Assertion

Add deep object comparison to your NUnit assertions. Simply use Is.DeepEqualTo in place of Is.EqualTo.

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. Works with .NET Standard 2.0 and higher, .NET Framework 4.7 and higher and .NET 6 and higher. Supports the unit test frameworks MSTest2, NUnit3, NUnit4, XUnit2, XUnit3, MSpec and TUnit. IMPORTANT: This version is free for open-source projects and non-commercial use, but commercial use requires [a paid license](https://xceed.com/products/unit-testing/fluent-assertions/). Check out the [license page](LICENSE) for more information.

Helper library that helps assert assumptions in the code.

Deprecated, use Flurl.Http https://www.nuget.org/packages/Flurl.Http/

Value Type Assertions

Several useful extensions to the Should Assertion Library for testing different type and enumerables of those type for equality. Like the Should extensions themselves, these extensions provide assertions only, and therefore are also test runner agnostic. I've been using these extensions in projects for several years and thought they would be useful for others.

Package Description

A no frills library for validating arguments.

Contains Moq argument matchers using FluentAssertions

Method Chaining base UnitTesting Extensions for MSTest V2

MVC Route Unit Tester provides convenient, easy to use methods that let you unit test the route table in your ASP.NET MVC application, including Area routes. Unlike many libraries, this lets you test routes both ways -- both incoming and outgoing. You can specify an incoming request and make one of several assertions about the outcome; such that the request matches a given route, matches no routes, or that it is ignored by the routing system. You can also specify route data and assert that a given URL will be generated by your application. Works with any unit testing library you choose, such as MSTest, NUnit, xUnit, mbUnit, and others. See the Project site for usage details.

Analyzers to help writing fluentassertions the right way.

Package Description

A simple diff comparison asserter that makes it easy to assert if two texts (strings) are equal, and display the differences in a diff tool if they are not. Simply put it is a much simpler (and dumber) version of ApprovalTests that should get the job done for simple scenarios. You can easily create a file that contains the expected result (your specification or example) and then compare the contents of the file with the actual value that is produced during the test. A new addition is the ability to compare objects wihout using files. It is an extension of FluentAssertions that allows comparison and exclusion of complex objects.

A set of assertions to be used together with FluentAssertions library.

A Sitecore-like assertions library. Introduced in SIM 1.x, forked to be polished and amazing.

Fail early. Fail often. Guard assertions + code contracts. (Warning: Interface is likely to change wildly between versions. Use with caution.)

SmartTests enables you to write Smarter unit tests, wether you use NUnit, Xunit or MSTests. It is best to install SmartTests.Analyzer and SmartTests.Extension so that missing tests will be displayed. They are Smart in the sense that: 1. The Act line of your test is instantly identifiable. 2. You express your Act logical intent and the optional Analyzer will display all missing tests. 3. You can use smarter assertions than the ones provided by usual Testing Frameworks as Smart Tests knows what is your Act and when it is run. a. You ensure that a PropertyChanged event is raised with only one line of code. b. You ensure that any event is raised with only one line of code. c. You ensure that an object didn't changed at all with only one line of code. d. You ensure that your property set is effective by checking its value after is not equal to its value before with only one line of code. e. You show each effect of your Act code relatively to its previous value with only one line of code.
