 # Details
 This class collection ( or class library ) encapsules the certain data structure of Pico SDK behind the classes. And it also allows programmers to use the dependency-injection in their projects. So, programmers can test their code with [Google Test](https://github.com/google/googletest) before testing on the target hardware.
