executable is incorrect or not accessible, Selenium won't be able to create a new session. Make sure you're providing the correct path to the WebDriver executable.Driver Configuration Issues: If your driver configuration is incorrect or incompatible with the browser version you're using, it might result in a session not created exception. Ensure that you're using the appropriate WebDriver version for your browser.
- Browser Version Mismatch: If you're using an outdated version of the WebDriver that doesn't support the browser version you're trying to automate, you might encounter this exception. Update your WebDriver to a version that's compatible with your browser.
- Browser Configuration: Some browsers, like Chrome, require additional configurations to work with Selenium. For instance, you might need to specify the path to the Chrome binary using the chrome.binary property.
- Firewall or Network Issues: Network connectivity issues, firewall restrictions, or proxy settings can also prevent Selenium from creating a new session. Check your network settings and ensure that Selenium can establish a connection to the browser.
- Driver Initialization: If you're not initializing the WebDriver correctly before trying to create a session, you'll likely encounter this exception. Make sure you're creating an instance of the WebDriver and setting up any necessary configurations before attempting to start a session.
- Runtime Environment: If you're running Selenium tests in a specific runtime environment (like a server or a CI/CD pipeline), make sure that environment has the necessary dependencies and configurations to run Selenium successfully.
