CppUnitLite basic test approach confirmation

[mrpear2020]

Hello, imagine the requirement is:
Use CppUnitLite and use stringstream instead of atoi and sprintf.
Write a test to read and write a double.

I did the below. Calling this from main, it prints:
*** STARTING TEST ** 1 tests, 0 failures, 0 errors

Can you please confirm this has accomplished the requirement? First time I am using CppUnitLite

#include "TestHarness.h"
#include <iostream>

TEST(toDouble, stringstream)
{

cout << "** STARTING TEST **";
std::stringstream dValue("32.1");

double value;
value = 32.1;

dValue >> value;
if (!dValue)
{
CHECK_FAIL("Failed")
}
CHECK_EQUAL(32.1, value);
}
