Q1. What is the output of below code public class Test { public static void main(String[] args) { int I = 0; try { throw new NullPointerException(); // Exception is thrown ...read more
Ans. 
The code demonstrates exception handling, resulting in an output of 2 due to incrementing variable I in catch and finally blocks.
• The code throws a NullPointerException which is caught in the catch block.

• In the catch block, I is incremented from 0 to 1.

• The finally block executes regardless of exception, incrementing I from 1 to 2.

• The final output printed is the value of I, which is 2.

Q2. What is the process to find duplicate names from a string array and print those that start with the letter 'B'?
Ans. 
Identify and print duplicate names from a string array that start with 'B'.
• 1. Create a string array with names, e.g., ['Bob', 'Alice', 'Bill', 'Bob', 'Bobby'].

• 2. Use a HashMap or dictionary to count occurrences of each name.

• 3. Iterate through the array and check for names starting with 'B'.

• 4. Print names that have a count greater than 1, e.g., 'Bob' and 'Bill' if they are duplicates.

Q4. What tags have you used in the runner class?
Ans. 
In a runner class, tags help organize and filter test cases for execution in automation testing frameworks.
• Tags are used to categorize tests, e.g., @smoke, @regression.

• They allow selective execution, e.g., running only @smoke tests.

• Tags can be combined, e.g., @regression and @critical.

• In Cucumber, tags are specified in the feature file, e.g., @login.

• In TestNG, tags can be implemented using groups in XML configuration.

Q5. What is the difference between regression testing and smoke testing?
Ans. 
Regression testing checks existing features after changes, while smoke testing verifies basic functionality post-deployment.
• Regression testing ensures that new code changes do not adversely affect existing functionalities.

• Smoke testing is a preliminary test to check if the basic functions of an application work.

• Example of regression testing: After a new feature is added, testing all existing features to ensure they sti...read more

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.
