tests/micropython/viper: Boundary value tests depend on arbitrary ints.

projectgus · projectgus · commit d2517f123a66 · 2025-07-22T11:22:09.000+10:00
Skip the tests if MicroPython can't represent &gt;64-bit integers
(these tests repeatedly left shift values by 8 bits).

It would be possible to have these tests work in this case I think,
as the results are always masked to shorter values. But quite fiddly.

This work was funded through GitHub Sponsors.
