# Stubser is a stub creator for CUnit
In an existing project, which does not use unit tests yet or which is still under heavy development, it is always a tedious task to create stubs for existing code. This GNU C based application takes one or multiple (also recursively) C files to create functional stubs ready to use with CUnit. Following files are created from on input C file:
| Input | Output | Description |
| -------- | -------- | ------- |
| myfile.c | stub_myfile_user.c | Define additional elements which need to be tested, or helper functions. |
||stub_myfile_user.h | Define test subject header needed for compilation of this stub including e.g. typedefs, structures, etc.. |
||stub_myfile.c| Actual stub containing all global variables and functions. |
||stub_myfile.h| Header exposing all functions needed by CUnit test suite. |
Stubser can be called repeatedly to the same output directory. It won't overwrite existing \*_user.c|h files. This makes it possible to use it alreday during development in early stages.
## Regular Expression based C file parser
This is a personal "experience collection" project to get more familiar with regular expressions in general, but also the use of it in GNU C. The focus is therefore not on performance.
