Your reply led me find TEST_ASSERT_EQUAL_PTR(), which is what is most appropriate in this case.

Thanks.

Hi!

[quote user=""]This is because TEST_ASSERT_EQUAL() casts both values to UNITY_INT.
And, I've ascertained that UNITY_INT in my environment resolves to 64 bits, while the pointers are 32 bits.[/quote]

Sorry for the delay. So if there is a mismatch here, maybe you could try to use TEST_ASSERT_EQUAL_INT32() or TEST_ASSERT_EQUAL_UINT32(), instead of TEST_ASSERT_EQUAL() ?

Hello,

Still waiting on a response on this.

It has been almost 3 weeks.

Thanks!

Hi, I'm wondering if there have been any further thoughts on this.

A clarification: The definition/assignment of my_pointer is inside one of my test functions. In other words, it's kind of like:

void test_my_feature(void) {

    struct device const * const my_pointer = function_that_I_want_to_test(some_value);

    TEST_ASSERT_EQUAL(DEVICE_DT_GET(DT_NODELABEL(some_node)), my_pointer);

}

So, the static keyword is not of use here.

But I did try changing the line to your suggestion, for the fun of it. It still gave the "cast from pointer to integer of different size" error (not surprisingly, I think - it doesn't address the width difference), and furthermore, gave "initializer element is not constant" due to the static.

Also for the fun of it, I tried changing to:

struct device const * my_pointer = function_that_I_want_to_test(some_value);

(i.e., dropped the second "const" - i.e., just a pointer to a const, not a const pointer to a const). Still got "cast from pointer to integer of different size".

Hi!

[quote user=""]struct device const * const my_pointer = some_value;[/quote]

Could you try this instead?

static const struct device *my_pointer
