Smoke testing is a quick test to check if the basic functionalities of the software are working, while sanity testing is a more thorough test to check if the specific changes or fixes made to the software are working as expected.

• Smoke testing is done to ensure the stability of the software build before proceeding with further testing.

• Sanity testing is done to ensure that specific changes or fixes made to the software are working as expected.

• Regression testing is re-testing of...read more

Data flows in our project through various stages including input, processing, and output.

• Examples include user input being validated and stored in a database, or sensor data being processed ...read more

I use techniques like MoSCoW, Kano model, Value vs Effort matrix, WSJF, and Cost of Delay to prioritize the backlog.

• MoSCoW method - Must have, Should have, Could have, Won't have

• Kano model - Basic needs, Performance needs, Excitement needs

• Value vs Effort matrix - High value, Low effort items are prioritized

• WSJF (Weighted Shortest Job First) - Calculating priority based on cost of delay and job size

• Cost of Delay - Prioritizing based on the impact of delaying a task

Action class methods are used to perform keyboard and mouse actions in Selenium.

• Action class is part of Selenium's WebDriver API

• Methods include click(), doubleClick(), contextClick(), dragAndDrop(), etc.

• Used to simulate user interactions with web elements

• SCD Type 2: Creates new records for each change, maintaining history

• SCD Type 3: Adds new columns to track changes without creating new records

• SCD Type 4: Uses separate tables to store historical data

• SCD Type 6: Hybrid approach combining Type 1 and Type 2

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPS focuses on creating objects that interact with each other to solve a problem

• Key principles include encapsulation, inheritance, polymorphism, and abstraction

• Encapsulation: bundling data and methods that operate on the data into a single unit

• Inheritance: allows a class to inherit properties and behavior from another class

• Polymorphism: ability for ob...read more

• OOPS focuses on creating objects that interact with each other to solve a problem

• It involves concepts like classes, objects, inheritance, polymorphism, and encapsulation

• Classes are blueprints for creating objects, while objects are instances of classes

• Inheritance allows a class to inherit properties and behavior from another class

• Polymorphism allows ob...read more
