...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context 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=78.0
• Release Notes of chromedriver=78.0 clearly mentions the following :

Supports Chrome v78

• You are using chrome=79.0
• Release Notes of ChromeDriver v79.0 clearly mentions the following :

Supports Chrome 79

So there is a clear mismatch between the ChromeDriver v78.0 and the Chrome Browser v79.0

Solution

Ensure that:

• ChromeDriver is updated to current ChromeDriver v79.0.3945.36 level.
• Chrome is updated to current Chrome Version 79.0 level. (as per ChromeDriver v79.0 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.
• Take a System Reboot.
• Execute your @Test as non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
