org.openqa.selenium.NoSuchSessionException: no such session error in Selenium automation tests using ChromeDriver Chrome with Java

Question

Getting "No such session exception" while running selenium in my pipeline. I find many solutions related it but none worked for me. Any assistance or idea? Exception trace:

I have checked in code; there is no driver.close() or driver.quit() is used.Tests are running successfully sometime and sometimes are failing.

Can any one help me for this issue?

This error message...

org.openqa.selenium.NoSuchSessionException: no such session

...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=2.38
Release Notes of chromedriver=2.38 clearly mentions the following :

Supports Chrome v65-67

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

Supports Chrome version 79

Your Selenium Client version is 3.9.1 of 2018-02-07T22:25:02.294Z which is almost 2 years older.
Your JDK version is 1.8.0_121 which is pretty ancient.

So there is a clear mismatch between JDK v8u121 , Selenium Client v3.9.1 , ChromeDriver v2.38 and the Chrome Browser v79.0

Solution

Ensure that:

JDK is upgraded to current levels JDK 8u232.
Selenium is upgraded to current levels Version 3.141.59.
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 through Revo Uninstaller and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your @Test as non-root user.

If you getting this issue on executing testng.xml ( having many testcases ), there might be many reasons:

-Appium/web driver instance running on single port is not overriding for next testcase and so session not created.

-No close/quit browser

-webDriver used in first testcase is not returned to run the next testcase ( local thread driver terminating somewhere)

-No wait time between two testcases.
