What are the 5 SOLID principles?

What are the 5 SOLID principles?

SOLID is an acronym that stands for five key design principles: single responsibility principle, open-closed principle, Liskov substitution principle, interface segregation principle, and dependency inversion principle. All five are commonly used by software engineers and provide some important benefits for developers.

What is refactoring code?

Code refactoring is defined as the process of restructuring computer code without changing or adding to its external behavior and functionality. There are many ways to go about refactoring, but it most often comprises applying a series of standardized, basic actions, sometimes known as micro-refactorings.

What is SOLID principle in programming?

What is SOLID principle with example?

This principle suggests that “parent classes should be easily substituted with their child classes without blowing up the application”. Let’s take following example to understand this. Let’s consider an Animal parent class. Now let’s consider the Cat and Dog classes which extends Animal.

What is code refactoring in Agile?

Refactoring is the activity of improving the internal structure or operation of a code or component without changing its external behavior. The goal of software development is the continuous delivery of business value to users and stakeholders.

What is refactor in TDD?

TDD is powerful and practical. It’s the practice of always writing test code before the code to be tested. Refactoring is a disciplined design skill to improve the structure of code without changing its external behavior. And refactoring is part of the TDD cycle.

Can you explain SOLID principle?

SOLID Principles is a coding standard that all developers should have a clear concept for developing software properly to avoid a bad design. It was promoted by Robert C Martin and is used across the object-oriented design spectrum. When applied properly it makes your code more extendable, logical, and easier to read.

What is refactoring and design patterns?

Refactoring is a systematic process of improving code without creating new functionality. Refactoring transforms a mess into clean code and simple design. Design Patterns are typical solutions to commonly occurring problems in software design. They are blueprints that can be taken and customized to solve a particular design problem in your code.
