CUnit

CUnit is a unit testing framework for the C programming language. It provides a set of tools and macros to help developers write, organize, and run tests for their C code. The primary goal of CUnit is to facilitate the process of unit testing, which involves verifying small, isolated parts of a program to ensure they function correctly.

The framework allows developers to define test suites, which are collections of individual tests. Each test is designed to check a specific function or piece of code. CUnit provides functions for setting up test environments before a test runs and for cleaning them up afterward. It also includes assertions, which are statements that check for specific conditions within a test. If an assertion fails, the test is marked as failed.

CUnit supports various assertion types, such as checking for equality, inequality, greater than, less than, and null pointers. It can report test results in different formats, making it easy to integrate with other build tools and continuous integration systems. The framework is known for its simplicity and ease of use, making it a popular choice for developers working on C projects. It helps in identifying bugs early in the development cycle and improving the overall quality and maintainability of the code.
