Q4. Difference between static and dynamic binding in java
Ans. 
Static binding occurs at compile time, while dynamic binding happens at runtime in Java.
• Static binding is resolved during compile time, e.g., method overloading.

• Dynamic binding is resolved during runtime, e.g., method overriding.

• Static binding is faster as it doesn't involve runtime overhead.

• Dynamic binding allows for polymorphism, enabling flexible code behavior.

Q5. What is an abstract class and interface in java
Ans. 
Abstract classes and interfaces are key concepts in Java for defining abstract types and enforcing contracts for classes.
• An abstract class can have both abstract methods (without implementation) and concrete methods (with implementation).

• An interface can only have abstract methods (prior to Java 8) and default methods (from Java 8 onwards).

• A class can extend only one abstract class but can implement multiple interfaces...read more

Q7. Selenium script for fetch data from table using index
Ans. 
Selenium can fetch data from a table using index by locating elements and iterating through rows and cells.
• Locate the table using XPath or CSS selectors, e.g., driver.findElement(By.xpath('//table')).

• Use findElements to get all rows: List<WebElement> rows = driver.findElements(By.xpath('//table/tbody/tr')).

• Iterate through rows and fetch data using index: String cellData = rows.get(rowIndex).findElements(By.tagNam...read more

Q10. Put and patch method difference
Ans. 
PUT replaces a resource, while PATCH updates a resource partially.
• PUT is idempotent; multiple identical requests have the same effect as a single request.

• PATCH is not necessarily idempotent; repeated requests may yield different results.

• Example of PUT: Updating a user's profile by sending the entire profile data.

• Example of PATCH: Updating just the user's email address without affecting other fields.

Q12. How to handle failed scenarios in your framework
Ans. 
Implementing robust handling for failed scenarios ensures reliability and aids in debugging within a QA framework.
• Use logging to capture detailed error messages and stack traces for failed tests.

• Implement retry logic for flaky tests to reduce false negatives. For example, retry a network call up to three times.

• Categorize failures into critical and non-critical to prioritize fixes. Critical failures halt the pipeline, w...read more
