Bogus
:card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js. -
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. -
Testcontainers
A library to support tests with throwaway instances of Docker containers for all compatible .NET Standard versions. -
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. -
Verify
Verify is a snapshot testing tool that simplifies the assertion of complex data models and documents. -
NBomber
Distributed load-testing framework for .NET. Create distributed load test scenarios entirely using plain C# or F#. It is designed to test any system regardless of the protocol or a semantic model (Pull/Push). -
WireMock.Net
WireMock.Net is a flexible product for stubbing and mocking web HTTP responses using advanced request matching and response templating. Based on the functionality from http://WireMock.org, but extended with more functionality. -
Compare-Net-Objects
What you have been waiting for :+1: Perform a deep compare of any two .NET objects using reflection. Shows the differences between the two objects. -
MSTest
This repository holds the source code of Microsoft.Testing.Platform (MTP), a lightweight alternative to VSTest, as well as MSTest adapter and framework. -
Machine.Specifications
Machine.Specifications is a Context/Specification framework for .NET that removes language noise and simplifies tests. -
ArchUnitNET
A C# architecture test library to specify and assert architecture rules in C# for automated testing. -
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. -
Expecto
A smooth testing lib for F#. APIs made for humans! Strong testing methodologies for everyone! -
NBuilder
DISCONTINUED. Rapid generation of test objects in .NET [Moved to: https://github.com/nbuilder/nbuilder] -
Fine Code Coverage
Visualize unit test code coverage easily for free in Visual Studio Community Edition (and other editions too) -
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/) -
xBehave.net
DISCONTINUED. ✖ An xUnit.net extension for describing each step in a test with natural language. -
SpecsFor
SpecsFor is a light-weight Behavior-Driven Development framework that focuses on ease of use for *developers* by minimizing testing friction. -
Xunit.Gherkin.Quick
BDD in .NET Core - using Xunit and Gherkin (compatible with both .NET Core and .NET) -
