Mastering Parallel Execution: Overcoming Challenges in Selenium Testing || TestNG

Hello Everyone,
Welcome to my channel PrinceAutomationDestination.
🚀 Parallel Execution Challenges & Resolution in TestNG:
📌 Parallel Execution is one of the important aspect of Test Automation framework as it helps in achieving quick execution.
As a result it become important Interview question to Automation Engineers. So, Today's topic is parallel Execution challenges and resolution in TestNG Framework.
📌 How do you achieve parallel Execution in your TestNG based Automation Framework
Answer from most of people is:
1. provide parallel = methods|tests|class
2. provide thread-count=2|3|4|5
But are not aware about, How thread safety is being taken care i.e. how to avoid interference of parallelly executing Threads.
📌 Challenges with Automation Implementation:
✅ We need a single isolated driver per Thread and by default when we create static/Singleton driver instance, it is not Thread Safe
So, We get Thread Interference and as a result we get uneven results of execution and come across following errors
1. NullPointerException
2. SessionNotCreated
3. NoSuchElementException
4. and So On
📌 BIG Question is: How to resolve it
✅ There is a concept of Thread Local Class in Java using which we can store the value of variable for each thread and same thread would be able to retrieve it and thus avoid interference of threads.
✅ So we are going to use the same concept in case of Parallel Execution by creating Thread Local Instance for both static as well as Singleton Instances

This is one of the hidden gem on TestNg with parallel execution challenges. Nicely explained . Hats off

[@PrinceAutomationDestination]

Thanks buddy

[@balajivivek8662]

Is there similar content for test data management , test report management for parallel execution.

[@PrinceAutomationDestination]

Not so far but I will try creating soon

[@balajivivek8662]

@@PrinceAutomationDestination ok thanks for the consideration . I think the test data supply via data providers or json should be thread safe . Else it will create a issue in parallel executions . The same applies to reporting as well when we are using extent report or allure .. All should be thread safe

[@balajivivek8662]

Awaiting your video for the above mentioned challenges.

Hi
Can you please suggest similar examples using junit also!? How the code you have written should work with junit !?
And thanks for the clear n precise explanation 🙏

[@PrinceAutomationDestination]

Junit 5 ?

[@throwyourmindat]

@@PrinceAutomationDestination yes please

[@PrinceAutomationDestination]

Sure

[@hashirhasmy1042]

is it possible to assign returning driver value from singelton class to normal driver like this from test case having class.
Webdriver driver = CrrateDriver.getInstance.getDriver();
is this approach fine to use driver reference variable in side test class

[@PrinceAutomationDestination]

Yes
