ASSERT_EQ does not work with refrence about aunit HOT 3 OPEN

May be a solution is to use remove_reference:

#define ASSERT_EQ(expected, actual)                     \
    assertEqual(                                        \
        static_cast< std::remove_reference<             \
                decltype(actual) >::type >(expected),   \
        actual)

But remove_reference is not support in current Arduino version (1.8.19) so you need also ArxTypeTraits 0.2.3 by Hideaki Tai.

Maybe the solution is to remove the static_cast<decltype(a)>? See if the following helps:

It fixes your specific problem.

I don't have any code that uses <gtest.h>, and I'm not entirely sure I understand all the edge cases of the Google Test framework, so not really sure if this is the best solution.

Thanks for your suggestion to remove the static_cast. Yes
that fixes my problem. I thought the static_cast has
the intention to select the correct function from
the set of overloaded assertEqual(). I hoped be the original
author of gtest.h did know.

I'm porting some Tests from x86 to arduino. So I'm doing further
testing with my variant using remove_reference.
So far it seems to work fine. Only disadvantage is that ArxTypeTraits
is required.
