Q2. Where you initialise driver
Ans. 
The driver is typically initialized in the setup method of a test automation framework.
• Driver initialization is usually done in a setup method before test execution.

• Commonly used methods for driver initialization include WebDriverManager, System.setProperty, and driver instantiation.

• Example: WebDriverManager.chromedriver().setup();

Q3. Driver is static or non static
Ans. 
Driver can be both static and non-static depending on the context of its usage.
• Driver class can be static if it is used to initiate the WebDriver instance in a test automation framework.

• Driver class can be non-static if it is used as an instance variable within a test class.

• Static driver can be accessed directly without creating an object of the class.

• Non-static driver requires an object of the class to be created befo

Q4. Difference between static and non static
Ans. 
Static variables belong to the class itself, while non-static variables belong to instances of the class.
• Static variables are shared among all instances of a class

• Non-static variables are unique to each instance of a class

• Static variables are initialized only once, at the start of the program

• Non-static variables are initialized separately for each instance of the class

Q5. Disadvantages of static and non static
Ans. 
Static and non-static have their own disadvantages in QA automation testing.
• Static methods cannot be overridden or inherited, making it difficult to create flexible test cases.

• Non-static methods require an instance of the class to be created, which can lead to increased memory usage.

• Static methods can lead to tight coupling between classes, making it harder to maintain and update the code.

• Non-static methods may have de...read more

Q7. Write the code for Parallel testing in TestNG
Ans. 
Parallel testing in TestNG allows running tests concurrently for faster execution.
• Use 'parallel' attribute in testng.xml file to specify parallel execution mode.

• Set 'parallel' attribute to 'methods', 'classes', or 'tests' based on the level of parallelism needed.

• Example: <suite name='MySuite' parallel='tests'>

• Use 'thread-count' attribute to specify the number of threads to use for parallel execution.
