CuTest: C Unit Testing Framework

Overview

CuTest is a unit testing library for the C language. It can be used to do Extreme Programming and Test-First Development in the C language. It's a fun and cute library that will make your programming fun and productive.

Benefits

• Lower Defects. The tests ensure that your code keeps working as you make small changes in it.
• Faster Debugging. The tests tell you which subroutine is broken. You avoid spending hours trying to figure out what's broken.
• Development Speed. You trust your old code and can keep adding to it without worrying about bad interactions. If there is a bad interaction the tests will catch it.
• Permanent Bug Fixes. If every time a bug is reported you write a quick test, you will guarantee that the bug never reappears again.
• Fun. As your bug count drops you will begin to enjoy programming like you've never done before. Running the tests every few minutes and seeing them pass feels good.

Features

• Small. Consists of a single .c and .h file.
• Easy to Deploy. Just drop the two files into your source tree.
• Highly Portable. Works with all major compilers on Windows (Microsoft, Borland), Linux, Unix, PalmOS.
• Open Source. You can extend it to add more functionality. The source can be invaluable if you are trying to trace a test failure.
• Cuteness. Of all the testing frameworks CuTest has the cutest name :-)
