Macros are used for test setup only, not for test assertions. tinytest Apache 2: Yes Yes [89] Standalone, no dependencies, header-only. sTest MIT: Yes Yes Yes Yes [171] Lightweight (one header file, uses standard library). Simple to use and write tests quickly (no need to: build special constructions, create objects, use scope, catch or throw ...
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]
The term "xUnit" refers to any such adaptation where "x" is a placeholder for the language-specific prefix. The xUnit frameworks are often used for unit testing – testing an isolated unit of code – but can be used for any level of software testing including integration and system.
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.
In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution.
The JUnit team decided not to put all features within the JUnit core, and instead decided to give an extensible way for developers to address their concerns. [14] In JUnit 4, there are two extension mechanisms: the Runner API and Rule API. [15] There were some disadvantages to both the Runner API and the Rule API.

Two common uses of the assert macro are to assert that a pointer is not null and to ensure that an array index is in-bounds. [5] Below is a program using the assert macro. This program will always evaluate pointer as false, as pointer is a null pointer and does not point to a valid memory location:
