Answer 1

This error message...

urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

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

• You are using chromedriver=2.20
• Release Notes of chromedriver=2.20 clearly mentions the following :

Supports Chrome v43-48

• You are using chrome=68.0
• Release Notes of ChromeDriver v2.41 clearly mentions the following :

Supports Chrome v67-69

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

Solution

• Upgrade ChromeDriver to current ChromeDriver v2.41 level.
• Keep Chrome version between Chrome v67-69 levels. (as per ChromeDriver v2.41 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
• Execute your @Test.
