Introduction to SOLID Principles

• Overview of the SOLID principles and their significance in software design
• Understanding the benefits of adhering to SOLID principles
• Introduction to the five SOLID principles

Single Responsibility Principle (SRP)

• Understanding the concept of a single responsibility for a class or module
• Designing classes and methods that have a single, well-defined responsibility
• Identifying and refactoring code that violates the SRP

Open/Closed Principle (OCP)

• Understanding the principle of being open for extension but closed for modification
• Designing classes and components that are easily extendable without modifying existing code
• Applying techniques such as inheritance, composition, and interfaces to adhere to the OCP

Liskov Substitution Principle (LSP)

• Understanding the concept of substitutability and behavioral compatibility
• Ensuring that subclasses can be used interchangeably with their base classes
• Identifying and resolving violations of the LSP

Interface Segregation Principle (ISP)

• Understanding the principle of segregating interfaces to avoid unnecessary dependencies
• Designing cohesive and focused interfaces that meet the specific needs of clients
• Avoiding the pitfalls of large, monolithic interfaces

Dependency Inversion Principle (DIP)

• Understanding the concept of inverting dependencies for flexibility and testability
• Designing modules and components that depend on abstractions rather than concrete implementations
• Applying techniques such as dependency injection and inversion of control containers

Applying SOLID Principles in Design

• Applying SOLID principles in class and module design
• Refactoring existing code to adhere to SOLID principles
• Understanding the trade-offs and considerations when applying SOLID principles

SOLID Principles in Object-Oriented Design

• Understanding how SOLID principles relate to object-oriented design concepts
• Applying SOLID principles to improve encapsulation, cohesion, and inheritance hierarchies
• Leveraging SOLID principles to design flexible and maintainable object-oriented systems

Testing and SOLID Principles

• Designing testable code using SOLID principles
• Applying SOLID principles to improve testability and test design
• Using dependency injection and mocking frameworks for unit testing
