Bogus
:card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js. (by bchavez)
AutoFixture
AutoFixture is an open source library for .NET designed to minimize the 'Arrange' phase of your unit tests in order to maximize maintainability. Its primary goal is to allow developers to focus on what is being tested rather than how to setup the test scenario, by making it easier to create object graphs containing test data. (by AutoFixture)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Effective Strategies for Writing Unit Tests with External Dependencies like Databases and APIs
Sometimes, especially when testing data-driven applications, it is important to simulate a wide variety of inputs and conditions. One of the best ways to achieve this is by using fake data generators. Tools like Faker (Python) or Bogus (C#) allow you to generate large volumes of realistic but random data. This is particularly useful when you need to test how your code handles various types of data (such as user information, addresses, or product details) without relying on real data.

Bogus DateOnly/TimeOnly
Bogus NuGet package data generator provides methods to work with DateOnly and TimeOnly that are not documented, learn these methods using an ASP.NET Core project and class project.

ASP.NET Core Integration Testing Best Practises
For assertions inside tests, I recommend using FluentAssertions Library. And if you want to generate some fake data for your tests, I recommend using Bogus.

Bogus custom Dataset
Bogus NuGet package is fake data generator which can be helpful for populating tables in a database and testing purposes. If a database is not used and Bogus populates list of data each time an application runs, the data is random, never the same. Also, the random data generated by Bogus may not meet a developer’s requirements.

Should I give a copy of the database to the developer
That reminds me of Bogus which also generates dummy data that I've been using for sometime now.

Best practices for organising Mock Data & Repositories in Testing
To do all this you need test though...and that's where ]Bogus](https://github.com/bchavez/Bogus) and Auto Bogus come in handy. They both generate semi random test data that you can use to populate whatever method you've decided to use. You can setup rules so for specific fields, they have built in generators for common things like names and addresses. Auto Bogus can be used to populate large/complicated objects with data automatically (it can be slow if you don't use .WithRecursiveDepth() or.WithTreeDepth() )

You probably don't need a dependency injection framework
His AutoFixture C# NuGet takes away so much pain from unit test maintenance. It does have a learning curve.

API: Go, .NET, Rust
Yes, it does feel like some of the "standard stuff" in other more nuanced languages are missing (especially miss AutoFixture ngl). Some of those are a conscious decison by the golang team for example.

Integration Testing Postgres Store
Our first test is very easy, I like to name my tests as MethodName_GivenCondition_ShouldExpectedResult to follow the pattern, I have added GetById_GivenRecordDoesNotExist_ShouldReturnNull and I am going to leavarage excellent AutoFixture to get a new Guid as parameter. For this test we don't need arrange part, we would skip to the act and then assert. For Assertion I am going to use FluentAssertions. For this test we need to assert the returned result is null.

Setting up a simple testing project with C#
The next test to talk about, is that if this was a bank, we would have multiple customers, who can hold multiple accounts that we need to calculate the interest for. You could manually construct these objects if you want, but I'm going to use a package called AutoFixture to make life easier.

AutoFixture Tips and Tricks
AutoFixture is an amazing library that simplifies the process of creating test data in .NET. If for some reason you don't use this fantastic tool, it's time to consider it. Today, I'm going to share some tips for using AutoFixture that will be beneficial for developers of all skill levels. Let's get started!
- Integration tests without API dependencies with ASP.NET Core and WireMock.Net

Reduce your tests cognitive complexity with AutoFixture
Ensuring that your test is still readable and not bloated by the setup of those variables may be quite a challenge but hopefully no more with AutoFixture, let's see how!

One neat library for creating and generating test data is AutoFixture. The creators describe it as follows:

14 .NET packages I always recommend
First time I heard of Bogus, looks interesting, been using AutoFixture for those will definitely take a look at it.
What are some alternatives?
When comparing Bogus and AutoFixture you can also consider the following projects:
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
NSubstitute - A friendly substitute for .NET mocking libraries.
FakeItEasy - The easy mocking library for .NET
GenFu - GenFu is a library you can use to generate realistic test data. It is composed of several property fillers that can populate commonly named properties through reflection using an internal database of values or randomly created data. You can override any of the fillers, give GenFu hints on how to fill them.
