A test fixture (also known as a test context) provides the environment for each test case of a suite. Generally, a fixture is configured to setup a known, good, runtime environment before tests run, and to cleanup the environment after. The fixture is configured with one or more functions that setup and cleanup state.
Class-level setup is implemented using the @BeforeAll annotation. The other type is setup before running each test case, which uses the @BeforeEach annotation. [5] Test execution - This phase is responsible for running the test and verifying the result. The test result will indicate if the test result is a success or a failure.
Powerful dataset concept for generating test cases. Different levels of fixtures (global, once per test suite, once per each test case in a suite). Powerful floating point comparison.

Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.
Test fixtures can be set up three different ways: in-line, delegate, and implicit. In-line setup creates the test fixture in the same method as the rest of the test. While in-line setup is the simplest test fixture to create, it leads to duplication when multiple tests require the same initial data.
xUnit.net is a free and open-source unit testing tool for the .NET Framework, written by the original author of NUnit. The software can also be used with .NET Core and [2] Mono. It is licensed under Apache License 2.0, and the source code is available on GitHub. [3] xUnit.net works with Xamarin, ReSharper, CodeRush, and TestDriven.NET. [4]
Before NUnit 2.4, a separate method of the Assert class was used for each different assertion. It continues to be supported in NUnit, since many people prefer it. [citation needed] Each assert method may be called without a message, with a simple text message or with a message and arguments.
