Unittest, Servicector, and Automapper in C# development

When it comes to C# programming, three essential terms that are widely used are Unittest, Servicector, and Automapper. Each of these terms plays a vital role in different phases of development. Let's discuss each term in detail.

Unittest

As the name suggests, Unittest is a type of testing where individual units of code are tested. It is imperative to ensure that each small piece of code is working correctly before integration. Unittest is a part of TDD (Test Driven Development) and is primarily used to catch defects in the code. It helps developers ensure that each small piece of code is working as expected. In C#, NUnit, xUnit, and MSTest are the most popular unittest frameworks.

Servicector

Servicector is an essential part of the application architecture that focuses on separating the business logic into a separate project. It helps in creating highly maintainable and scalable web applications. In C#, Servicector is implemented using the Dependency Injection principle.

The primary goal of Servicector is to divide the whole application into small, independently testable components. It also helps in separating concerns and making code more modular. Servicector plays a crucial role in building applications that are highly modular, maintainable, and scalable.

Automapper

In C# programming, Automapper is a powerful yet straightforward tool that helps in mapping objects between different classes. It is a NuGet package that can be installed in your project. Automapper helps developers reduce the effort and time required for mapping objects between different classes.

With Automapper, you can quickly write code that maps from a source object to a destination object. Automapper automatically maps properties with the same name. Developers can also manually configure how the mapping occurs.

Example code snippet for Automapper:

using AutoMapper;
public class Customer {
    public string Name { get; set; }
    public string Address { get; set; }
    public string Phone { get; set; }
}
public class CustomerDTO {
    public string CustomerName { get; set; }
    public string CustomerAddress { get; set; }
    public string PhoneNumber { get; set; }
}
public class CustomerProfile : Profile {
    public CustomerProfile() {
        CreateMap<Customer, CustomerDTO>()
            .ForMember(dest => dest.CustomerName, opt => opt.MapFrom(src => src.Name))
            .ForMember(dest => dest.CustomerAddress, opt => opt.MapFrom(src => src.Address))
            .ForMember(dest => dest.PhoneNumber, opt => opt.MapFrom(src => src.Phone))
        ;
    }
}

In summary, Unittest, Servicector, and Automapper are essential parts of C# development. Unittest ensures that each small piece of code is working as expected. Servicector helps in creating highly maintainable and scalable web applications. Automapper simplifies the mapping process between different classes.
