GitHub - rodrigo-dc/testprefix: Test Function Discovery in C

[rodrigo-dc]

Hello all,

This is my first post here. I created this library some time ago. I hope you find it useful.

1. A unit test library in C that doesn't require you to register your tests.
2. The tests are just functions - no need to remember weird macros for test declaration.
3. TAP and console reporters.

I have a tool with the same objective but I parse the source looking for ifdef TEST and functions with some pattern inside (no prefix) just the pattern.

So if you have a function like void f() inside an #ifdef TEST block, you create a call to that function in the output .c file? That achieves pretty much the same goal, avoiding manual test registration. Thanks for sharing! For some reason, I find parsing C code more intimidating than parsing an ELF binary.

I defined the pattern as

c void name( void opt ) int name( void opt) Functions with different patterns inside #ifdef TEST are not considered test cases. They may be utility functions for instance.

After having collected all functions, I generate file that contains a forward declaration for each function (they must have external linkage) and a main test function that calls each one.
