Unit Test with Google Test

Creating your first test.

#include "gtest/gtest.h"
   
TEST(One, EqualsOne)
{
    EXPECT_EQ(1, 1);
}

As far as tests go this one is rather quick and easy to write, but it also doesn’t do much. This particular test checks to see if 1 equals 1. Let’s see if we can write a test that checks if a function called add returns the correct value.

#include "gtest/gtest.h"

int add(int a, int b) {
    return a + b;
}
   
TEST(add_function, Two_Plus_Two_Equals_Four)
{
    EXPECT_EQ(add(2, 2), 4);
}
