Software Testing Techniques: White-Box, Model-Based, and More
Question 1: White-Box Testing
What is a key characteristic of white-box test techniques?
Answer: (b) They are used both to measure coverage and to design tests to increase coverage.
Question 3: Model-Based Testing
What is Model-Based Testing?
Model-Based Testing (MBT) is a software testing approach where test cases are derived from a model representing the system’s behavior, requirements, or processes.
Question 4: Pairwise & Neighborhood Integration
Pairwise Integration:
- A testing technique where
V-Model SDLC: Verification and Validation in Software Development
Understanding the V-Model in SDLC
The V-model is a type of SDLC (Software Development Life Cycle) model where the process executes in a sequential manner, forming a V-shape. It is also known as the Verification and Validation model. This model is based on the association of a testing phase for each corresponding development stage. Each development step is directly associated with a testing phase. The next phase starts only after the completion of the previous phase; for each development activity,

Functional Decomposition Diagrams (DDF)
Techniques to represent the decomposition of the functions of a system.
Its purpose is to represent the hierarchy of system processes at different levels of abstraction. It decomposes a high-level function into low-level functions.
They are used to represent other information such as company structure.
Types of DDF
- Functions of the system at different levels of abstraction but without considering the flows between them.
- The functions and input and output data
- Functions
Understanding Use Cases in Software Engineering
In software engineering, a use case is a technique for capturing potential requirements of a new system or a software update. Each use case provides one or more scenarios that show how the system should interact with the user or another system to achieve a specific goal.
Types of Use Cases
Brief Use Case
A few paragraphs of prose that usually only include the main stage for success.
Casual Use Case
Several paragraphs that contain several scenarios, but by no means all in detail.
- Name
- Main Stage, written
Software Quality Assurance: Concepts and Techniques
Understanding Errors in Software Development
An error is a fault in a program that causes unexpected behavior or failure. Errors stem from incorrect logic, invalid input, hardware failures, or software bugs.
Types of Errors
Syntax Errors – Violate language rules, preventing execution.
Example:
print("Hello, World" # Missing parenthesisFix: Follow correct syntax.
Logical Errors – Code runs but gives incorrect output.
Example:
def add(a, b): return a - b # Wrong logicFix: Debug logic carefully.
Software Engineering Essentials: Principles and Practices
Introduction to Software Engineering
Software engineering is a discipline through which we develop or create software for computer systems and other electronic devices. It is a process where user needs are analyzed, and software is designed based on these needs. Software engineering defines scientific principles, methods, and procedures. Software engineers build software and applications using design and programming languages.
To create complex software, we should use engineering techniques. To reduce
