Answer 1

The error says it all :

Started InternetExplorerDriver server (64-bit)3.9.0.0 
Exception in thread "main" org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:48107 
Build info: version: '3.11.0', revision: 'e59cfb3', time: '2018-03-11T20:33:15.31Z' 
System info: host: 'UMANATH-PC', ip: '10.1.0.25', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_161' 
Driver info: driver.version: InternetExplorerDriver

It is clear from the error stack trace that InternetExplorerDriver server is not getting detected back as in :

Driver info: driver.version: InternetExplorerDriver

Your main issue is the version compatibility between the binaries you are using as follows :

• You are using Selenium Client v3.11.0
• But you are using InternetExplorerDriverServer v3.9.0.0

So there is a clear mismatch between the Selenium Client v 3.11.0 and InternetExplorerDriverServer v 3.9.0.0 .

Solution

• Upgrade to InternetExplorerDriverServer v 3.11.1.0
