Also given that the feature really just arrived in clang 10 in the last month and gcc 10 isn't yet released almost no one has reacted to operator<=> yet.  All that said, most stuff like boost.test that uses operators shouldn't need to be modified.  A deeper possibility here is boost.test is fine and that Leo might need to implement operator== with the operator<=>.  Have a look thru this blog post https://brevzin.github.io/c++/2019/07/28/comparisons-cpp20/

One of the changes of C++20, coming with operator<=>, is rewritten
candidates for comparison operator overload resolution, which has been
causing massive breakage among any significant C++ codebase. Many
people have already been submitting patches for these for the last six
months in various software packages, Boost included.
