Q1. Difference between Severity, Priority and criticality?

Severity, Priority, and Criticality are different aspects of issue management in software testing.
• Severity refers to the impact of a defect on the system's functionality.

• Priority indicates the order in which defects should be fixed based on business needs.

• Criticality combines severity and priority to determine the overall importance of a defect.

• For example, a defect causing a system crash would have high severity, high...read more

Q2. What id Equivalence partitioning?
Ans. 
Equivalence partitioning is a software testing technique where input data is divided into partitions and only one value from each partition is tested.
• Input data is divided into groups or partitions based on similar characteristics

• One value from each partition is selected as a representative for testing

• Helps in reducing the number of test cases while ensuring maximum coverage

• Example: Testing a login form with valid, inv

Q3. What id BackWord Compatibility?
Ans. 
Backward compatibility refers to the ability of a system to accept input intended for an older version of the system.

Q3. How is encapsulation different than abstraction?
Ans. 
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, while abstraction is the concept of hiding the implementation details and showing only the necessary features of an object.
• Encapsulation is about wrapping the data (variables) and methods (functions) that operate on the data into a single unit (class).

• Abstraction is about hiding the implementation details and showing ...read more

Q4. What do you mean by run time polymorphism and how is it achieved?
Ans. 
Run time polymorphism is the ability of a method to do different things based on the object it is acting upon.
• Run time polymorphism is achieved through method overriding in object-oriented programming.

• It allows a subclass to provide a specific implementation of a method that is already provided by its superclass.

• The actual method that gets called is determined by the type of object at run time.

• Example: Animal class has...read more
