Hi naveen , great video. one small thing - regarding lines 25,26 I'm not sure it's correct to say that nothing return ( 14:15 , 14:47 ) , since what's actually return is the 'singleton_instance' , which means y,z will point to the same address as x , that's why when you print y.str and z.str you get the same upper case string as x.str

Hey, It looks like there is problem in your example. If we call openBrowser() method twice - than it opened two chrome browsers. So I think we should move this line "driver = new ChromeDriver" or in private constructor or in if block of getInstance method. So after that we avoid of possibility to open two browsers at the same time.

Thank you for the great video, I have a comment: What if you have multiple test methods in your Test Class??? let's say we have another test method called public void test02() {} before this method you're trying to get an instance of WebDriver, it will never create a new instance of our Singleton class (Driverinit), but simultaneously the instance of WebDriver is not null, moreover try to handle any element in the second test method, it will throw (SessionNotCreatedException) as you've already quitted or closed the driver!!!

hello, sir your huge fan. I have one doubt on time 10.38 why you call a static method with classname "Singleton x =Singleton.getinstance();" we can call a method directly "Singleton x = getinstance();" its worked and according to me there no need to call through the class name. please explain it Sir !! thank you !
