wtf is cwing?

CWing is a minimal unit testing library for the C programming language. It gives C programmers a lightweight tool to write and run small tests that check whether individual pieces of their code work as expected, without pulling in a heavy framework or complex dependencies. In practice, unit tests are short snippets of code that call a function with known inputs and verify the output matches what you expect. For example, if you wrote a function that calculates a discount, a unit test might feed it a $100 purchase and a 20% discount rate, then confirm it returns $80. When you run your test suite, the library reports which checks passed and which failed, so you can catch bugs early before they cause headaches downstream. This tool would appeal to C developers working on smaller projects, embedded systems, or any codebase where keeping things lean matters. Someone writing firmware for a microcontroller, for instance, might want to test their logic without adding a sprawling dependency. A student learning C could also use it to practice writing tests alongside their assignments and build good habits. The main draw is simplicity: it focuses on doing one thing without getting in your way. The README doesn't go into detail about specific features, API design, or how the library is structured internally. What's clear from the description is the emphasis on being "tiny," which signals that the project trades breadth for minimalism. If you need a no-frills way to add basic test coverage to a C project, this is the kind of tool that aims to stay out of your way rather than imposing opinions about how you should structure your code.
