test.h

A minimalistic test harness for c code.

Usage

#include "test.h"

BEGIN_TEST();

#define true 1
#define false 0

void test_bools()
{
  ASSERT(1 == true);
  ASSERT(0 == false);
}

void test_ints()
{
  ASSERT(1 == 1);
  ASSERT(0 == 1);
}

int main(void)
{
  TEST(bools);
  TEST(ints);
  TEST_REPORT();
  return TEST_RESULT();
}

Output:

# Testing bools
[OK] 1 == true
[OK] 0 == false

# Testing ints
[OK] 1 == 1
[FAIL] 0 == 1 (at line 17)

# Result
[OK]    3
[FAIL]  1

Api

Exposes the following set of macros:

BEGIN_TEST();

Call this macro at file scope. This sets up test counters.

TEST(function);

Print out a text and call function test_function().

ASSERT(expr);

Evaluate an expression. Does the following:

• Evaluate expr
• If expr is true print out message and increment counter for successful tests
• If expr is false print out message (using __LINE__) and increment counter for failed tests

ABORT(expr);

Like ASSERT(expr) but exits process directly. Useful if you don't want to continue testing for some reason to not end up in infinite loops etc.

TEST_REPORT();

Print out test report.

TEST_RESULT();

Return this in your main (or use with exit()) for proper exit code.
