I am facing a lot of issues with Unity Test Framework.

Simple test.cpp file #include <unity.h>

// Function to be tested
int add(int a, int b) {
return a + b;
}

// Test case for addition
void test_add_function() {
TEST_ASSERT_EQUAL(5, add(2, 3));
TEST_ASSERT_EQUAL(0, add(-1, 1));
TEST_ASSERT_EQUAL(-3, add(-1, -2));
}

void setup() {
// Initialize Unity Test Framework
UNITY_BEGIN();

// Run test cases
RUN_TEST(test_add_function);

// End Unity Test Framework
UNITY_END();

}

void loop() {
// Not used in testing; left empty
}
