org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session error with Selenium and IE11 using Java
This error message...
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session.......implies that the IEDriverServer was unable to initiate/spawn a new WebBrowsing Session i.e. InternetExplorer Browser session.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
- Your Selenium WebDriver Client version is 3.12.0 which is a bit older.
- Your InternetExplorerDriver version 3.150.1.
So there is a clear mismatch between Selenium Client v3.12.0 , IEDriverServer v3.150.1.
Solution
- Upgrade Selenium to current levels Version 3.141.59.
- Upgrade IEDriverServer to IEDriverServer v3.141.59 or IEDriverServer v3.150.0 level.
- Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
- Execute your
Testas a non-root user. - Always invoke
driver.quit()withintearDown(){}method to close & destroy the WebDriver and Web Client instances gracefully.
