This is a simple C / C++ unit testing framework with no non-standard deps. You can use it in your EECS projects, assuming of course that doing so does not violate the code use, or honor code restrictions, by which you MUST abide.

First, clone the framework into your project folder:

git clone https://github.com/michiganhackers/unit-test-framework.git

If you want to have a folder specifically for tests, run mkdir tests on the root level of your project and add a test file:

#include "../unit-test-framework/unit_test_framework.h"

int main(int argc, char const *argv[])
{
  // Describe the suite of tests to be run.
    start_suite("Start test suite:");
    
  // Run some tests.
    if( assertEqual(1, 1) )
	    test_passed("1 is equal to 1!");
    else
	    test_failed("1 is not equal to one.");
    
  // End the suite
    end_suite();
    return 0;
}

Compile at the project's root folder:

g++ tests/test.cpp -o test unit-test-framework/unit_test_framework.c

Run your test suite:

./test

That's it!

Maybe you want this to be a little more like JUnit in Java, or you just like organizing a test into its own function, and sharing setup and takedown functions between tests.

1. Write your before/setup function. By default, a setup function that does nothing is used.

   void setup(void) {
     // Do some setup here, probably set some global variables
   }
   

2. Write an after/takedown function. By default, a takedown function that does nothing is used.

   void takedown(void) {
     // Get everything back to a clean slate
   }
   

3. Register the callbacks

   setBeforeFunc(before);
   setAfterFunc(after);
   

4. Write some test function

   void test1() {
       // Set some variables using global variables set during setup()
       if( assertEqual(something, something_from_setup) )
           test_passed("Yay!");
       else
           test_failed("Boo!");
   }
   

5. Run the test

   runTest(test1, "Test 1");
   

Now execution of test1() is wrapped inbetween calls to setup() and takedown().
