  REST (Representational State Transfer) is an architectural style for designing networked applications. It relies on a stateless, client-server, cacheable communications protocol -- the HTTP protocol is almost always used. REST APIs are widely used in web services and are a key part of modern web development. ###   What are REST API Standards? REST API standards are a set of conventions and best practices for designing and implementing RESTful web services. These standards ensure consistency, scalability, and maintainability of APIs. Key principles include: 1. **Statelessness**: Each request from a client to a server must contain all the information needed to understand and process the request. 2. **Client-Server Architecture**: Separation of concerns between the client and server. 3. **Uniform Interface**: Consistent and standardized ways of interacting with the API (e.g., using HTTP methods like GET, POST, PUT, DELETE). 4. **Resource-Based**: Resources (e.g., users, product...

NUnit Testing in ASP.NET CORE MC

  Let’s implement  NUnit unit testing  for an  Employee Management System  in ASP.NET Core MVC, incorporating a  service layer  and  repository layer , and setting it up entirely within  Visual Studio 2022  (without CLI commands).  I’ll provide a step-by-step explanation with source code, comments, proper naming conventions, coding standards, and test results for the use case involving  Employee ,  Department ,  Project , and  Task .  We’ll focus on what each part does, why it’s used, and how to configure it in Visual Studio 2022. Step 1: Understand the Setup What Build an MVC project with a service layer (business logic), repository layer (data access), and a test project using NUnit in Visual Studio 2022. Why Service Layer : Encapsulates business logic (e.g., assigning tasks), testable independently of data access. Repository Layer : Abstracts data operations (e.g., in-memory or database), making tests moc...
