Hi Naveen.. you are doing an incredible job.. really like the way you teach :) My concern is that, isn't it necessary to make the CONSTRUCTOR of the class PRIVATE in order to achieve SINGLETON so that nobody is allowed to explicitly create an object of the class from outside?

@maheshnair1774 4 года назад

Hi Naveen is it possible to achieve parallel execution with singleton design pattern since only one instance of driver will be invoked at a time ?

@manikannanmarimuthu9232 6 лет назад

Hi Naveen, The way your are explaining is pretty good. Hats-off to you.

@mahireddyporeddy9594 6 лет назад

Hi, Naveen ! It was a really cool video. Everybody on the web talks a lot about patterns but that is very important to show how to use them in projects. I ask you to do more videos related to implementation other patterns in framework. Thanks a lot!!!!

@KarthikD72 5 лет назад

Appreciated !!! . Can you make video On Singleton behavior during parallel execution . Thanks

@suman_mathad 11 месяцев назад

How can you call this a singleton pattern when you have not made the constructor of the class as private? I mean, anyone can still create a new object of this class and that is not singleton anymore.

Ok I understood

@vinodbalavel8813 Год назад

Hello Naveen, Very useful video. One query. How will you handle SingleSignOn applications when we require multiple login in the test flow involved? The only way to have multiple login is to close the browser as its SSO. Will this impact us when we move on to parallel execution?

@solyog23 6 лет назад

Sir I have 1question, If we making webdriver static, How it will reflect parallel browser testing Using Grid?

@naveenautomationlabs 6 лет назад

You can achieve singleton without static as well. I have just given an example with static. You can create WebDriver driver instance without static as well.

@solyog23 6 лет назад

@@naveenautomationlabs thank you sir for reply, but I have another question it will create instance of each webdriver, so is there it will consume more memory on Heap?

@chitaranjansahoo9243 7 месяцев назад

Sir, How we get the Testbase class driver to any pages while we define any method like loginPage , homepage . not test class, because we are not extending the Testbase class

@prasadneeli8215 5 лет назад

Hi Naveen,i still have doubt ,where exactly this singleton pattern is benefited in Selenium web driver because web driver instance is creating and destroying for every test case

@kishanchakra 6 лет назад

Hi Naveen, i have a question. So the singleton method that we have written, should it be always a static one?

@naveenautomationlabs 6 лет назад

Not compulsory

@udemytesters 3 года назад

I think here we can create multiple instances , no where it is restricted it seems. Correct me if i am wrong.

@anjalilahariya1849 3 года назад

Naveen i do have question in singelton we use private reference variable but you use here as public may I know the reason why you have used public instead of private

@likeminds925 2 года назад

FreecrmTest is not extending the TestBase class, is it not reuired ?

@ravinaidu4035 6 лет назад

Hi naveen. In initialize we have two drivers .Both chrome and firefox How the system knows we have to use chrome

@sudipmitra292 2 года назад

Can we run parallel test in multiple thread with singleton design pattern ?

@muaazster 2 года назад

Can we use page object model with singleton pattern

@vikalpandey937 4 года назад

Hi Naveen, please make a vedio on Cucumber Parallel feature file execution on a same or different browser, till now this vedio is pending

@geethamaddirala 6 лет назад

Why driver to null, not understand pls tell me anyone

@user-jz2sn3xm4c Год назад

I think it should be 'private static Webdriver driver = null' instead of public.

@sdet-byrahulmandve8967 6 лет назад

Hi naveen Can we use beforemethod instance of beforeclass

@naveenautomationlabs 6 лет назад

Yes watch full video. You will get to know :)

@sdet-byrahulmandve8967 6 лет назад

Thanks naveen yes I got it

@anyaslol 2 года назад

Hi Naveen, I have framework based on singleton design pattern +Cucumber + TestNG where I tried to execute the cucumber feature file scenarios in parallel but it did not work. Can we use singleton webdriver in parallel execution. Please clarify.

@bsubu29 Год назад

I was just thinking of commenting on the same. If you want to have parallel test and make your driver as static in singleton class, it will not work. Singleton means, you will have a single instance. so you can not create multiple instance of your driver, hence parallel test will fail.

@ravinaidu4035 6 лет назад

Chrome is taken if statement then how can we mention use firefox driver
