Why do we use unit test in C#?
Unit testing breaks the program down into the smallest bit of code, usually function-level, and ensures that the function returns the value one expects. By using a unit testing framework, the unit tests become a separate entity which can then run automated tests on the program as it is being built.

What is NUnit testing?
NUnit is an open-source unit testing framework for the .NET Framework and Mono. It serves the same purpose as JUnit does in the Java world, and is one of many programs in the xUnit family.
What is a constraint based model?
This approach uses a single method of the Assert class for all assertions, passing a Constraint object that specifies the test to be performed. This constraint-based model is now used internally by NUnit for all assertions. The methods of the classic approach have been re-implemented on top of this new model.
What happens if a method fails in nunit?
NUnit provides a rich set of assertions as static methods of the Assert class. If an assertion fails, the method call does not return and an error is reported. If a test contains multiple assertions, any that follow the one that failed will not be executed. For this reason, it's usually best to try for one assertion per test.

Should I use NUnit or xUnit?

What is Xunit different from?
xUnit framework is different from NUnit and MSTest frameworks on multiple fronts. Let’s look at the core differences:
What is xunit.net?

What is mstest in Visual Studio?
MsTest is a native unit testing library that comes with Visual Studio from Microsoft. NUnit is an extra Nuget package that needs to be installed on top and interact with the APIs of Visual Studio. Nunit likely doesn’t have direct integration into the native APIs like MsTest does.

Why is parallelization important in unit testing?
A unit testing library that has poor parallelization is automatically at a massive disadvantage because it will slow down your continuous integration pipeline.
Is Mstest faster than Visual Studio?
I don’t have hard data on this, but from my experience and intuition, it only makes sense that MsTest is faster with its tight integration with Visual Studio.

Parallelization at the Class aka Fixture level with NUnit is just fine. The problem arises when you want to parallelize at the method aka test method level.
Is MsTest affected by software changes?
MsTest is less likely to be impacted by future changes to software.
Can you reuse nunit?
The key here is that you cannot reuse the SetUp and Teardown from NUnit and have to write your own.
How does xunit.net differ from nunit?
So, in NUnit, we've got a test class and a set of test methods in it. NUnit creates a new instance of the test class and then runs all of the test methods from the same instance. Whereas xUnit.net creates a new instance of the test class for very each of the test methods. Therefore, one cannot use fields or properties to share data among test methods which is a bad practice, as our test methods would be dependent to each other which is not acceptable in TDD. So if you use xunit.net, you could be sure that your test methods are completely isolated.
What is xunit.net?
xUnit.net is a unit testing tool for the .NET Framework. Written by the original inventor of NUnit
What is the benefit of xunit?
One benefit of xUnit is that it finds tests in different classes and runs them in parallel. This can save a lot of time if you have many test cases.

Making statements based on opinion; back them up with references or personal experience.
Does Xunit work with console?
XUnit doesn't work with Console.WriteLine (), while NUnit does.
Is xunit.net parallel or nunit?
Both frameworks are awesome, and they both support parallel test running (in a different way though). NUnit has been around since 2002, it's widely used, well documented and has a large community, whereas xUnit.net is more modern, more TDD adherent, more extensible, and also trending in .NET Core development. It's also well documented.
Can you break isolation in xunit?
If you're willing to share some data among your test methods though, xUnit will let you do so. Therefore, by default all test methods are completely isolated, but you can break this isolation in specific cases intentionally. I fancy this attitude, that's why I like it better.
Overview
NUnit is an open-source unit testing framework for the .NET Framework and Mono. It serves the same purpose as JUnit does in the Java world, and is one of many programs in the xUnit family.
Features
• Tests can be run from a console runner, within Visual Studio through a Test Adapter, or through 3rd party runners.
• Tests can be run in parallel.
• Strong support for data driven tests.
• Supports multiple platforms including .NET Core, Xamarin Mobile, Compact Framework and Silverlight.
Assertions
NUnit provides a rich set of assertions as static methods of the Assert class. If an assertion fails, the method call does not return and an error is reported. If a test contains multiple assertions, any that follow the one that failed will not be executed. For this reason, it's usually best to try for one assertion per test.
Nunit 3.x is supporting multiple assertions.
Example
Example of an NUnit test fixture:
The NUnit framework discovers the method ExampleTestOfNUnit.TestMultiplication() automatically by reflection.
Extensions
FireBenchmarks is an addin able to record execution time of unit tests and generate XML, CSV, XHTML performances reports with charts and history tracking. Its main purpose is to enable a developer or a team that work with an agile methodology to integrate performance metrics and analysis into the unit testing environment, to easily control and monitor the evolution of a software system in terms of algorithmic complexity and system resources load.

Prerequisites
- .NET Core 2.1 SDKor later versions.
- A text editor or code editor of your choice.
Creating The Source Project
- Open a shell window. Create a directory called unit-testing-using-nunitto hold the solution. Inside this new directory, run the following command to create a new solution file for the class library and the test project: Next, create a PrimeServicedirectory. The following outline shows the directory and file structure so far: Make PrimeServicethe cu...
Creating The Test Project
- Next, create the PrimeService.Testsdirectory. The following outline shows the directory structure: Make the PrimeService.Testsdirectory the current directory and create a new project using the following command: The dotnet new command creates a test project that uses NUnit as the test library. The generated template configures the test runner in the PrimeService.Tests.csprojfile: T…
Creating The First Test
- You write one failing test, make it pass, and then repeat the process. In the PrimeService.Tests directory, rename the UnitTest1.cs file to PrimeService_IsPrimeShould.csand replace its entire contents with the following code: The [TestFixture] attribute denotes a class that contains unit tests. The [Test]attribute indicates a method is a test method. Save this file and execute the dot…
Adding More Features
- Now that you've made one test pass, it's time to write more. There are a few other simple cases for prime numbers: 0, -1. You could add new tests with the [Test] attribute, but that quickly becomes tedious. There are other NUnit attributes that enable you to write a suite of similar tests. A [TestCase] attribute is used to create a suite of tests that execute the same code but have diff…
