xUnit

xUnit is a framework used by developers to automatically test small parts of their software, called units. These tests ensure that individual functions or modules work correctly and help catch errors early. By writing test cases following the xUnit structure, developers can quickly verify that their code behaves as expected after changes. It provides a standardized way to organize, run, and assess tests, improving software quality and maintainability. Popular xUnit frameworks include JUnit for Java and NUnit for .NET, all sharing common principles for effective testing.
