Bogus VS Fluent Assertions

Compare Bogus vs Fluent Assertions and see what are their differences.

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)

Fluent Assertions

A very extensive set of extension methods that allow you to more naturally specify the expected outcome of a TDD or BDD-style unit tests. Targets .NET Framework 4.7, as well as .NET Core 2.1, .NET Core 3.0, .NET 6, .NET Standard 2.0 and 2.1. Supports the unit test frameworks MSTest2, NUnit3, XUnit2, MSpec, and NSpec3.

  • Bogus custom Dataset
    2 projects | dev.to | 6 Jan 2024
    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.

    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() )

  • Using EF Core and Bogus
    2 projects | dev.to | 21 Jan 2023
    Going forward, the secret to knowing were to find data is to read Bogus information in the readme file which goes into depth were to find paths to generate data. This is very important as you can clash with their classes e.g. you create a Person class and guess what, Bogus has a Person class. This is were knowing how to work with using statements and using statements with aliasing.
  • Learn DateOnly & TimeOnly
    7 projects | dev.to | 15 Jan 2023
    Code samples for Json.net which as of version 13.0.2 now supports DateOnly and TimeOnly. Three code samples are used to show interactions with Bogus and Microsoft.Data.SqlClient which is most likely used to work with json data.
  • Is there a tool that could be used to generate fake unit test cases automatically for code coverage? (read description before downvoting)

Mature c# projects purposely maintain no downstream dependencies and is they do, it's to a major reputable lib. See for yourself - these are staple third party packages commonly used. Anything dependency starting with System or NETStandard is Microsoft maintained.
  • ASP.NET Core Unit Testing with FluentAssertions
    3 projects | dev.to | 21 Aug 2021
    FluentAssertions is one of the most popular (over 66 million downloads on Nuget) .NET library that contains a large collection of .NET extension methods that allow .NET developers to write unit tests using a fluent syntax which is very easy to read and write and clearly shows the intent of the unit test. The library has extension methods to test almost everything related to .NET such as Strings, Booleans, Dates, Guids, Collections, Exceptions, and even Nullable Types. You can add this library to your unit test projects via Nuget package manager and start using this library in few minutes.
  • My first NuGet package: Fluent Random Picker
    4 projects | /r/csharp | 27 Jun 2021
    I love fluency. I myself work on a package for fluent programming. I recommend you using FluentAssertions for tests though. Nonetheless, keep working! Starred your repo.
  • Honk#! Honk in convenient C# now!
    5 projects | /r/csharp | 23 Jun 2021
    For example, all tests below this line are written in Honk# + FluentAssertions (the latter is an example of a library which also provides a lot of fluent methods for xUnit to perform assertions). Soon I'll be moving more of its (AngouriMath's) code to this style, as long as it doesn't harm readability and performance.

What are some alternatives?

When comparing Bogus and Fluent Assertions you can also consider the following projects:

Shouldly - Should testing for .NET—the way assertions should be!

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.

faker-cs - C# port of the Ruby Faker gem (http://faker.rubyforge.org/)

Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]

NUnit - NUnit Framework

NFluent - Smooth your .NET TDD experience with NFluent! NFluent is an ergonomic assertion library which aims to fluent your .NET TDD experience (based on simple Check.That() assertion statements). NFluent aims your tests to be fluent to write (with a super-duper-happy 'dot' auto-completion experience), fluent to read (i.e. as close as possible to plain English expression), but also fluent to troubleshoot, in a less-error-prone way comparing to the classical .NET test frameworks. NFluent is also directly inspired by the awesome Java FEST Fluent assertion/reflection library (http://fest.easytesting.org/)

SpecFlow - #1 .NET BDD Framework. SpecFlow automates your testing & works with your existing code. Find Bugs before they happen. Behavior Driven Development helps developers, testers, and business representatives to get a better understanding of their collaboration

NBuilder - Rapid generation of test objects in .NET

xUnit - xUnit.net is a free, open source, community-focused unit testing tool for .NET.

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.
