Mini Test for C++
author: Brian J. Cardiff

1. Create simple test cases.

    void testName() {
      // test code
    }

2. Use ASSERT(<bool>) or ASSERT_EQ(<T>, <T>) where T = bool, int, string.

    void testName() {
      int m = max(3, 7);
      ASSERT_EQ(m, 7);
    }

3. Create a main entry point that list the test cases to be executed.

    int main() {
      RUN_TEST(testName);
      RUN_TEST(testName2);
      RUN_TEST(testName3);
      // etc.
    }

4. Compile & run.
