Getting Started with Bogus

Bogus is a useful .NET library used for generating fake/mock data for testing, prototyping, or populating databases.

In order to get started with Bogus, do the following activities

Installing Bogus Package

Install-Package Bogus

Configuration

Create Faker instance and Generate "fake" data

After installing the Bogus package, create a Faker instance and configure it to generate data for your desired class parameters.

Sample Usage

This is a sample use case to see how it is works:

Class to generate data for

    public class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }

Create and configure Faker instance

    var faker = new Faker<Person>()
        .RuleFor(p => p.Name, f => f.Person.FullName)
        .RuleFor(p => p.Age, f => f.Person.Age);

Generate fake data

    var fakePerson = faker.Generate();

    string Name = fakePerson.Name;
    int Age = fakePerson.Age;

You can also generate multiple fake instances of a class:

    var fakePeople = faker.Generate(5);//generates five instances with fake data

    foreach (var person in fakePeople) //Iterating through generated data and displaying on console
    {
        Console.WriteLine($"Name: {person.Name}");
        Console.WriteLine($"Age: {person.Age}");
    }
