Simple to use library to easily cover your code with tests. No dependencies, no obscure or over-engineered pipeline, just a dead-simple framework. You can easily make use of it, it looks pleasant (especially on CI flows), and it won't slow you down anyhow.

• zpl - This is where the library has originated.
• librg - Making multi-player simpler since 2017. Single-header cross-platform world replication library in pure C99.

• Easy to use single-header framework
• No dependencies (except the standard library :)
• Works with C99 code
• Integrates well within any CI pipeline
• Supports the following checks: FAIL, UFAIL, STRFAIL, EQUALS, UEQUALS, STREQUALS, STRCEQUALS, STRCNEQUALS, STRNEQUALS, NEQUALS, LESSER, GREATER, LESSEREQ, GREATEREQ, SKIP
• Did I mention it takes a minimum time to set up?

• Either clone the repository or download unit.h.
• Include unit.h in your test app and cover your code already!

At first, we should define our entry point for the tester app:

#define UNIT_MAX_MODULES 2 #include "unit.h" /* TEST CATEGORIES */ #include "cases/some_math.h" #include "cases/cool_stuff.h" int main() { UNIT_CREATE("small"); UNIT_MODULE(math); UNIT_MODULE(cool_stuff); return UNIT_RUN(); }

As you can see, this app defines 2 test modules called: math and cool_stuff, respectively.

Let's explore them!

some_math.h

#include <math.h> MODULE(math, { IT("can do cos(0)", { EQUALS(cosf(0), 1); }); IT("can do sqrt(9)", { EQUALS(sqrtf(9), 3); }); });

cool_stuff.h

MODULE(cool_stuff, { IT("can predict the future", { // Not today ... SKIP(); }); });

As you can see, this is all it takes to cover your code, relatively simple, right? You can also skip tests you plan on running later in the future (or never :)

Have fun!
