Q1. Sorting of hashmap using keys without any method. xpath for list of webelements in PageFactory. TARGET folder in maven Data Table in cucumber.
Ans. 
Sorting a hashmap using keys without any method involves iterating through the keys and rearranging them in ascending order.
• Iterate through the keys of the hashmap

• Compare each key with the next key and swap them if they are in the wrong order

• Continue this process until all keys are in ascending order

Q2. Use Set to store all the keys and then perform soting.
Ans. 
Use a Set to store unique keys and sort them for efficient retrieval and organization.
• A Set automatically handles duplicates, ensuring all keys are unique.

• Example: let keysSet = new Set(['key1', 'key2', 'key1']); // keysSet will contain 'key1', 'key2'.

• Convert the Set to an array for sorting: let sortedKeys = Array.from(keysSet).sort();

• Sorting can be done using the default sort method or a custom comparator.

• Example: sor...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...read more

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.

Q8. Difference between parallel methods and parallel tests
Ans. 
Parallel methods run multiple methods concurrently within a single test, while parallel tests run multiple tests concurrently.
• Parallel methods execute multiple methods within a single test class concurrently.

• Parallel tests execute multiple test classes concurrently.

• Parallel methods are useful for speeding up the execution of a single test, while parallel tests are useful for running multiple tests faster.
