Answer 1

The error says it all :

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value
(Session info: chrome=65.0.3325.109) 
(Driver info: chromedriver=2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f),platform=Windows NT 10.0.16299 x86_64) 

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

• You are using chromedriver=2.33
• Release Notes of chromedriver=2.33 clearly mentions the following :

Supports Chrome v60-62

• You are using chrome=65.0
• Release Notes of ChromeDriver v2.36 clearly mentions the following :

Supports Chrome v65-66

• Your Selenium Client version is unknown to us.
• Your JDK version is unknown to us.

So there is a clear mismatch between the ChromeDriver version (v2.33) and the Chrome Browser version (v65.0)

Solution

• Upgrade JDK to recent levels JDK 8u162.
• Upgrade Selenium to current levels Version 3.11.0.
• Upgrade ChromeDriver to ChromeDriver v2.36 level.
• Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.36 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Chrome version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Chrome.
• Execute your @Test.

Update :

As per your comment if you are unable to upgrade to ChromeDriver v2.36 you can adopt either of the following strategies :

• Keep chromedriver=2.33 but downgrade to Chrome v60-62
• Upgrade chromedriver=2.34 and downgrade to Chrome v61-63
• Upgrade chromedriver=2.35 and downgrade to Chrome v62-64
